摘要
通过构建城镇化与生态环境协调发展指标体系,采用PLSPM模型与复数据表结合计算协调发展评估指数,寻找影响二者协调发展的主要因素,同时利用灰色关联度模型分析了区域间城镇化与生态环境协调度的空间分布特征及演变规律.结果表明:综合发展水平显示出不同区域间呈现明显的地理差异,沿海地区城镇化快速发展产生的空间压力和生态压力逐渐增大,需调整空间城镇化布局与优化资源利用方式缓解城镇化发展带来的生态环境压力;协调发展度呈现华东>华北>中南>东北>西南>西北的逐渐递减空间分布特征,具有显著空间差异性.
Through constructing the indicators of urbanization and eco-environment coordinated development,PLSPM model and Complex data table were used to compute the coordinate development index and some main impact factors were found.Also,the gray relative model was used to analyze the spatial-temporal feature and evolution rule of urbanization and eco-environment coordinated development among every district.The results show that:The comprehensive development level showed obvious geographical differences,and the spatial pressure and ecological pressure generated by the rapid development of urbanization in coastal areas are increasing,which needs to adjust the layout of space urbanization and optimize the way of resource utilization to alleviate the pressure of ecological environment brought by urbanization;The coordinated development degree showed the gradually decreasing spatial distribution characteristics of East China>North China>Central South>Northeast>Southwest>Northwest in China.
