摘要
讨论了将信息量模型与 GIS系统结合 ,进行地质灾害危险性区划的方法。其基本思路是充分利用 GIS强大的空间图形和属性数据管理功能 ,实现对地质环境数据的分层次管理。在此基础上 ,利用信息量模型开发了基于 GIS的空间分析地质灾害危险性区划模块。最后 ,以长江三峡库区为典型实例 ,讨论了 GIS与信息量法模型结合及其在地质灾害危险性区划中的应用。
The assessment of geological hazards risk by combining information method model with geographical information system is discussed in this paper. The basic way of thought is that the layered management of the geological environmental data is realized by means of making the best use of the powerful spacial graph and property data management ability of GIS. Then, the spacial analysis module of GIS based information on assessment of geological hazards risk is developed. At last, GIS based information model is applied in the research area from Badong to Xintan in Three Gorge area of Changjiang River. The result shows that the combination of information method model with GIS is effective in assessment of geological hazards risk.
