摘要: 云南地处我国西南边陲,是全国岩溶分布最广和石漠化严重省区之一,石漠化面积在不断扩张,生态环境在逐步恶化,亟需采用遥感技术对石漠化进行快速监测。在野外实地调查的基础上,通过遥感技术对滇东南岩溶山区的岩溶地貌、区域断裂构造及岩性分布等地质环境特性进行探测与分析,剖析了研究区岩溶石漠化与
地质环境的相互关系———岩溶地貌类型与石漠化程度有明显的相关性,严重石漠化现象多发生于峰丛洼地与峰林洼地,无石漠化与潜在石漠化区域多处于岩溶山地、岩溶槽谷与岩溶平原,在岩溶丘陵与岩溶盆地中存在一些轻度和中度石漠化现象;区域断裂构造对石漠化的发育空间与分布区域有重要影响,石漠化严重的区域主要集中于红河断裂、开远—丘北断裂与广南—富宁断裂包围的区域,在小江断裂和弥勒—罗平断裂中间地区也存在着一些连片状的石漠化区域,小江断裂以西的地区多为无石漠化区域;岩性类型对石漠化的空间分布格局起着显著的控制作用,无石漠化与潜在石漠化多分布于非碳酸盐岩地区,石漠化主要集中于碳酸盐岩地区,在纯灰岩地区石漠化现象严重,多为强度和中度石漠化区。

Abstract: Abstract:Yunnan is located in the southwestern border of China.It is one of the prowinces with the most extensive karst distribution and severe rocky desertification in China.The area of rocky desertification is conlinuously expanding and the ecological environment is gradually deleriorating. It is urgent to use remote sensing technology to quickly monitor rocky desertification.On the basis of field investigations,the remote sensing technology was used to delect and analyze the karst landforms,regonal fault sluctures and lithological distribution of karst mountainous areas in southeasterm Yunnan,and to analyze the relationship between karst rock desertification and geological environment in the study area.The types of karst landforms have obvious correlation with the degree of rocky desertification.Severe rocky desertification mostly occurs in the peak cluster depressions and peak forest depressions. The areas without rocky desertification and potential rocky desertification are mostly located in karst mountains and karst trough valleys.Like karst plains,there are some mild and moderate rocky desertification in karst hills and karst basins and regional fault structures have an important impact on the development space and distribution area of rocky desertification,and areas with severe rocky desertification are mainly concentrated in the Red River,Kaiyuan-Qiubei fault and Guangnan-Funing fault. There are also some continuous rocky desertification areas in the middle of the Xiaojiang fault and the Mile-Luoping fault, and the west of the Xiaojiang fault is mostly a rock less desertification area.Lithology type plays a significant role in controlling the spatial distribution pattern of rocky desertification.Rock less desertification and potential rocky desertification are mostly distributed in non-carbonate areas , and rocky descrtification is mainly concentrated in carbonate areas and the rocky desertification phenomenon is serious in the pure limestone area, mostly in the intensity and moderate rocky desertification area.
