摘要
我国西藏地区海拔高度大,很多地方人车不能到达,传统水文地质调查方法往往难以满足工作需求。本文利用TM/ETM图像,在遥感图像数字处理的基础上,结合基于地学知识的图像识别和解译技术,对西藏那曲地区第四纪水文地质信息进行了提取,最后形成第四纪水文地质综合解译图,为那曲地区水文地质的进一步调查提供了科学依据,对高原地区水文地质调查具有很好的借鉴意义。
For the high altitude in Tibet, many areas can not reach only by automobile. So it is hard to satisfy our job needs just by traditional hydrogeological survey methods. Through processed remote sensing image of TM/ETM, this paper extract information related with hydrogeology of Quaternary Period which based on geoscience knowledge, finally formed hydrogeological remote sensing interpreted map synthetically. The research provided the scientific basis for farther hydrogeological investigation in Naqu,Tibet, At the same time, it is a reference for hydrogeological resource survey in the altiplano.
