遥感图像在南水北调中线河北段选址中的应用

THE APPLICATION OF REMOTE SENSING IMAGE TO HEBEI SECTION OF MAIN WORKS OF DIVERTING SOUTH-WATER TO NORTH

拟议中的南水北调中线工程，南起长江三峡水库，横跨长江、淮河、黄河及海河流域，全长 １６００ｋｍ，是一项跨流域远距离调水，改变祖国面貌的宏伟工程。自５０年代起，该项工程就开始了 规划，并对其可行性进行了多方面科学论证和研究。１９８４年地矿部地质遥感中心沿黄河至北京段 进行了１：２万彩红外航空摄影，为河北段进行遥感解译试点工作提供了先决条件。本次工作选择 河北段长４７０ｋｍ，面积１８，９１６ｋｍ２进行遥感水文工程地质解译，取得了成功。

The main works of diverting south-water to north which the paper mentioned, from three gorges reservoir of Yangtze River, Cross Yangtze River, Huai River, Yellow River and their drainage area, is 1600 km long. That's great project which make great change to take place in our country.The programme of the project begin in 1950's, and its feasibility has been scientifically expounded and proved. In 1984, infrared colour aerial photography on the scale l/20000 had been finished along the main works from Yellow River to Beijing section by center of Remote Sense, Ministry of Geology and Mineral Resources in order to discuss the feasibility of the project and prepare to earlier work. In this time, we choise a section which is 407km long and 18916km2 in Hebei to have success- fully done the analysis of remote sensing on hydrological engineering geology.
