延吉市南部地下水特征浅析

A brief analysis of groundwater features in the southern of Yanji City

通过对地下水特征的分析认为:延吉市南部丘陵地带白垩系龙井组多旋回碎屑沉积岩风化孔隙、裂隙水,水质良好、水量中等、水质甘甜爽口、含有丰富的对人体有益的微量元素,具有良好的矿泉水开发前景。开发利用地下水资源时应采取:严格控制开采量、建立长期动态观测站、定期采取水样检测、设立卫生环境保护区等保护措施。

Through the analysis of the groundwater characteristics, the authors consider that multicycle clastic sedimentary rocks weathered pore water, ifssure water of Cretaceous Longjing Formation in southern hilly land of Yanji City have good quality, medium water yield, and have rich microelements that are beneifcial to human body. It has good development prospect of mineral water. We should take some protection measures in the development and utilization of groundwater resources, such as：strictly control the exploitation amount, establish long-term dynamic observation station, regularly take water sample to test, and establish health environmental protection area.
