摘  要：
[目的]探究浑河流域上游森林生态服务空间流转价值对沈阳市水资源供给量的影响,为制定流域森林生态补偿标准提供科学依据。[方法]以森林生态服务空间流转为视角,借助ArcGIS 9.3软件的Buffer与Intersect分析工具测算出2010—2014年浑河上游向沈阳城市段空间流转的生态服务价值,利用通径分析法,对沈阳城市段水资源供给量的影响展开研究。[结果]2010—2014年浑河流域上游向沈阳城市段空间转移的总价值为56.47亿元;上游森林水源涵养与保持水土的生态服务通过地表水、地下水与化学需氧量共同作用于沈阳城市段供水量。[结论]浑河流域上游森林生态服务空间流转价值产生正外部效应,对沈阳城市段供水量影响是由多个因素直接作用、间接作用共同决定的结果。

摘  要：
[Objective]The aim of study was to analyze the effects of forest ecological service value transfer from upstream in Hunhe River basin on water supply in Shenyang City cluster,which might contribute to make forest ecological compensation standard of the river basin.[Methods]From the perspective of forest ecological service transfer,forest ecological service value transfered from upstream were calculated with ArcGIS 9.3 buffer and overlay analysis platform from 2010 to 2014,and then it studies the effects of forest ecological service on water supply in Shenyang City cluster were studied using the path analysis.[Results]Forest ecological service value transfered from the upstream in Hunhe River basin reached 5.647 billion RMB from 2010 to 2014.Forest ecological service of the water conservation and the soil conservation in the upstream had impacted on the water supply in Shenyang City cluster by surface water,groundwater and chemical oxygen demand(COD).[Conclusion]Forest ecological service value transfer in the upstream generates positive externality,which comprehensively influences on the water supply in Shenyang City cluster by direct effect and indirect effect from multiple factors.
