万家寨引黄工程太原供水区地下水合理利用与调控研究

Study on Rational Development,Regulation and Control Of Groundwater in Taiyuan Water-supply Area of the YRDP

引黄工程南干线通水后，合理分配调度各种水源，使长期处于超采状态的太原供水区地下水“休养生息”，从而达到供水区社会经济可持续发展、资源可持续利用的目标。

In this paper,the following contents are included.The basic condition of Taiyuan water-supply area of the YRDP.The total area of the water-supply area is 3,000 km 2,having about 2,300,000 of population.The groundwater is used as a main water source.The serious overdraft has occurred since 1980's.The mining coefficient (actual mining amount over permissible mining amount) K value is 1.257,the highest value is as high as 1.748 in a hydrogeologic unit(1984-1996).The rate of groundwater drawdown reaches 3.50 meters a year (1981-1996).The regulation or control scheme.The total water-supply area are divided into 10 subareas on the basis of taking account of the integrity of hydroleologic unit,the regulation or control scheme is contrived with respect to each the subarea.There are,four guiding principles:the scheme is favorable to sustainable use of the water resources,to sustainable development social and economical in the water-supply area and so on,and 3 stages of the regulation or control:1997-2001,2002-2009,and 2010-2015.The water that is diverted from the Yellow River by the YRDP is expected to be sent to Taiyuan water-supply area in the year 2002.The final aim that the water supply balances the water disposal,including the mining of the regulation or control scheme will be realized after the year 2010 gradually.Mathematical simulation was done for the groundwater regime of eleven of the regulation schemes in the third stage(2010-2015).The recommended schemes in this paper have been obtained after appraising the regulation effect about each above scheme.This study was finished in June,1998.
