| 摘 要： | 在总结了目前使用较广泛的土地利用类型动态度模型的基础上，提出了转出速度、转入速度、综合动态度、状态指数等模型，并指出唯有将这些模型综合运用，才能更好地理解土地利用动态变化。应用遥感和GIS技术及数理统计学的方法，运用建立的模型以及LUCC的幅度、区域差异模型，深入而全面的研究了三峡工程实施十年间开县LUCC的过程。 |

| Abstract: | The authors firstly sum up the dynamic models of land use types that are widely used at present and establish mathematical models which are the output speed, the input speed, the synthetical dynamic velocity. At the same time, it points out these mathematical models must be used synthetically in order to catch on dynamic change of land use. In combination with the methods of RS, GIS and Statistics, the process and trend of LUCC in Kaixian are thoroughly studied by models established as well as the models that are the range and regional differences of LUCC. |
| Keywords: | Three Gorges Reservoir Area land use/cover change rs gis temporal and spatial variation |
