基于GIS技术的水库库坝区岩溶发育特征分析

Karst development characteristics in reservoir and dam area based on GIS technology

以水库库坝区为研究对象,采用多层次高精度GIS解译方法,通过生成研究区DEM模型,分析地形数据,构建研究区GIS数据库和三维遥感影像解译系统,结合工程地质分析原理和灾害评价分析相结合的手段研究库区主要工程地质问题,对库坝区工程地质条件进行了解译。GIS、遥感等空间技术的应用对提高水库岩溶工程地质调查测绘等分析及研究工作的效率、工作质量有很大的理论和实践意义。

This paper takes a reservoir and dam area as the research object,adopte multilevel high-precision GIS interpretation method,generate the DEM model of the research area,analysis of terrain data,construction of GIS database and 3D remote sensing image interpretation system in the research area,the main engineering geological problems in the reservoir area are studied by means of combining engineering geological analysis principle and disaster assessment and analysis.To understand and interpret the engineering geological conditions of the reservoir dam area,the application of GIS,remote sensing and other space technologies has great theoretical and practical significance for improving the efficiency and quality of analysis and research work such as geological survey and mapping of reservoir karst engineering.
