摘要：为确定区域内生态扩散与接收区域范围,采用双变量空间分析的方法,对长江经济带城市群各地级市的自身用地结构及其周边经济环境进行分析,提取出异常区域并进行叠加分析,划分土地利用生态效应的扩散或接收中心。研究结果表明,各地级市不同的用地结构对于周边城市经济具有一定的影响,其中城镇化用地、农业用地具有带动周边经济的作用,生态用地具有滞缓周边经济的作用;城镇化区划分比例高且周边经济发展水平较高的区域是主要的生态需求区域;生态用地划分比例较高且周边经济发展水平较高的区域是主要的生态扩散区域。
In order to determine ecological diffusion range and reception range of cities around Yangtze River economic belt,bivariate spatial analysis method was applied to analyze the land use structure and economic environment.Overlay analysis was conducted on abnormal areas extracted and these areas were divided into the diffusion center or reception center of the ecological effects caused by land use.The results showed that land use structure had certain impacts on surrounding cities.The urban land and agricultural land had a positive effect on economic development,while ecological land displayed a negative effect on economic development.The area of high urbanization and economic development was the main region for ecological demand,while the area of high ecology and economic development was the main region for ecological diffusion.
