摘要
地下水水源地保护区的划分是地下水资源合理开发利用的重要基础。为进一步完善地下水水源地保护区的划分方法,以大汶口盆地为例,在数值模拟法初步划分保护区范围的基础上,利用空间叠加分析,将地下水污染风险评价、防污性能评价与数值模拟法结合,调整保护区边界,并将基于数值模拟的空间叠加法与传统数值模拟法的区划结果进行了对比分析。结果表明:经空间叠加后的一级、二级保护区面积均向地下水补给源方向扩增,区划结果更贴合盆地实际。因此,将地下水污染风险评价和防污性能评价引入地下水保护区划分工作中,可以充分地利用研究区的水文地质信息和环境要素,提升高风险地区的保护级别,保障地下水可持续开发利用。
The delineation of groundwater source protection areas is an important basis for the rational development and utilization of groundwater resources.In order to further improve the division method of groundwater source protection areas, taking the Dawenkou basin as an example, based on the preliminary division of the scope of the protection zone by numerical simulation method, the spatial superposition analysis is used to incorporate the evaluation of groundwater pollution risk and anti-fouling performance with the numerical simulation method to adjust the boundary of the protection zone, and the results of spatial superposition method based on numerical simulation and traditional numerical simulation method are compared and analyzed.The results show that the area of primary and secondary protected areas after spatial superposition is amplified to the direction of groundwater recharge source, and the zoning results are more consistent with the actual situation of the basin.Therefore, the introduction of groundwater pollution risk assessment and anti-fouling performance assessment into the classification of groundwater protection areas can make full use of the hydro-geological information and environmental factors in the study area, improve the protection level of high-risk areas and ensure the sustainable development and utilization of groundwater.
