本文对北京市水资源的现状进行了分析,阐明了北京市水资源紧缺的严重性,北京从1979年到1985年底已累计超采地下水36亿立米,郊区平原地下水位平均埋深已达9米以下,城区漏斗地下水埋深已降到40米以下。预测到2000年,若遇平水年,将缺水6.2亿立米;若遇枯水年则将缺水13.8亿立米。为解决北京市水资源紧缺问题,本文在综合了各有关方面的建议的基础上,提出了全面节流,适当开源,修建水源调配工程和加强水的管理体制的对策。文章还对充分利用雨洪问题作了比较详细的说明。
This paper analyzes the current situation of water resources in Beijing, clarifying the seriousness of water shortage in Beijing. Beijing has accumulated over 3.6 billion cubic meters of groundwater from 1979 to the end of 1985, and the average groundwater table in suburban areas has reached 9 meters The following, urban funnel groundwater depth has dropped to 40 meters below. It is predicted that by 2000, there will be 620 million cubic meters of water shortage in case of flat water years and 1.38 billion cubic meters of water shortage in the case of dry years. In order to solve the problem of water shortage in Beijing, on the basis of synthesizing the suggestion of all parties concerned, this paper puts forward the countermeasures of fully cutting expenditure, opening up source properly, building water source allocation project and strengthening water management system. The article also made full account of the problem of making full use of rain and flood.
