摘要和关键词

摘要: 岩溶水水位动态特征是开发利用和保护岩溶区地下水资源的重要依据,文章针对淮北市裂隙岩溶水水源地,结合地下水监测井数据、岩溶水赋存条件和水均衡法评价方法,对研究区裂隙岩溶水水位动态对大气降水的响应机制进行解析。结果表明:研究区的裂隙岩溶水受日降雨强度大于50 mm的次降雨影响最显著,且当基岩裸露区地下水埋深在25~35 m时,岩溶水水位对降水的滞后响应时间为6~9 d;受埋藏条件及上覆松散层厚度影响,研究区的地下水动态特征从北向南基本由降水入渗型演变为径流型。基于水均衡法预测评价得出,水源地周边水位抬升1 m时,西部水源地北段、西部水源地南段、东部水源地需分别增加储存量约 $ 765 \times 10^{4} $、 $ 890 \times 10^{4} $、 $ 450 \times 10^{4} $ m $ ^{3} $,该评价结果可为有序调控淮北市的岩溶水开采提供科学依据。

Abstract and Keywords

Abstract: The dynamic characteristics of karst water level are an important basis for the development, utilization and protection of groundwater resources in karst areas. Focusing on fissure karst water source in Huaibei City, based on the data from groundwater monitoring wells, karst water occurrence conditions and water balance evaluation method, this paper analyzes the response mechanism of fissure karst water level dynamics to precipitation in the study area. The results show that the fissure karst water in the study area is most significantly affected by rainfall with a daily intensity greater than 50 mm. Moreover, when the depth of karst water in the exposed area is 25-35 m, the response time of karst water level to precipitation is 6-9 d. Affected by the burial conditions and the thickness of the overlying loose layer, the groundwater dynamic characteristics in the study area basically change from the precipitation infiltration type to the runoff type from north to south. Based on the prediction and evaluation of water balance method, when the water level rises about 1 m, the storage capacities of the northern section of the western water source, the southern section of the western water source and the eastern water source need to be increased by about $ 765 \times 10^{4} $, $ 890 \times 10^{4} $, $ 450 \times 10^{4} $ m $ ^{3} $, respectively. The evaluation results can provide a scientific basis for the orderly regulation of karst water exploitation in Huaibei City.

Keywords: fissure karst water; dynamic characteristics; precipitation; water balance method; response mechanism
