気候変動の影響を直接的・間接的に受け、降水量や気温の極端現象の激化や頻発化に直面している寒冷圏陸域生態系では、今後も永久凍土荒廃・後退が進行すること懸念されている。従来から注目されている火災や森林伐採などの攪乱に加えて、都市活動にともなう土地利用変化の影響もその要因の一つである。土地利用変化が凍土環境およびその安定性に及ぼす影響を最小限に抑える対策につながる知見を得ることを目的として、本研究では永久凍土地帯東シベリア森林域にある都市周縁域における、利用形態や攪乱程度の異なる植生地の凍土保護機能を地表被覆の断熱効果に着目して評価する。
本課題は、気候変動の影響に加えて人間活動による永久凍土の荒廃・後退が懸念されている東シベリア森林地域の都市周縁域における、都市的土地利用および攪乱程度の異なる植生地の凍土保護機能を地表被覆の断熱効果の評価を通して、凍土への影響を最小限に抑えて必要な都市活動を維持する凍土保全策の探求を目的とする。2020年度は、以下の２点を中心とした成果が得られた。
１）対象地域の凍土植生情報とそれに影響を及ぼす土地利用について、文献とロシアの共同研究者からの情報収集に基づき調査した。凍土活動層の熱収支に影響を及ぼす植生被覆の季節動態およびその年変動について、（英語化されていない）ロシアの研究成果をもとに、対象地域の森林を中心にの立地や遷移段階の異なる植生地における、活動層の凍結融解過程の情報を整理した。また、森林での人間活動のうち植物採取に注目し、対象地域での採取活動に関する社会状況等を、文献や行政資料、現地研究者からの情報収集により調査した。
２）人為影響の小さい森林として比較対象とするサイトにおいて、これまでに得られている地温データの解析より、地表植生の変化のある過去20年では、植生変化による地表断熱効果に加えて土壌水分の変動が活動層の融解凍結過程の年変動と関係することがわかった。温度計測に基づく地表断熱効果の評価は、被覆厚と測定深度の関係に不確実性が残り検討が必要であるが、年変動をとらえるには適していると考えられる。来年度以降に実施可能であれば、人間活動の影響のある植生地においても、活動層地温の観測を行い比較する。このための計測機器の準備をおこなった。
ロシアでの現地調査と観測機材の輸送ができないことにより、申請時の年次計画に記した項目は実施できていない。研究期間内にも状況の変化が期待できないため、現地調査を中心とする実施内容を変更する必要があると判断した。
今年度も現地調査を実施する見通しが立たないため、引き続き，文献と現地共同研究者からの情報収集により対象地域の凍土・植生情報と凍土保全対策等の状況を調査する。来年度の渡航可能性を考慮しながら、現地共同研究者と実現可能な調査計画を検討し準備する。

The interaction between forest ecosystem and atmosphere in eastern Siberian was investigated, using the ground observation and the atmospheric profile data for the last two decades. The seasonal and interannual variations of the surface heat balance and parameters of the atmospheric boundary layer were presented. Based on these results, interannual variation of the seasonal transition factors, including snow melt, plant phenology and seasonal thawing process in the permafrost active layer, and effects of the unusually wet condition in the active layer in the 2000s were discussed.
Influences of forest evapotranspration and photosynthesis under the humidification in the Lena river basin, eastern Siberia

In the Lena river basin of eastern Siberia, the characteristics of forest evapotransriration and photosythesis are changed by forest environmants in waterlogging durings 2005-2008, and the influences of damages for waterlogging are studied in forest physiology (A), forest ecology (B), permafrostlogy (C), and river hydrology (D).
The influences of the responses for the A, B, and C processes were appeared by the charactrestics of forests, and the evapotranspiration and photosynthesis are decreased by permafrost conditions in the waterlogging. The influences for the D response was not issued at all and was not changed by forest conditions in the waterlogging period. This phenomena is considered in the place of occurrence for the river discharge.
The influences of the responses for the smaller or the bigger groupes are appeared by evapotranspiration, photosynthesis, and permafrost characteristics.

This research project clarified spatial and temporal variations in degradation processes in permafrost region in eastern Eurasia, based on comprehensive analyses utilizing field work for vegetation-permafrost relationship, leveling on active layer and topographical change along permafrost degradation combining remote sensing technics, permafrost hydrological analyses and improved land-surface modeling. Notable results are summarized as follows. Spatial variation in active layer thickness was closely related with vegetation changes. Spatial structure of thermokarst development precisely mapped along with vegetation and active layer conditions. The permafrost degradation was also found in water-resource form geochemical composition in spring water. Based on these findings from field work, effect of snow depth, soil organic and moss layer in land surface model were sufficiently improved the performance to simulate permafrost temperature and active layer thickness in this region.

Field observation data of heat flux to atmosphere from vegetation and satellite data of land surface is used in order to evaluate effect of vegetation on urban atmospheric heat environment. Temperature difference between urban surface (without vegetation) and various urban vegetation such as park, agriculture field, and suburban forest is investigated with focus on multi-scale temporal variation (daily, seasonal, and inter-annual). Although vegetation field is generally cooler than urban surface, some exception is observed as follows; surface temperature is warmer in agriculture field during wintertime and occasionally heat flux from forest surface is compatible to those of urban surface even in summertime. If we miss to consider vegetation types and composites of urban vegetation field, we should overestimate cooling effect of vegetation.
The universality and the diversity on Water/Energy/Carbon exchanges of forests in East Asia
Grant number：20248016 2008 - 2011

The water, energy and carbon(W/E/C) exchanges from tropical to boreal forests through temperate forests in the Eastern Asia are examined from the tree levels to the forest levels with the observations and modelings. The forests environments, especially in winter, are severer in the high latitudes than in the low latitudes. And the responses of individual trees in the tropic, the temperate and the boreal zones are different each others, but those of stands scales are equal to several potential lines between the environment conditions and the conductance of the forests. The several models can be possible to represent the W/E/C cycles basically, but the soil water supply in the deeper parts of the soil layers is needed to add in the tropical forests.
