【摘要】：生态系统服务的空间流动性对流域居民福祉产生了重大影响。本文基于场强理论和断裂点模型构建了流域生态系统服务空间转移模型,以MA的人类福祉框架为基础建立流域居民福祉评价指标体系,运用格兰杰因果关系检验方法及灰色关联模型,以渭干河流域为例,分析了2000-2010年流域生态系统服务价值空间流转及其对居民福祉的影响。结果表明:①流域生态系统服务存在空间溢出效应。渭干河流域上游向下游的生态系统服务流转强度与距离成反比,溢出价值先下降后波动上升。②渭干河流域居民福祉由基本需求、安全与健康、精神三个层次构成,按重要性排序表现为安全与健康基本需求精神需求,并呈现出库车县的福祉水平最高、拜城县其次、沙雅县再次、新和县最低的空间分异特征。③流域生态系统服务空间流转是居民福祉的格兰杰原因,前者对后者产生了较显著的影响,对安全与健康福祉产生的影响最大,上游森林生态系统服务流转与下游居民福祉的耦合度最高,荒漠与居民福祉的耦合度最低。
[Abstract]:Spatial mobility of ecosystem services has a significant impact on the well-being of watershed residents. Based on field strength theory and fracture point model, the spatial transfer model of watershed ecosystem services is constructed in this paper. Based on MA's framework of human welfare, an index system for evaluating the well-being of river basin residents was established. Granger causality test method and grey correlation model were applied to the Weigan River basin as an example. This paper analyzes the spatial circulation of ecosystem service value and its influence on the residents' well-being from 2000 to 2010. The results show that there exists spatial spillover effect on ecosystem service in the basin of 1: 1. The flow of ecosystem services from upper to lower reaches of Weigan River Basin. The rotation intensity is inversely proportional to the distance, The spillover value decreases first and then fluctuates. 2 the well-being of residents in Weigan River basin consists of three levels: basic needs, safety and health, and spirit. It shows that Kuqa County has the highest level of welfare, Baicheng County second, Shaya County again, Xinhe County has the lowest spatial differentiation feature .3 the spatial circulation of ecosystem services is the Granger reason for the residents' well-being. The former had a significant impact on the latter, and had the greatest impact on safety and health, the highest coupling degree between the upstream forest ecosystem service flow and the downstream residents' well-being, and the lowest coupling degree between desert and residents' well-being.
