    Among soil erosion processes, the initial stage of splash soil erosion caused by throughfall kinetic energy (TKE) plays a crucial role in soil conservation within forest ecosystems. Throughfall (TF) through the upper canopy structure considerably influences TKE in coniferous plantations. Recent studies have revealed that the under-canopy structure laden with dead branches in unmanaged coniferous plantations reduces the TF; however, its specific impacts on TKE and appropriate sampling strategies remain unexplored. This study used 40 splash cups (4 for free kinetic energy and 36 for TKE) for one event (total: 600 splash cups for 15 events) in an unmanaged 36-year-old Japanese cypress plantation laden with dead branches. Additionally, unstratified and stratified Monte Carlo simulations were used to determine optimal sample sizes for stand-scale TKE estimation. Results demonstrated a strong correlation between TKE (J m−2) and TF (mm) (R2 = 0.98) across all events. The stand-scale unit TKE of 12.5 J m−2 mm−1 was much lower than those in seven previous studies with fewer or no dead branches (range: 16.4 to 28.2, median: 18.8 J m−2 mm−1). The previously developed empirical stand-scale unit TKE model considering under-canopy structure solely exhibited a 1.7-fold overestimation. Among the stand structures, a positive relationship of TKE with the distance between a sampling point and its nearest trunk (Dmin) was observed, which was positively correlated with the lowest dead branch height. This indicated that under-canopy dead branches weakened the TKE, likely by reducing TF and raindrop fall velocity. Stratified Monte-Carlo simulation considering the Dmin related spatial patterns of TKE provided a more efficient approach for capturing variability. To achieve high precision with potential errors of ≤5–10 %, a total sample size of 6–15 was appropriate. Our findings implied that the presence of under-canopy dead branches mitigates the soil erosion risk in unmanaged Japanese cypress plantations.

    Restoration of natural secondary forests and afforestation of introduced tree species are major effective measures for revegetation. The semiarid Loess Plateau region, characterised by fragile ecosystems and severe soil erosion, is a key area for ecological restoration and protection in China. To illustrate water use characteristics and adaptation to drought in the main forests in this area, we monitored the xylem sap flow of two typical adjacent forest communities with similar climatic characters, a secondary natural forest dominated by oak (Quercus liaotungensis) and a pure plantation of black locust (Robinia pseudoacacia), during 2011–2019 using Granier-type thermal dissipation probes. Solar radiation (RS), air temperature, relative humidity (RH), precipitation and soil water content (SWC) were measured simultaneously. Throughout the whole study period, the mean diameter at breast height (DBH) and total sapwood area increased by 4.5 cm and 1.10 m2 ha−1, respectively in the oak forest and by 1.0 cm and 0.22 m2 ha−1, respectively in the black locust plantation. The monthly stand transpiration was jointly determined by phenological and meteorological factors. At the annual timescale, transpiration of the oak stand was significantly correlated with potential reference evapotranspiration (ET0) and rainfall in the previous year, whereas a significant positive relationship was detected between stand transpiration and SWC in the black locust stand. The analyses of differences between dry and wet years showed that the oak forest exhibited significantly different parameters in the regression analysis of stand transpiration to vapour pressure deficit (VPD), whereas only one parameter was clearly distinct in the black locust plantation, suggesting that its transpiration status did not fully recover even in wet years. The management of black locust plantations with weakened growth conditions should be adjusted under prolonged drought conditions. In contrast, oak forest can maintain the water balance and stable growth by efficiently controlling stomatal behaviour.

    Evapotranspiration is an essential process of ecosystem water consumption and is controlled by meteorological factors and soil water conditions. In this study, evapotranspiration based on soil water budget was investigated with respect to major influencing factors during the growing seasons of 2012–2015 for two adjacent forest communities in the semiarid Loess Plateau region: a natural secondary forest dominated by oak (Quercus liaotungensis) and a plantation of exotic black locust (Robinia pseudoacacia). Based on the combination of precipitation, soil water storage, and evapotranspiration dynamics, four distinct periods were differentiated to explore the evapotranspiration response to the main meteorological factors. The correlation matrixes showed that, in most investigated days, evapotranspiration was limited by soil water storage, while an increase in soil water storage shifted dominance from water-related to energy-related factors. The stepwise regression of ≥5-day dry events in each period had a better fitness when paired with the relationship between the summations of evapotranspiration and dominant factors (R2 > 0.7, p < 0.01 for all) than the stepwise results for daily averages. A receiver operating characteristic (ROC) curve was applied to validate the division and determine thresholds. All divisions were thoroughly validated, and the soil water storage thresholds of the black locust (120.2 mm and 150.7 mm) were higher than those of the oak (105.8 mm and 137.9 mm). Our results suggest that the oak had an adaptive water consumption strategy, while the black locust had a higher sensitivity to soil water insufficiency. The method for determining the threshold of soil water storage to separate the dominant factors of evapotranspiration was validated. The approach may be applied to other semiarid forest communities with distinct evapotranspiration response patterns.

