摘要
系统在GIS具有的信息采集、分析和管理的强大功能基础上,建立空间信息数据库、评价指标信息库,采用权重法和模糊综合评判法,应用C++Builder和VC++7.0程序语言进行二次开发,对研究区地质灾害危险性进行预测和评价。
Guiyang is a karst mountainous city. Frequent geological hazards have a grave influence oft its economic development for last two decades. We should manage these geohazard information scientifically and recognize their distribution rules of investigation area fully. On the basis of GIS powerful function with information collection, analysis and management, the system builds spatial database and evaluation indexes information. Then, statistical weight method and fuzzy comprehensive judgment method are adopted to predict geohazard risk with C ＋ ＋ Builder and VC ＋ ＋ 7.0 program languages. The system not only provides scientific evidence for hazard damping and preventing, but also gives an important guidance on city construction, resource utilization and environment protection, etc.
