稳定而又良好的水源涵养量是维持区域生态环境稳定、实现生态保护可持续发展的重要基础。迄今为止，国内开展水源涵养功能监测与评估主要涉及森林生态系统和不同土壤特性下的水源涵养量的计算，有关省域尺度的水源涵养量变化监测研究相对较少。因此，本文选取江西省作为研究区，采用降水贮存量法结合遥感技术，基于研究区降水量和植被度指数数据，监测分析研究区水源涵养量在2010－2015年间的时空变化情况。结果显示，2010－2015年间，江西省水源涵养量的整体格局基本保持稳定，整体略有小幅降低。%Stable and good water conservation is an important foundation for maintaining regional ecological stability and achieving sustainable development. So far, monitoring and assessment of water conservation in China has mainly involved the calculation of water conservation in forest ecosystems and different soil properties. There are relatively few studies in the monitoring of water resources conservation in provincial scale. Therefore, this paper selected Jiangxi Province as the study area, based on the precipitation and vegetation index data of the study area, used precipitation storage method and remote sensing technology to monitor and analyze the spatial and temporal changes of the water conservation capacity in the study area in 2010-2015. The results showed that the overall pattern of water conservation in Jiangxi Province was basically stable in 2010-2015, and the overall trend was slightly decreased.