    Although Chamaecyparis obtusa reduces soil pH and cation levels, limited information is available regarding their alterations after clear-cutting. We examined the soil pH and base cations on the upslopes and downslopes of individual trees and stumps of C. obtusa at two distances (0.5 m and 1.0 m) and three depths (0–5, 5–10, and 10–30 cm) in intact- and cut-tree plots. The soil pH was higher in the cut-tree plot than in the intact-tree plot, indicating the recovery of soil pH after clear-cutting. The recovery was more evident in the surface soils (0–5 cm) of downslope areas (0.5 m) than in other soil depths, which implies that the recovery of soil pH was caused by the lack of H+ supply from stumps after clear-cutting. The results of H+ (in H2O: water-soluble and KCl: exchangeable) suggested a lack of soluble H+ in the cut-tree plot. Soil Ca2+ and Mg2+ levels in the surface soil (0–5 cm) were 1.86-fold and 1.93-fold higher in the cut-tree plot than in the intact-tree plot, respectively, implying that the recovery of divalent cations after clear-cutting was caused by a reduction in cation loss through cation exchange with H+ derived from the stemflow. Collectively, soil pH and divalent cations were recovered after clear-cutting because the stemflow had ceased.

    Forest thinning can significantly affect hydrological processes. However, these effects largely vary with forest types, climate, thinning intensity, and hydrological variables of interest. Understanding these effects and their variations can significantly support thinning treatments' design and selection to ensure desired hydrological benefits. In this global-level review paper, we report the first comprehensive meta-analysis on the effects of thinning on major hydrological processes with an emphasis on rainfall partitioning, soil moisture and evapotranspiration processes. The synthesized and reviewed studies encompass different biophysical conditions (climate and forest ecosystems), silvicultural systems, and time scales (from weeks to decades) across continents. The results showed a significant increase in net precipitation, soil moisture and tree-level water use after thinning (the effect sizes are 1.19, 1.14 and 1.56 relative to the value of the control, respectively), while decreases in stemflow and transpiration (the effect sizes of 0.42 and 0.6 relative to the value of the control, respectively). Thinning intensity of about 50% of the stand density is determined as the threshold at or over which hydrological processes are significantly affected. The duration of thinning effect can be set between 2.6 and 4.3 (throughfall) and 3.1–8.6 years (soil moisture and transpiration), asking for repeated thinning in order to effectively sustain these effects. These global averages can serve as benchmarks for assessment and comparisons, but the effects of thinning depend on local biophysical conditions and thinning treatments. The literature review on the rest of the studied hydrological variables suggests that thinning generally enhance runoff to increase water yield and groundwater recharge. Thinning can also have a positive or limited role in water use efficiency (WUE), but it mitigates the effects of drought through increasing WUE. Moderate adverse effects on water quality can be prevented by adequate forest managements to prevent soil degradation. Nevertheless, more researches at relatively less studied regions are needed to support a more robust analysis of these reviewed hydrological variables. The management implications of the synthesized and reviewed results are suggested and discussed within the context of climate change.

    Interception loss (IL) by the forest canopy removes a substantial quantity of rainwater within forested ecosystems. The large-scale unmanaged Japanese coniferous plantations with high stand density (SD) in Japan raise concerns about an additional increasing IL as a result of a new influential factor of dead branches under canopies. Thus, evaluating the usage of IL estimation models is vital to regulating the water and environment in such coniferous plantations. This study aimed to examine the applicability of the reformulated Gash analytical model (RGAM) to unmanaged coniferous plantations with high SD laden with dead branches. We established two plots (P1 and P2) laden with dead branches under the same SD of 2250 stems ha−1 but with different numbers of dead branches (56 vs. 47 branches per tree) in an unmanaged Japanese coniferous plantation. Results demonstrated that a large difference was found in canopy storage capacity (S) in P1 and P2 (3.94 vs. 3.25 mm), which was influenced by the different number of dead branches; therefore, the IL ratio to gross rainfall differed considerably (32.7% in P1 and 26.7% in P2) regardless of the SD being the same. The difference in S enables the RGAM to reflect the influence of dead branch structures on IL, leading to an acceptable RGAM performance for both P1 and P2 (“fair” IL relative errors: −20.2% vs. −16.1%) in the present study of unmanaged coniferous plantations with high SD laden with dead branches.

