基于GIS对岩溶塌陷预测及评价的方法

THE SUBSTITUTION OF THE CARST FORECASTING AND EVALUATING METHODS BASED ON THE GIS

根据GIS强大的数据综合处理功能及其在地质灾害预测与评价方面的应用,通过对岩溶塌陷的区域条件、影响因子、预测及评价过程的研究,建立了以GIS、RS、GPS组成的空间信息技术体系应用于对象的技术手段确定评价指标和体系,收集评价数据,结合评价信息的处理和提取,实施评价模型,划分岩溶塌陷度综合等级。此方法的思路与方法似值得借鉴。

The paper studies the regional conditions, factors and Prediction and evaluation process of carst collapse,combined with the powerful data processing ability of GIS and its application in prediction and evaluation of geological disasters. Then the new methods and ideas based on GIS are established,the direction for prediction and evaluation of carst collapse has been indicated.
