摘要
为考察城市群的资源协调利用状况,在界定土地集约利用与生态经济协调发展内涵的基础上,基于数据包络分析模型与纵横向拉开档次法,运用逼近理想解排序法构建了协调性测度模型,分析了成渝城市群协调发展水平的时空分异特征。结果显示:成渝城市群的协调发展趋势与区域生态效率变化一致,二者呈现相互促进的正相关关系,但协调发展状况与城市土地集约利用水平的变化不一致;成渝城市群土地利用与生态经济之间的协调发展状况总体上呈现下降的趋势;样本期内,成都、达州、资阳三地的协调水平较高,眉山、乐山的协调水平较低。据此认为,成渝城市群区域生态效率的改善是城市土地集约利用的必要条件,二者的协调发展必须以改善生态环境为前提,并且应建立环境友好型土地利用模式,促进成渝城市群土地的集约利用。
Based on the defining to the coordinated development of intensive land use and ecological economy in urban agglomeration,the eco-efficiency and intensive land utilization level is measured by DEA Model and Vertical and Horizontal Scatter Degree Method in Chengdu-Chongqing Urban Agglomeration. The results show that the tendency of coordinated development of urban agglomeration is in accordance with the change of ecological efficiency,which presents a positive correlation of mutual promotion,meanwhile,they are not consistent with each other; the development situation of intensive land using and ecological economy development presents a decreasing trend generally in Chengdu-Chongqing Urban Agglomeration. The coordination level of Chengdu,Dazhou and Ziyang is higher while Meishan and Leshan lower. The results above show that the improvement of ecological efficiency of Chengdu-Chongqing Urban Agglomeration is a requirement for land intensive use and their coordinated development is a precondition to the enhancing of ecological environment through an environment-friendly land using pattern to improve the land using.
