| 摘 要： | 岩溶水系统结构复杂,不同类型岩溶区具有不同的岩溶水文地质特征,其地下水系统防污性能评价必须采用不同指标体系的评价模型。本文在对不同类型岩溶区发育特征分析基础上,分别就现有评价模型在不同类型岩溶区的适应性进行了分析,认为:埋藏型岩溶区可采用专门用于承压含水层防污性能评价的PTHQET模型进行评价,而对于补给区局部裸露的浅埋藏性岩溶区建议采用COP模型进行评价;EPIK模型适用于南方裸露岩溶区;北方裸露型岩溶区因表层岩溶带发育程度弱,亦可采用COP模型进行评价。针对覆盖型岩溶的特殊性,在欧洲模型基础上提出了PLEIK评价模型,评价因子包括保护性盖层(P)、土地类型与利用程度(L)、表层岩溶带发育强度(E)、补给类型(I)和岩溶网络发育情况(K);突出了P(保护性盖层)和L(土地利用类型)两个因子的作用,并赋予各因子比欧洲模型更丰富的内涵,同时采用多种可替代参数确定各因子量值,最后给出了防污性能指数计算方法与分级标准。

| Abstract: | Due to the complicated structure of the karst groundwater system, different types of karst areas have different karst hydrological characteristics, and their vulnerability assessment models must adopt different evaluated indicators. Based on an analysis of the development characteristics of different types of karst areas, this paper discussed the applicability of the existing vulnerability assessment models to different types of karst areas. EPIK model can be applied to the bare karst area in South China, whereas COP model to the bare karst area in North China and shallow buried karst area with weak karst surface zone. PTHQE model can be specially applied to the buried karst area. On account of the particularity of covered karst, PLEIK indicators were put forward based on Europian Models. PLEIK model indicators include 5 factors, i.e., protective cover (P), land use (L), epikarst development (E), infiltration conditions (I), and karst network development (K). The model highlights two factors of P and L, and endows factors with more abundant intensions than Europian Models. In addition, several vicarious approaches for establishing the value of each factor are adopted, and the index calculation and classification assessment method are put forward. |
