| 摘 要： | 随着科学技术的发展，遥感技术运用到土地利用管理中，能够快速提取土地利用变化信息，同时地理信息技术（GIS）迅猛发展，基于这两种技术结合起来探测土地资源的变化具有重要的现实意义。因此，在GIS平台支持下，将土地利用变化分析结果用于土地利用更新从而得到更新后的土地利用现状图。并根据土地利用面积变化、类型等方面对项目区进行了定性定量研究。根据土地利用变化情况以及土地利用各类型之间的相互转换状况，建立了土地利用类型转换矩阵并根据项目区实际情况提出了在石漠化地区生态效益恢复的建议及对策。

| Abstract: | Applying remote sensing （RS） technology to management of land use can mine the information on the dynamics and changes of land use more effectively and quickly than the other traditional methods, which is of practically great importance to the management of the land resource. In this paper, regional land use changes were analyzed by the RS technology associated with and geographical information systems （GIS） with aim to illustrate the updated land-use maps. Furthermore, the aspects such as area and type of land use changes would be discussed qualitatively or quantitatively. Meanwhile, a land use conversion matrix was established based on the dynamic changes and the conversion scopes of the various types of land use. In accordance with the results obtained above, relevant recommendations and strategies on ecological recovery in the Rocky desertification area was also put for-ward in the end of the paper. |
