以岩溶地貌发育强烈的广西省来宾市吉利村为研究实例,首次借助于GIS缓冲区分析方法,通过对其塌陷程度的调查,结合研究区的地质状况,分析塌陷点分布位置与地质要素的关系。研究结果表明:塌陷点的分布位置主要与岩溶发育程度、地下河和断裂构造有关,与其他地质要素关系不大。这项研究为下一步岩溶塌陷成因的研究提供了参考数据,为当地经济发展布局和岩溶塌陷的防治工作提供了科学依据。
以巖溶地貌髮育彊烈的廣西省來賓市吉利村為研究實例,首次藉助于GIS緩遲區分析方法,通過對其塌陷程度的調查,結閤研究區的地質狀況,分析塌陷點分佈位置與地質要素的關繫。研究結果錶明:塌陷點的分佈位置主要與巖溶髮育程度、地下河和斷裂構造有關,與其他地質要素關繫不大。這項研究為下一步巖溶塌陷成因的研究提供瞭參攷數據,為噹地經濟髮展佈跼和巖溶塌陷的防治工作提供瞭科學依據。

In this paper ,Lai bin,Jili of Guangxi Province which develops strong karst landform is taken as an example to analysis the relations between the collapse point distribution and geological factors .It uses the GIS buffer analysis method which investigates the collapse degree , and combines with the geological condition of research area .The results show that: Collapse points ’ distribution is mainly affected by the degree of karst development , the underground river and the fracture structure , and it is very little to do with the other geological factors .The study provides reference for the study on formation cause of the karst collapse in the next step , and it also offers a scientific basis to the local economic development layout and Karst collapse prevention and control work .
