水生态系统服务功能变化的驱动因子分析——以三工河流域为例

Driving Forces of the Aquatic Ecosystem Services Function——A Case of Sangonghe Watershed

以新疆三工河流域为研究对象,分析了影响该流域水生生态系统服务功能的变化的驱动因子。研究表明,人类活动是最主要的影响因素,尤其是土地利用变化对水生生态系统的影响最为深刻,是水生态系统服务功能变化的主要驱动因子。

The aquatic ecosystem services function is mainly made up of provision,supporting,regulating and aesthetic function,and it is determined by water quantity,water quality and aquatic life and so on.In the case study of the Sangonghe watershed,changes and the corresponding driving forces of aquatic ecosystem services function have been investigated.The results have shown that human activities,especially land use change, have great impacts on the ecosystem,while the ecological impacts of natural forces were quite uncertain.In order to reduce the exploitation and the use and protect the aquatic ecosystem from destroying,and provide the residents service function,the land use especially the exploitation of plantation should be restricted and the object of the agriculture development should be determined by the water resources.
