基于数值法的地下水饮用水源地生态红线划分研究OACSTPCD
Study of Stting up Ecological Protection Red Line of the Ground Water Sources of Drinking Water with Numerical Method
地下水生态红线是“生态保护红线”整体框架的重要组成部分,它保障地下水源水质,确保地下水源饮水安全.以四川省某地地下水饮用水源地生态红线划定为例,利用Visual MODFLOW建立研究区三维地下水非稳定流数学模型,进行地下水渗流场模拟,以水源地作为起点,确定地下水源开采处示踪粒子的逆向轨迹,反向计算在降解时间内水流到达水源地迹线的起点,以此获取地下水流截获区,水源地中心位置距红线最大距离为81.5m,最小距离为52m.为相关部门进行地下水水源地有效保护提供决策依据.
Groundwater ecological red line is an important part of the overall framework of the ecological protection of the red line,which guarantees the underground water quality,ensure the safety of groundwater for drinking water.In this paper ecological red line division of a groundwater source of drinking water in Sichuan province is used as an example established three-dimensional unsteady groundwater flow mathematical model of the study area by using Visual MODF…查看全部>>
