摘要
在遥感和GIS技术支持下,定量分析研究区1989～2003年的土地利用/土地覆盖变化过程,以及土地利用/土地覆盖变化各类型之间的相互转化状况,并定性分析研究区土地利用/土地覆盖变化的驱动因子。运用马尔柯夫模型,对研究区未来土地利用/土地覆盖演变趋势进行模拟与预测。为实现研究区土地资源的可持续利用,必须在提高全民环保意识、坚决贯彻国家相应法律法规的前提下,加强天然林保护,建立长期有效的补偿机制,搞好退耕还林还草,严格控制人口增长。
Based on RS ＆ GIS technology, the evolution process and the transformation of each other among all types of land use/land cover change, from 1989 to 2003, were analyzed quantitatively in the study area. At the same time, the driving factors about the land use/land cover change were discussed and the evolution tendency of land use/land cover in the future was simulated and predicted with Markov model. Finally, some advices were given by the author in order to realize the sustained use of the land resources in Shangri-la County.
