Ecosystem Service Transfer And Its Influence On Human Well-being In Weigan River Basin

Taking Weigan River basin as an example, ecosystem service value(ESV) transfer assessment model is built according to the theory of field strength and the breaking point model. The ESV and its transfer between upstream and downstream from 2000 to 2010 are calculated. The indicator system of human well-being is established by considering nature- social- economic conditions as well as data availability in Weigan River basin. Eviews8.0 Granger causality test method and the grey correlation model are introduced to analyze how the ecosystem service transfer influence on human well-beings in Weigan River basin. The results show that:(1) On the spatial dimension, the upstream to the downstream transfer intensity of ecosystem service value is inversely proportional to the distance from upstream. On the time dimension, upstream has a strongly impact on the downstream. These provide the basis for eco-compensation in Weigan River basin.(2)The indicators system of human well-being constituted with three levels like basic requirements, safety and health and spirit need whose importance can be ranked as the safety and health > the basic demand > the spirit. And the well-being of Kuqa is the highest, Baicheng the second, Xinhe is the lowest level in space differentiation rule.(3)At 0.1 significant level, ecosystem service transfer is the Granger reason of human well-being. Ecosystem services transfer is the cause of the human well-beings’ increase or reduce. Combined with ecosystem function analysis and residents income level changes, ecosystem service transfer has a great influence on basin human well-being in study area.(4)Ecosystem service transfer has an enormous impact on the safety and health in the indicators system. Among them, the ecosystem services transfer of forest has the highest coupling degree with human well-being. Coupling degree between the desert and human well-being is the lowest. The research primarily reveals how ecosystem service transfer influence on human well-beings, and also provides support for eco-compensation between upstream and downstream in Weigan River basin.
