吴忠市金积地下水饮用水源地保护区划分

对以地下水为主要供水水源的城市进行地下水饮用水源地保护区划分将提高饮用水的安全保障程度。在总结地下水水源地划分的原则和方法基础上,利用FEFLOW软件建立了吴忠市金积傍河型地下水水源地的地下水数值模型,模拟了规划的三种地下水开采情景下地下水的运动,并利用反向粒子跟踪技术和水源地划分原则和标准确定了三级保护区范围。该研究可为吴忠市和其他类似地区地下水资源管理和有效保护提供科学依据和参考。

Delineation of Drinking Groundwater Sources Protection Areas at Jinji County of Wuzhong City

Delineation of drinking groundwater sources protection areas at the cities where groundwater is main water supply sources will increase the degree to drinking water security. This paper summaried the delineation principles and methods of near-river drinking groundwater source proctection area, and established a numerical groundwater flow model using FEFLOW software. Three scenerios were simulated based on planned groundwater exploriation mode. Finnally three-level groundwater protection ranges were delineated using the method of inverse particle tracking. This study can provide scientific references for groundwater management and effective protection at Wuzhong city or other cities with silimar hydrogeological conditions.
