武汉“1+8”城市圈土地利用动态变化研究

Research on Dynamic Change of Land Use in ‘1+8' Wuhan Metropolitan Area

利用武汉城市圈内9个城市1997—2006年土地利用变化数据,采用土地利用动态变化方法中的土地资源数量变化模型、土地利用程度变化模型、土地利用区域变化差异模型来分析武汉城市圈1997—2006年土地利用变化的情况。研究表明,土地利用动态分析能够很好的揭示城市圈土地利用结构特征的变化规律;武汉城市圈中,武汉市综合土地利用动态度为0.76%/年,远高于其他八个地区;土地利用程度变化方面,增加最多的武汉市土地利用程度指数变化量为0.463,而咸宁市土地利用程度指数减小了0.609,是减少最多的地区;土地利用类型相对变化方面,耕地变化主要集中在武汉市、黄冈市和咸宁市,园地变化集中在武汉市和孝感市,交通用地变化则集中在武汉市、孝感市和咸宁市。根据研究结果,文章提出了对策建议。

According to the data of land use in nine cities of Wuhan metropolitan from 1997—2006,land use change was analyzed by land resources quantity change model,land use degree change model and land use change regional diversity model.Research showed that analysis of dynamic change of land use specifically revealed the changing regularity of land use structure in metropolitan area;in Wuhan metropolitan area,Wuhan City＇s dynamic degree of general land use was 0.76% per year,was much higher than other 8 cities;Wuhan City＇s index of land use increased 0.463,but Xianning＇s index decreased 0.609,they were the city seeing biggest increase and biggest decrease respectively;farmland change mainly happened in Wuhan City,Huanggang City and Xianning City;garden land change mainly happened in Wuhan City and Xiaogan City;land for traffic change mainly happened in Wuhan City,Xiaogan City and Xianning City.Finally,policy suggestion were proposed according to results.
