遥感技术在贵州矿山地质环境调查中的应用

贵州省是我国矿产资源大省之一，矿业是贵州省的支柱产业。矿业生产在促进全省经济社会发展的同时，也对矿山地质环境造成了较大的破坏。随着矿业开发的发展，矿山环境地质问题十分突出，严重影响矿区地质生态环境。本文论述了利用遥感技术开展矿山地质环境问题调查的方法与技术路线，对全省因矿山开采而诱发或产生的矿区生态环境恶化、水土流失、岩溶石漠化的加剧、水资源污染、地质灾害等各类矿山地质环境问题的遥感影像特征进行了总结。快速、准确、经济地摸清贵州省矿山地质环境现状及矿业开发对生态环境的影响；为合理开发矿产资源、保护地质环境、矿山环境整治、矿山生态恢复与重建、实施矿山地质环境监督等提供基础资料。

THE APPLICATION OF REMOTE SENSING TECHNIQUE TO THE INVESTIGATION OF THE MINE'S GEOLOGICAL ENVIRONMENT IN GUIZHOU PROVINCE

Mining is the pillar industry in Guizhou province.It was not only promoted economy's development and society's advancement,but also destroyed mine's geological environment hardly.The more mining exploitation increased,the more mine's geological environment serious,it affected on people's life living mining area.This paper discussed the method and technical flow which survey mine's geological environment by using remote sensing technique,and summarized the image's characteristics which is mine's geological environment,such as soil erosion,water pollution,geologic hazard,karst rock desertification,deterioration of the environment in mining area.This paper is based on multispectral remote sensing data(ETM+,SPOT5 and airborne remote sensing data),it is surveyed the mine's geological environment and influence which had brought out by mining for environment.It provided basic data for exploiting mineral resources,protecting geological environment,putting in order mine's environment,restoring and reconstructing mine's environment.
