贵州省生态系统服务价值与社会经济空间相关性分析

Spatial Correlation of Socioeconomic Factors and Ecosystem Service Values in Guizhou Province

基于2000年,2010年土地利用与社会经济数据,利用GeoDA模型分析了贵州省生态系统服务价值(ESV)与城镇化率、人均GDP、人口密度之间空间相关性。结果表明:2000年和2010年ESV与城镇化率、人均GDP、人口密度呈负相关;10a间,ESV变化与城镇化率变化、人均GDP变化呈正相关,与人口密度变化呈负相关。ESV与城镇化率、人均GDP、人口密度之间高—低相关多分布中部,低—高相关多分布东南部和西北部,低—低和高—高相关分布较少且分散。ESV变化与城镇化率、人均GDP变化之间低—高相关和高—高相关分布北部和西北部,低—低相关分布中部。ESV变化与人口密度变化之间高—低相关分布中部,低—高相关和高—高相关分布北部和西北部。

Based on the data of land use, social economy for 2000 and 2010, we explored the spatial correlation of urbanization rate, GDP per person, population density and ecosystem service value （ESV） in Guizhou Province using the GeoDA model. The results showed that there was a negative correlation between urbanization rate, GDP per person, population density and ESV. A positive correlation between urbanization rate change, GDP per person change and ESV change could be observed, while a negative correlation between ESV change and popula tion density change could be found. The high-low correlation and low high correlation mainly occurred in central part, southeast and northwest parts, while there were little high high correlation and low low correlation in spatial correlation types of urbanization rate, GDP per person, population density and ESV. The low high correlation and high high correlation were situated in north and northwest parts, while low low cor relation was observed in central part between urhanization rate change, GDP per person change and ESV change. The high low correlation lied in central part, while high low correlation and low high correlation mainly presented in north and northwest parts between population density change and ESV change.
