摘要
地质灾害的频繁发生 ,给人类生命财产带来严重损失。因此 ,地质环境评价与地质灾害预测尤为重要。回顾国内外地理信息系统 ( GIS)技术在地质环境评价与地质灾害预测中的研究现状 ,讨论 GIS在地质环境领域应用中的可行性及技术路线。试图基于 GIS空间分析方法 ,结合地质环境评价模型 ,探索出一条地质环境评价 GIS系统的新途径。
Geological hazards such as landslides, rockfalls and debris flows happen frequently in southwestern China and bring about great damage to peoples′ life and property. Therefore, it is of great significance to develop an evaluation system of geological hazards based on the data from regional geoenvironmental investigations. In this paper, the up-to-dated status in this field is reviewed and a technical path and approach for this purpose based on GIS is discussed, and also a new approach to geoenvironmental evaluation based on GIS is researched.
