摘　　要：为探究渣土场渗排水对水库的环境风险,以广东省深圳市某水库及上游渣土场为研究区,对水文地质条件进行合理概化,采用FEFLOW软件进行了地下水水流模拟研究。结果表明,模拟得到稳定流和非稳定流状态下地下水水流动态变化趋势,显示渣土场的渗排水对水库水位和水质具有一定的潜在影响。在有稳定的降水补给条件下,地下水水位主要受控于地形,上游渣土场地下水流动特征呈自北向南流动,对水库形成环境风险。渣土场地下水与水库地表水的交互关系表现为地下水对库区水质影响较弱,地表径流是威胁水库水质的主控因素,采取地表径流控制措施对污染控制最为有效。研究结果可为保障水库水质及供水安全提供参考。In order to study the environmental impact of the seepage and drainage from the municipal solid waste landfill on a reservoir,the reservoir and upstream municipal solid waste landfill in Shenzhen,Guangdong Province were selected as the research area,and the study of groundwater flow simulation was conducted by combining FEFLOW software based on the generalized hydrogeological conditions of the research area.The results indicated that the dynamic changes in groundwater flow under stable and unstable flow conditions were simulated,indicating that the seepage and drainage of the municipal solid waste landfill have a certain potential impact on the water level and water quality of the reservoir.The groundwater flow characteristics of upstream municipal solid waste landfill flow were from north to south bring environmental risk to the reservoir,resulting from the groundwater level controlled by the terrain under stable conditions of precipitation replenishment.The interactive relationship between the groundwater under the municipal solid waste landfill and the surface water of the reservoir showed that the water quality of the reservoir area was mainly threatened by the surface runoff,but not by the groundwater,and surface runoff control measures taken will be most effective on pollution control.The research results provides a reference for ensuring the water quality and water supply safety of reservoirs.
