摘　　要：划分准保护区是水源地污染防治的重要依据与措施,前人通过河流附近抽水井准保护区理论研究将其分成三类。此次基于泰莱盆地多水系多水源地特征,利用数值法获得地下水流场,并用MODPATH划分水源地准保护区。根据计算结果对泰莱盆地内水源地准保护区进行划分,分析准保护区面积与开采量、开采深度、水源地到河流距离之间的关系;为前人理论研究提供了实际支撑,并将傍河水源地准保护区增加到五类;通过水源地附近流线分析得出开采水的来源区域并进行归类,分析了准保护区类型随开采量变化的特征;利用准保护区与河流间位置关系得出附近河水及河流另一侧地下水对水源地水质的影响,进而为水源地监测规划提供科学依据。The classification of quasi-protected areas is an important basis and measure for water source pollution prevention and control.The former researchers divided the quasi-protected areas into three types through theoretical research on pumping wells near rivers.Based on the characteristics of multiple water systems and water sources in Tailai Basin,the groundwater flow field was obtained by numerical method,and the quasi-protection area of water sources was divided by MODPATH.According to the calculation results,the quasiprotection zone of water source area in Tailai Basin was divided into three parts,and the relationship between the area of quasi-protection zone and the amount of exploitation,the depth of exploitation,and the distance between water source area and river was analyzed.It provided practical support for previous theoretical research,and increased the quasi-protection area of riverside headland to five categories.By analyzing the flow line near the water source area,the source area of mined water was obtained and classified,and the characteristics of the types of quasi-protected areas with the change of mining amount were analyzed.Based on the position relationship between the quasiprotected area and the river,the influence of the nearby river and the groundwater on the other side of the river on the water quality of the water source area was obtained,which provided a scientific basis for the monitoring and planning of the water source area.
