摘要
从3个方面对地下水开发利用与生态环境的关系进行了阐述:一是介绍了地下水开发利用现状及存在的主要问题。二是分析了不合理开发地下水对生态环境的影响,如地下水过量开采,形成了大范围的地下水降落漏斗;地下水位大幅度下降引起地面沉降;岩溶大泉流量不断减少甚至断流等。三是提出了合理开发利用地下水,保护和改善生态环境的对策。
From three aspects, this paper expounds the relationship between the development and utilization of the groundwater and the ecological environment： the first is to introduce the present situation of the development and utilization of the groundwater and main existing problems; the second is to analyze the influence of the irrational extraction of the groundwater on the ecological environment such as the large area＇s groundwater dropping funnel caused by the Overextraction, the land subsidence caused by the wide-range falling of the water height, and the continuous reduction and even interception, etc; the third is to put forward some countermeasures for making rational development and utilization of the groundwater and protecting and improving the ecological environment.