    Periodic droughts and extreme rainfall are predicted to become more common in the future; therefore, it is important to understand how soil N transformation processes driven by soil microbes respond to rainfall events. Differences in forest type, including those in the predominant mycorrhizal type, can have varying effects on soil N transformation. Therefore, we hypothesised that the response of the N transformation processes to rainfall events would differ between forest types, even those that are adjacently located. In this study, we generated a soil moisture gradient in adjacent dryland black locust (Robinia pseudoacacia, non-ectomycorrhizal [ECM]-type) and oak (Quercus liaotungensis, ECM-type) forests and measured the abundance and community composition of fungi and prokaryotes (including ammonia-oxidisers), extractable N content, and net N transformation rates in the soil. Increasing moisture was found to increase nitrate N content in the black locust forest but not in the oak forest. In the oak forest, the abundance of ECM fungi increased with increasing moisture, subsequently enhancing ECM fungal ammonium N uptake and limiting the N availability for ammonia oxidisers, which may reduce the nitrate N production by ammonia-oxidisers. Increased nitrate N uptake by ECM fungi may also result in low soil nitrate N content. The findings of this study indicate that the responses of the nitrate N dynamics to rainfall events can differ between adjacent forests and that this difference may be attributable to the presence of ECM fungi. Therefore, considering the forest mycorrhizal type is vital for predicating the response of forest N cycling under climate change.

    Compared to trees, little is known about the respiratory characteristics of bamboo, especially culm respiration. In this study, we measured the respiration rates of current year, 2, 3, and above 4-year-old Moso bamboo (Phyllostachys pubescens) culms and examined its relation to culm morphology and anatomical structure. Current year culms had substantially higher respiration rates (1.9 ± 0.46 μmol m–2 s–1) compared to older culms (2, 3, and above 4-year-old average: 0.17 ± 0.09 μmol m–2 s–1). Culm wood density increased with age, with the concurrent thickening of parenchyma cell walls in the culm tissue. Nitrogen content in the culm tissue decreased with culm age. Both culm wood density and nitrogen content had significant relationships with culm respiration rate. On the other hand, culm height, wall thickness, and circumference did not affect culm respiration rate. Although bamboo culms did not change in size through the year, anatomical changes in the culm tissue that accompanied the aging of a culm affected the respiration. The culm age would have a significant effect on the evaluation of the respiratory characteristics of the bamboo forest. Our results suggested that young culms required a large amount of respiration to grow “inward” as cell wall thickening and also to maintain the relatively large amount of active tissue.

    Black locust (Robinia pseudoacacia) is widely planted throughout semiarid and subhumid regions of the Loess Plateau of China. Determining the changes in transpiration of this species in different climatic areas is important for revealing the acclimation mechanism of black locust and developing suitable forest management practices, particularly in the context of global climate change. Here, sap flow and canopy conductance of black locust plantation trees in semiarid (Yan'an) and subhumid (Yongshou) sites were quantified using Granier-type thermal dissipation probes and concurrent environmental observations from 2012 to 2017. Several physiological parameters were measured throughout the growing season. The results showed that sap flow was correlated with phenological factors across seasons within a year. However, interannual changes in sap flow were affected mainly by the reference evapotranspiration (ET0) at the Yongshou site, and jointly by precipitation (P), soil water content, and P/ET0 at the Yan'an site. Sap flow response to meteorological factors showed less discrepancy between pre- and post-rainfall periods at the Yan'an site. Moreover, canopy conductance fluctuated less with a wider range of vapor pressure deficit (VPD) and the slope of canopy resistance as a function of VPD was lower, indicating relatively lower sensitivity of stomatal conductance to environmental factors in Yan'an site. Physiological parameters, except for predawn leaf water potential, were significantly different between the two sites. The results suggested that black locust tended to reduce transpiration, modify leaf morphology, and improve water use efficiency to enhance its adaptability to the dryer site. The species changes stomatal regulation characteristics and general growth rate to acclimatize to distinct water habitats.

