贵州省贫困发生率与生态系统服务价值相关性分析

Correlation Analysis Between Poverty Incidence and Ecosystem Service Value in Guizhou Province

为探究贫困水平与生态系统服务价值(ESV)的相关性。基于2010年贵州省土地利用和贫困发生率数据,利用GoeDa模型和ArcGIS软件探究了贫困发生率与ESV的空间相关性。结果表明:贫困发生率与ESV之间存在正相关性,贫困发生率较大的地区ESV越高。贫困发生率与地均ESV的Moran指数大于贫困发生率与生态系统服务总价值(TESV)的Moran指数。贵州省东南部呈高—高相关,中部呈低—低相关,西部呈高—低相关。社会经济发展水平与土地利用结构空间格局的差异是造成贫困发生率与ESV空间关系不同的主要原因。

In order to explore the correlation of poverty levels and ecosystem service value（ESV）,we analyzed the spatial correlation between poverty incidence and ESV based on the data of land use and the poverty incidence in Guizhou Province in 2010 by using the GoeDa model and ArcGIS software.The results showed that there was the positive correlation between poverty incidence and ESV.High value of poverty incidence had higher ESV.Moran index between poverty incidence and average ESV was higher than Moran index between poverty incidence and total ecosystem service value（TESV）.High—high correlation was found in southeast part.Low—low correlation was observed in middle part.High—low correlation existed in west part.The different spatial patterns of social-economic level and land use structure are the main reasons for resulting in the different spatial correlation between poverty incidence and ESV.
