摘要(Abstract)：

针对不同模型对岩溶地下水脆弱性评价的适应性差的问题，以北方岩溶地区的典型代表济南趵突泉泉域为例，在分析岩溶区水文地质条件的基础上，结合地理信息系统技术，选取降雨入渗系数R、地形坡度T、岩溶网络K、土地利用类型L、上覆岩层厚度O和岩溶水流速V指标构建RTKLOV模型，用于评价岩溶水脆弱性，将评价结果与相关模型进行对比分析。结果表明：RTKLOV模型对岩溶水脆弱性评价适用性好，趵突泉泉城岩溶水脆弱性很低、低、中等、高、很高的面积占比分别为16.1%、 14.7%、 28.5%、 25.4%、 15.3%,与研究区实际情况相符；脆弱性指数I_d与水样中硝酸盐含量的Pearson相关系数为0.898,相关性好，评价结果准确、可信。
