摘要
西部地区是我国地质灾害的重灾区。随着西部大开发战略的实施,该地区即将开展大规模的基础建设、能源开发等。区域内的经济发展与地质灾害的矛盾将不可避免地暴露出来。为解决这一问题,论文选取中国滑坡重灾区的江汉流域开展灾害危险性区划应用研究。研究区选在旬阳地区的县城近郊,通过MAPGIS软件平台及其二次开发的滑坡灾害分析系统,采用规则网格单元划分方法,运用信息量模型对该区斜坡稳定性进行了空间定量预测,并依信息量法的结果编制了该区的危险性预测分区图。为政府部门进行土地规划决策、避免在地质灾害易发区进行大规模土地开发和工程建设提供了科学依据。
The west area in China is the heavfy threatened zone by geo\|hazards,where will carry out the large\|scale basic construction,resource exploitation,etc with the West development,so the conflict between the economy development and the geohazard will emerge inevitably.In order to resolve the problem,the Han River valley in which the geo\|hazards are heavier is selected to develop the hazard zoning research.The study area is located in the suburb of Xunyang County.Based on the platform of MAPGIS software and further development,Information Analysis System of the Landslide Hazard,the paper applies the method of regular grid and the information value system to the spatial prediction about the area′s slope stability.Then the hazard zoning is compiled by the result of the information method,which will present the decision\|making about the land development and construction for the local government.
