摘要
以淮北市裂隙岩溶水源地开采实际为研究对象,利用水位自回归与多元回归相耦合的方法建立水位动态模拟模型;根据对1997-2004年期间实际水位动态的模拟过程与结果,论述耦合方法计算精度较好的内在原因,阐述该方法的优越性;结合区域水位动态特征,分析区域裂隙岩溶水超采的成因,从用水公平角度讨论超采临界水位的确定方法,利用动态模拟模型评价水源地的超采程度;基于区域水位动态特征和超采评价结果,探讨水源地限采的技术思路。
Based on the study of actual exploitation of fracture-karst water in Huaibei City, the water level dynamic simulation model is built up by using the coupling method of water level autoregression and multivariate regression. According to the dynamic simulation process and results of the actual levels in the period from 1997 to 2004, the coupling method can produce high calculation accuracy, and the advantages of the method are described. Based on the dynamic feature of the regional water levels, the causes of excessive extraction of fissure-karst water are analyzed. The determination method of a limiting water table is discussed from the perspective of fair water, and the dynamic simulation model is used to evaluate the extent of excessive extraction of water. Based on the dynamic features of regional water levels and the overdraft evaluation results, the technical scheme for pumping limitation in the study area is discussed.
