基于GIS的贵州省县域经济发展环境约束研究

Study on Entironment Restriction of County Region Economy Development Based on GIS in Guizhou Province

借助反距离权重(IDW)空间插值及空间相关分析方法,对贵州省县域经济发展的空间分异特征及自然环境因素与县域经济发展的相关程度及限制作用进行分析。结果表明,贵州省县域经济发展水平在空间上存在较大差异,经济发展水平较高区域主要分布于贵阳、遵义、凯里、铜仁、都匀、兴义等政府所在地,其他县(市)人均GDP水平相对较低;经济发展水平与环境限制因子相关程度各异,其中六盘水、安顺及贵阳地区经济发展水平与环境限制因子关系密切,其他地区相关程度不明显。

This paper analyzed spatial difference feature of Guizhou county region economy, development and environmental factors holding in county region economy development by the ways of inverse distance weight spatial interpolation （IDW） and correlation spatial analysis. The results show that the level of county region economy development in Guizhou has quite differene.The high level of county region economy development loeates in Guiyang, Zunyi, Kaili, Tongren, Duyun and Xingyi area, but GDP per eapita in other counties is low. The correlation degree of the level of economy development and factors of entironment restriction is different in Guizhou which is consanguineous in Liupanshui, Anshun and Guiyang area, and is low in other places.
