【摘要】:华北平原地下水严重超采,并带来一系列资源环境问题,地下水资源承载力的可持续性面临严重挑战。本研究定义了地下水资源承载力的概念,提出了一种定量评价地下水承载力的新方法,并对华北平原地下水承载力进行了评价。结果表明,华北平原地区地下水资源支撑的GDP从2003年的15 608.18亿元迅速提高到2011年的37 584.9亿元,33.3%的地市位于未超采未超载区;华北平原整体及57.2%的地市均位于超采未超载区,已发生地下水超采,但通过提高用水效率,未来社会经济规模仍有发展空间;9.5%的地市位于超采超载区。最后探讨地下水资源的承载力的提高途径,主要包括增加地下水资源可利用量和提高用水效率两方面,其中提高用水效率效果更显著。
[Abstract]:Groundwater in North China Plain is seriously overexploited and brings about a series of problems of resources and environment. The sustainability of groundwater resources carrying capacity is facing serious challenge. In this paper, the concept of groundwater bearing capacity is defined, and a new method for quantitative evaluation of groundwater bearing capacity is put forward, and the groundwater bearing capacity of North China Plain is evaluated. The results show that the GDP of groundwater resources in North China Plain rapidly increased from 1.560818 trillion yuan in 2003 to 3.75849 trillion yuan or 33.3% in 2011, and the whole North China Plain and 57.2% of the cities are located in unoverloaded areas. Groundwater has been overexploited, but by improving the efficiency of water use, 9.5% of the cities will still be located in the overloaded areas in the future. Finally, the paper discusses the ways to improve the carrying capacity of groundwater resources, mainly including increasing the available quantity of groundwater resources and improving the efficiency of water use, among which the effect of improving the efficiency of water use is more obvious.