Some reports have investigated the responses in tree transpiration to N addition, but few studies have measured the short-term response of mature tree transpiration to N fertilization. This study aimed to clarify the short-term transpiration response in 27-year-old deciduous hardwood trees to an increase in N availability. We established two plot types (control and N-fertilized plots) in Quercus crispula plantation stands in Hokkaido, Northern Japan. We measured sap flow density (SFD; cm3 m−2 s−1) using a thermal dissipation method for three months during the growing season. In the N-fertilized plot, we added 50 kg N ha−1 yr−1 of ammonium nitrate (NH4NO3) to the forest floor in the middle of the measurement periods. For daily mean SFD, we did not find a significant difference between the control and the N-fertilized plots. Leaf N contents did not differ between treatments, implying a negligible difference in physiological responses and transpiration rates. The slight difference between treatments could be because the trees had already foliated before applying the N fertilizer to our deciduous hardwood trees. The present results indicate that the potential increase in N deposition during the growing season does not immediately alter tree transpiration.

    九州大学農学部附属福岡演習林内のアベマキとミズナラの混交林において、降水量、樹冠通過雨量、樹幹流量の観測を行い、遮断蒸発量を算出した。2012年4月から2013年3月における降水量、樹冠通過雨量、樹幹流量、遮断蒸発量は、それぞれ1661,1226,126,309mmとなり、降水量に対する樹冠通過雨量、樹幹流量、遮断蒸発量(樹冠通過雨率、樹幹流率、遮断蒸発率)は、それぞれ74%、8%、19%となった。本試験地の遮断蒸発率は、これまでの日本の落葉広葉樹林における観測値と同程度であった。これまでに観測された落葉広葉樹林の遮断蒸発率の最大値は、針葉樹林の最大値と比較して小さいことから、遮断蒸発率の大きい針葉樹林を落葉広葉樹林に転換することで遮断蒸発量を減らせる可能性がある。今後は、落葉広葉樹林における遮断蒸発量の観測値をさらに蓄積することで、上述のことを一般化していくことが望まれる。

    Although sap flux measurement is one of the most robust techniques for stand-scale transpiration estimates, its applicability to bamboo is unclear. Ultimately we aim to establish a method for sap flux-based stand-scale transpiration estimates in a bamboo forest This study focused on establishing a method for individual-scale transpiration estimates. We conducted sap flux measurements using hand-made 1-cm length sensors, and water absorption measurements in cut-bamboo. The sensors could detect water uptake in individual plants (i.e., sap flux in moso bamboo). The diurnal changes in sap flux density reasonably well corresponded to those in water absorption. We found there was an underestimation of whole-tree water use with the 1-cm Grainer sensor; thus we suggested a modified equation for the calculation of sap flux density. In this study we could estimate individual-scale transpiration in moso bamboo using sap flux measurements.

    北海道演習林拓北流域及び福岡演習林御手洗水流域において,2005年6月-2006年6月にかけて降水,渓流水を採取・分析し,各流域における大気質や基岩等の立地環境の違いが降水や渓流水の化学成分に及ぼす影響について検討した。拓北流域では,降水,バルク降水,渓流水を採取し,御手洗水流域では,バルク降水,渓流水を採取した。拓北流域では,バルク降水のpH値が降水と比べて高かった。水素イオン以外のイオン成分濃度は,降水と比べてバルク降水で上昇しており,特にCa2+,NH4 +の上昇が顕著であった。このイオン成分濃度の上昇の原因は,無降雨期間におけるガス状,粒子状物質のロート上への乾性沈着によるものと思われた。pH上昇の原因として,乾性沈着によるアルカリ土類金属やアンモニアの溶解が考えられた。バルク降水のNH4 +濃度やNH4 +沈着量は御手洗水流域と比べて拓北流域で高く,NO3 -,SO4 2-沈着量は拓北流域と比べて御手洗水流域で高い結果となり,大気質による違いを反映していた。バルク降水のpHは,御手洗水流域で4.5,拓北流域で5.3であり,御手洗水流域において顕著に低かった。その原因として,御手洗水流域において大気汚染に由来するNO3 -,SO4 2-濃度が高まっていること,拓北流域ではバルク降水中のNH4 +,K+,Ca2+濃度が御手洗水流域よりも高いためと考えられた。渓流水のNO3 -,SO4 2-濃度は,拓北流域と比べて御手洗水流域において顕著に高い値を示した。その原因として,御手洗水流域においてNO3 -,SO4 2-沈着量が拓北流域と比べて高いためと考えられた。また,拓北流域では,K+濃度が高く,御手洗水流域では,pH及びMg2+濃度が顕著に高かった。この違いは基岩の違いが反映していると考えられた。御手洗水流域における渓流水のpHとMg2+濃度には有意な正の相関がみられた。

