| 摘 要： | 喀斯特石漠化是在喀斯特脆弱生态环境下，人类不合理的社会经济活动而造成人地矛盾突出，植被破坏、水土流失、土地生产力衰退丧失，地表呈现类似荒漠景观的岩石逐渐裸露的演变过程。贵州喀斯特地区受人类活动影响，特别是由于土地资源利用的不合理，不同区域出现了一系列的环境问题，一些地区存在的石漠化现象表现得尤为突出。清镇市地处贵州黔中地带，是喀斯特发育较完备的地区之一,其中碳酸盐岩面积占全区总面积的67.96%，喀斯特面积占绝大部分。通过应用多波段、多平台的遥感信息，在野外调研基础上与GIS技术支持下，对图件进行解译、编辑处理，制作清镇石漠化动态图，为贵州喀斯特地区生态治理及环境建设等方面提供依据。

| Abstract: | Rock desertification is an evolving process that human beings contradict with land, that is caused by the unreasonable social and economic activities of human beings, which lead vegetation to be destroyed, soil to be washed away and land productive power to be reduced even lost under the weak ecological environment of karst. The karst region in Guizhou is affected by human's activities. Especially in different areas, a series of problems arise, due to the irrational exploitation of soil resources. Qingzhen, located at the center of Guizhou province, is one of the typical karst areas. Carbonate rocks account for 67.96 percentage in Qingzhen, and most of them are karst. Applying to Remote Sensing information of multi_spectral, multi_platform, basing on the research outside and supported by GIS, the authors analyzed and reorganized the data and diagrams and drew the Dynamic Rock Desertification Diagram of Qingzhen in order to supply grounds to ecological treatment of karst region and environmental construction in Guizhou province. |
