JapanFlux2024 RU-Ege Elgeeii forest station

This study investigated evapotranspiration and CO2 exchange, observed by the eddy covariance method, over two larch-dominated forests, in the middle part of the Lena basin, eastern Siberia. Two observation sites in larch-dominated forests in the middle parts of the Lena basin were selected for this study. The first was the Elgeeii (EG) station on the Aldan River, which is a branch of the Lena River, located 300 km south-east of Yakutsk. The other was the SP station located near Yakutsk. The dominant species in both forests are larch (Larix cajanderi), mixed with mainly willow (Salix bebbiana) at EG and birch (Betula pendula) at SP. Birch and willow are the third dominant species at EG and SP, respectively. At EG, the forest partly consisted of young pines (Pinus sylvestris).本研究针对东西伯利亚勒拿河盆地中部的两处以落叶松为优势种的森林，采用涡度协方差法（eddy covariance method）观测其蒸散与二氧化碳交换过程。本研究选取勒拿河盆地中部两处落叶松优势林作为观测站点：其一为位于勒拿河支流阿尔丹河沿岸的埃尔吉（Elgeeii，EG）站，该站地处雅库茨克东南300公里处；其二为紧邻雅库茨克周边的SP站。两处森林的优势树种均为落叶松（Larix cajanderi），其中EG站的伴生树种以柳树（Salix bebbiana）为主，SP站则以垂枝桦（Betula pendula）为主；柳树与垂枝桦分别为EG站与SP站的第三优势树种。此外，EG站的林分中还包含部分幼年松树（Pinus sylvestris）。
