摘要

针对广东岩溶地区覆盖型岩溶发育现状,结合区域水文地质条件,采用PLEIK模型对该区域地下水防污性能进行评价,对PLEIK模型的覆盖层(P)、土地开发利用(L)、表层岩溶发育程度(E)、补给类别(I)和岩溶网络发育强度(K)五大评价指标进行分区绘图和叠加计算,得出研究区的地下水防污性能评价图。结果可知:采用PLEIK模型对广东岩溶地区地下水防污性能评价取得了良好效果,从研究区地下水防污性能评价图上看出,防污性能较差的地区主要为岩溶发育的广大城镇区域,而防污性能好的地区一般为非岩溶区林地。研究结果对当地地下水资源合理开发利用和水污染防治提供了基础依据。
        According to the status of karst development in karst area of Guangdong Province, combined with regional hydrogeological conditions, the PLEIK model is used to evaluate the groundwater antifouling performance of the area. The cover layer(P), land development and utilization(L), surface karst of the PLEIK model. Development degree(E), recharge category(I) and karst network development intensity(K) The five evaluation indicators were divided into plots and superposition calculations to obtain the groundwater antifouling performance evaluation map of the study area. The results show that the PLEIK model has achieved good results in the evaluation of groundwater antifouling performance in karst areas of Guangdong. From the evaluation map of groundwater antifouling performance in the study area, it is seen that the areas with poor antifouling performance are mainly urban areas with karst development. Areas with good antifouling performance are generally non-karst area forest land. The research results provide a basis for the rational development and utilization of local groundwater resources and water pollution prevention.
