喀什经济开发区土地利用动态变化分析

根据1977和2012年2期土地利用遥感数据,在GIS空间分析的基础上运用土地利用动态度、土地利用转移矩阵、土地利用重心移动模型研究了1977 ～2012年喀什经济开发区土地利用变化情况,并分析了研究区土地利用变化的原因以及合理性.结果表明,1977～2012年喀什经济开发区园地面积变化率最大,其次是城镇住宅用地面积,耕地、林地的变化速率也较大;草地和地表水资源用地重心向西南方向偏移较大,同时难以利用的荒漠化土地和盐碱地向水资源移动相反的方向偏移,林地和耕地顺水源向南偏移;驱动喀什经济开发区土地利用变化的因素主要是经济因素和人口因素,各种土地利用类型重心的移动方向与城市未来发展具有一致性和合理性,利于未来城市发展以及人民生活.

Dynamic Change of Land Use in Kashi Economic Development Zone

According to land use remote sensing data in 1977 and 2012,on the basis of GIS spatial analysis,the land use changes in Kashi Economic Development Zone during 1977-2012 were studied by using land use dynamic degree,land use transfer matrix,weight shifting model,the causes and rationality for land use change were analyzed.The results showed that during 1977-2012,the change rate of garden area is the maximum,the change rate of urban residential land area,cultivated land and forest land area is also larger; grassland and surface water resource land move towards southwest,the desertification land and saline alkali soil move to opposite direction of water resource,forestland and cultivated land move south towards along water resource; Main driving factors for the land use change in Kashi Economic Development Zone are economic factors and population.The movement direction of each land use type has consistency and rationality with future urban development.
