Analysis of ecosystem function of taiga in eastern Siberia

对东西伯利亚针叶林和针叶林-苔原边界的水、碳和氮循环进行了实地观测。针叶林研究地点的土壤湿度水当量是根据落叶松树轮 13C 重建的 100 年来的土壤湿度水当量。我们的观测结果表明，2006-2007年的湿润状况属于极端事件，这一时期全年都有从该地区流向勒拿河的径流。在落叶松林中也观察到氮动态。土壤无机氮库大小随土壤温度的变化表现出很大的季节性。

Field observations were carried out on water, carbon, and nitrogen cycles in taiga and taiga-tundra boundary in eastern Siberia. Soil moisture water equivalent at taiga forest study site was reconstructed for pas 100 years from tree-ring 13C of larch. Our observational results showed that the wet condition in 2006-2007 was extreme event, and runoff from the region to Lena river was generated for a whole year during this period. N dynamics was also observed in larch forest. Soil inorganic N pool size showed large seasonality depending on the soil temperature.
