地下水过量开采,地下水位持续下降,是形成地下水降落漏斗的主要原因。截止2014年底,新乡市共有地下水漏斗区5处,总面积约12.53万hm~2,漏斗中心地下水埋深约为10~18 m左右,且呈现范围逐年扩大、埋深逐年加深的趋势。文章在对各漏斗区的形成与发展详细介绍的基础上,对漏斗区补源的可行性进行了初步分析,并提出解决漏斗区相关措施,为新乡市解决地下水漏斗区问题提供了技术支撑。
Groundwater over-exploitation, groundwater level continued to decline, is the formation of groundwater descent funnel the main reason. By the end of 2014, Xinxiang City has 5 groundwater funnel areas with a total area of about 125,300 hm 2. The groundwater depth at the center of the funnel is about 10 to 18 m, and the scope of the groundwater system has been expanding year by year. Based on the detailed introduction of the formation and development of each funnel zone, the article makes a preliminary analysis of the feasibility of supplementation of the funnel zone, and puts forward some measures to solve the funnel zone and provides technical support for solving the problem of groundwater funnel zone in Xinxiang City.
