黔桂岩溶山区土地利用冲突强度演变及其空间分异特征
Evolution and spatial variation of land use conflict intensity in Qian-Gui karst mountainous areas
摘要
Abstract
In this paper,we both use land conflict model based on PSR (Press-State-Response) to assess the evolution of land use conflict intensity and explore the change of spatial differences of land use conflict intensity at a county level and use ESDA (Exploratory Spatial Data Analysis) method for the years from 1990 to 2010 in Qian-Gui karst mountainous areas.As the results,(1) From 1990 to 2010,the phenomenon of land use conflict had increased in Qian-Gui karst mountainous areas because LUCI(Land Use Conflict Index)rose from 0.09 to 0.30;(2) In the study region,the global spatial autocorrelation of land use conflict had a significant agglomeration characteristic which appeared an enhanced trend.In addition,the global Moran's I of the Press Index,the Response Index and LUCI were respectively 0.3179,0.4733 and 0.1859 in phase Ⅲ.Particularly,the global Moran's I in phase Ⅱ was greater than that of phase Ⅰ;(3) In terms of local spatial autocorrelation,it is noted that the hotspots and sub-hotspots tended to agglomerate into city clusters which is located in Guiyang,Central Guizhou Province and Nanning City,Guangxi Zhuang Autonomous Region and its surrounding areas.However,cold spots and sub-cold spots collectively distributed in remote Qian-Gui karst peak-cluster depression areas and their surrounding districts.From the results,it is necessary to optimize the land use structure and alleviate the land use conflict,in order to improve the level of sustainable utilization of land resources.关键词
