Abstract

Water conservation is one of the ecological service functions of terrestrial ecosystem, which is of great significance for monitoring and protecting the ecological environment. The area with Danjiangkou reservoir as the core is an important ecological service function area of water conservation in China. Aimed at the distribution and dynamic change of water conservation function in this region, this paper inverses the regional water conservation capacity based on the water balance principle in 2015 and 2020, also studies the spatial difference and interannual variation in combination with the changes of land use, precipitation and temperature. The results show that the type of land use plays a decisive role for the maintaining and improving of regional water conservation, and the climatic conditions such as precipitation and temperature have a great impact on the fluctuation of water conservation capacity.
