中线南水北调实施效益研究——初期引汉调水的必要性与可行性分析

华北地区缺水严重,根本解决途径在于南水北调.目前拟供水区地下水逐年下降,水源污染日益严重,供水紧张已成为制约工、农业生产的重要因素.本文通过对南水北调中线总干渠沿线的地质地貌、土质岩性,调水水源的水质状况,调水后的生态环境,以及实施后的经济效益等,进行了全面分析,结果表明,引汉调水不但必要,而且也是可行的.

STUDY OF APPLICATION EFFICIENCY OF TRANSFERRING WATER FROM SOUTH TO NORTH ALONG MIDDLE COURSE-AN ANLYSIS OF NECESSITY AND FEASIBILITY ON PRELIMINARY PROJECT OF TRANSFERRING THE HANJIANG RIVER WATER TO THE NORTH

The basic solution for water-deficient problem in the areas of northern China is to transfer water from south to north. The preliminary project of transferring the Hanjiang River water to north can satisfy the water needs of urban industries and daily life in the area, and of about 666,666 hactares of farmlands along the trunk-waterway of the middle course. At present time, yearly decreasing groudwater level, severe water pollution and water supply shortage become the main factors limiting the production of industry and agriculture in the water-deficient areas. This thesis gives an overall analysis on these areas geology, landform, soil texture and rock nature, on the water quality of transferred water source, and on the ecological environments and economic efficiency after water transfer. The results show that it is necessary and feasible to transfer the Hanjiang River water to the north.
