JapanFlux2024 JP-MBF Moshiri Birch Forest Site

The Uryu Research Forest is located in the uppermost reaches of the Uryu River in the Ishikari River system and covers an area of approximately 25,000 ha. It is one of the coldest areas in Hokkaido. The northern part of the forest, surrounding Lake Shumarinai, the largest man-made lake in Japan, is a gently sloping andesite-based mountainous area with a diverse forest cover including Quercus serrata forests, wetland red spruce forests, and riparian forests, centered on naturally occurring mixed forests. In the southern part, on the other hand, there are many mountainside slopes composed of serpentinite and metamorphic rocks, and natural forests of red spruce that depend on these geological features are distributed, while secondary forests resulting from forest fires and clear cutting cover a large area. The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system.

雨龙研究林（Uryu Research Forest）坐落于石狩水系（Ishikari River system）雨龙河的上游流域，总面积约25000公顷，是北海道气候最为寒冷的区域之一。其北部环绕着日本最大的人工湖朱鞠内湖（Lake Shumarinai），该区域为以安山岩（andesite）为基底的缓坡山地，森林覆盖类型丰富多样，以天然混交林为主体，涵盖枹栎林（Quercus serrata forests）、湿地红云杉林与河岸林。研究林南部则多为由蛇纹岩（serpentinite）与变质岩（metamorphic rocks）构成的山坡，依托此类地质特征生长的红云杉天然林广泛分布，而由森林火灾与皆伐（clear cutting）形成的次生林亦占据了大面积区域。本研究采用涡度协方差系统（eddy covariance system）对感热通量、潜热通量及二氧化碳（CO₂）湍流通量进行了观测。

背景概述

该数据集是JapanFlux2024项目的一部分，聚焦于日本北海道Uryu研究森林的Moshiri桦树林地站点，利用涡动协方差系统长期测量感热、潜热和CO2通量，时间跨度为2003年至2011年，旨在支持东亚地区生态系统通量观测研究。