    本研究では,既往の研究を整理することで,モウソウチク林拡大の実態,現存量を把握すると共に,モウソウチク林の拡大が,林地の水土保全に関する公益的機能を低下させる可能性について検証した。モウソウチク林の面積拡大は数多くの研究により報告されており,年間拡大率の平均は 1.03 ha/(ha year)であった。また,隣接する場所が開けている方が,開けていない場所と比較し,モウソウチク林の拡大速度が大きいことが示唆された。モウソウチク林の地上部現存量は,62.6~224.3 t/ha であり,その最大値はスギ林・ヒノキ林の最大値よりも小さいと予想された。一方,地下部現存量は研究例が少なく,今後のさらなる研究が必要である。林地の水土保全に関する公益的機能について既往の研究成果を取りまとめたところ,これまでの推察に反して,モウソウチク林は,他の森林タイプと比較し,洪水,渇水,表層崩壊,表面侵食のリスクが低いことが示唆された。しかし,この結論は十分な計測例に基づくものではない。今後,様々な林分条件,気象条件のモウソウチク林で数多くの計測が行われ,上記の結論を再検討することが望まれる。

    近年, 水源涵養が, 針葉樹人工林の間伐や広葉樹林化, 竹林の伐採といった森林管理の主要な目的の一つとして位置付けられている。しかし, 森林の水資源量を評価する上で必要な蒸発散量の計測例が不足しており, 森林管理に伴う水資源量の変化は十分には評価できていない。そこで本総説では, 蒸発散量の主要要素である蒸散量の計測を促進するために, 蒸散量計測法の一つである樹液流計測法について, 計測原理や計測時の注意点について取りまとめた。まず, 森林管理に伴う蒸散量の変化を把握する上での樹液流計測法の有効性を他の蒸散量計測法と比較することで示した。次に, 樹液流計測法を用いた場合の単木蒸散量の算出方法, 単木蒸散量から林分蒸散量へのスケーリングアップの方法について既往の研究例を基に説明した。最後に, 今後, どのような森林でより計測を行う必要があるかを論じるために, 国内で樹液流計測法を用いて計測された林分蒸散量を取りまとめた。その結果, カラマツ人工林, 広葉樹林, 竹林では, データの蓄積がほとんど進んでいないこと, スギ・ヒノキ人工林では, 林齢60年以上や20年以下のデータ蓄積が望まれることが明らかとなった。

    近年、豪雨の増加に伴い大規模森林災害が多発し、森林管理は多面的機能の発揮促進から災害に強い森づくりへパラダイムシフトする必要性が検討されるようになってきた。森林では、林内雨は樹冠通過雨および樹幹流という形で林床に到達するが、両要素が森林環境に与える影響は林分構造によって変化する。そこで、針葉樹人工林の林分構造と水循環素過程を総合的に観測し、荒廃針葉樹人工林がどのような形で環境に悪影響を及ぼすのかを明らかにするとともに、得られた観測結果から山地災害や森林環境劣化を軽減する針葉樹人工林の森林管理法を提案する。

    本研究は平成29年7月九州北部豪雨を事例に土砂・流木災害の要因と影響を分析し、森林ゾーニング手法と復興課題を検証した。その結果、20年生以下の林分を起点として山腹崩壊した割合が高く、当地に多いスギ人工林を中心に流木化し、途中で流木が停止しうる地形が乏しかったことが流木流出量を増大させたことを指摘した。また、災害発生から5年間、被害箇所の植生と渓流環境の変化を定点観測し、花崗岩地質で回復が遅れるなど地質によって回復程度が異なること、完全な回復には更に年月を要することを指摘した。社会的には、災害を契機に集落の過疎化の進展がみられるが、景観や文化の再生や創出が災害復興過程に重要であることを示した。

     森林とひとことで言っても、森の中の雨の降り方、林床から土壌中への水の動き、土壌から葉に運ばれ大気に蒸散するまでの樹幹の中の水の流れ、地表や土壌中を流れ河川に流れ出る水等は、樹種、森林の構造、気候等によって大きく異なります。本セミナーでは、針葉樹人工林や広葉樹二次林等を対象に、森林に降った水、水と共に動く物質やエネルギーのゆくえを学びます。
