河北省中东部区域分布为地下咸水分布区。自大量开采地下淡水以来,出现了地下咸水入侵地下淡水资源问题,第四系地下淡水水质呈不断变差趋势,对宝贵的地下淡水资源构成威胁,其主要原因是地下淡水资源的超量开采和成井工艺不严格。本文分析了地下咸水入侵地下淡水机制及影响现状。
The middle and eastern parts of Hebei Province are distributed as underground salt water distribution areas. Since the exploitation of underground fresh water in large quantities, underground freshwater intrusion by underground salt water has emerged. The freshwater quality of underground fresh water in the Quaternary has been deteriorating continuously, threatening the valuable underground freshwater resources. The main reason is the over-exploitation of underground freshwater resources And into the well process is not strict. This paper analyzes the underground freshwater mechanism of underground salt water intrusion and its impact on the status quo.
