武汉城市圈土地利用协调度分析

Coordination Degree Analysis of Land Use in Wuhan Metropolitan Area

采用多目标决策方法,结合武汉城市圈土地利用实际情况,构建武汉城市圈土地利用协调度评价模型。分析结果显示:武汉城市圈中大部分城市土地利用协调程度不高,只有武汉和仙桃市属于比较协调范畴,潜江和天门市属于基本协调范畴,鄂州、孝感、黄冈、咸宁市属于不太协调范畴,黄石市属于不协调范畴。土地利用协调度的大小排序为:武汉>仙桃>天门>潜江>咸宁>鄂州>孝感>黄冈>黄石。再通过比较各市环境效益、经济效益、社会效益3个子系统得分高低并结合序参量指标值大小,揭示影响各市土地利用协调度分值高低的原因。最后,对各市未来土地利用提出相关政策建议。

A model of land use coordination degree for Wuhan metropolitan area is created by putting the multi-objective decision- making method into the actual situation of land use in Wuhan metropolitan area. The results show that the coordination degree of land use is not very high in most cities, with Wuhan and Xiantao City on the level of ＂relative coordination＂. Qianjiang and Tianmen are on the level of ＂basic coordination＂, Ezhou, Xiaogan, Huanggang and Xianning on the level of ＂not very coordinated＂, and Huangshi City is on the level of ＂not coordinated＂. By comparing the scores of all the above cities in terms of environmental benefit, economic benefit and social benefit and the order parameter index value in each city, the paper attempts to reveal the reasons affecting the land use coordination degree of each city and offers some policy suggestions for the future land use in each city of Wuhan metropolitan area.
