摘要
该文以重庆市沙坪坝区为研究区域,借助Geo SOS平台,采用2004、2006年的土地利用、道路、镇政府点、高程数据,利用基于Logistic—CA模型方法对土地利用变化进行模拟研究。结果显示,CA模型模拟土地利用变化与实际土地利用类型面积相差不大,具有较高精度。在城市规划与区域发展情景和生态环境保护管理情景2种管理情景下,未来的重庆市沙坪坝区城市建设用地将持续增加,城市建设用地对具有重要生态功能的林地威胁较小,但对非基本农田之外的耕地或农田占用较多。
Shapingba District, Chongqing City is chose as the study area, by basing on GeuSOS platform, using the 2004, 2006 land use, rnads, dnwnlnwn point and elevation data, Logistic-CA was adopted to simulate land use ehange. The results showed, in urban planning and re- gional development and ecological environment protection management situation of two scenario, the future of urban cnnstruction land in Shaping- ba District, Chongqing City will increase continuously, urban construction land has less threatened the importanl ceological function of forest land, large amount of the cultivsted land or farmland ouiside of basic tarmland will be occupied.
