- Abstract
The ecological service (ES) of soil and water conservation that is provided by the forest ecosystems in the upper basin of Hunhe river has some movement in certain space, which has an important influence on water supply in Shenyang city in China. From the perspective of forest ES transfer, it works out the ecological service value of transferring in the upstream of Hunhe river towards Shenyang city from 2010 to 2014 with the help of Buffer and Intersect of ArcGIS9.3, and the path analysis is used to explore the impact of the ecological service value (ESV) of transferring in the upstream of Hunhe River Basin on the water supply in Shenyang city. The results demonstrate that firstly total values of transferring from 2010 to 2014 adds up to 5.647 billion RMB, and secondly the ecological service of soil and water conservation has positive external effects on the water supply in Shenyang city by the surface water, groundwater and chemical oxygen demand. It can be seen that it explains the mechanism of action about the impact of transfer value of forest ES in the upper watershed on the water supply in the lower basin, which provides the theoretical foundation to the quantitative analysis of value transferring of forest ES and has an important proof of payment for ecological services of river basin in the theory.
