摘 要:中国城市化进程已经进入加速发展阶段,城镇建设用地规模不断扩大,并已成为耕地面积减少的重要原因。基于成都市1978—2007年30年的统计数据,应用回归分析法和协调度分析法分析了成都市城市化水平和耕地资源的变动情况,城市化水平与耕地变化的相关性,以及城市化水平与耕地资源的协调性。结果表明,30年间成都市城市化水平不断提高,耕地总面积及人均耕地面积都逐年减少;成都市城市化水平与耕地面积变化呈现出显著的负相关关系;城市化水平与耕地面积协调度呈阶段性分布,总体呈现出"调和和基本调和→不协调→调和和基本调和"的趋势。China' s urbanization process has entered a accelerated development stage, the scale of the urban construction site has extended, which was an important cause of the cultivated land has decreased. Author analyzed the changes of the urbanization level and the cultivated land resources, studied the Correlation and coordinated index between the urbanization level and the cultivated land resources of Chengdu city from 1978 to 2007 based on statistical data by methods of regression analysis and coordination analysis.
