摘要:
【摘 要】文章研究自然过程与人类活动等因素对岩溶水化学的影响，探讨污染水体的渗流场问题，对实施鹤庆岩溶水资源的开发和污染防治具有重要的意义。以鹤庆岩溶水28个水点为研究对象，通过统计分析、Piper三线图、主成分分析和AHP-层次分析，研究了鹤庆岩溶水的水化学特征，并分析鹤庆岩溶水污染水体渗流场问题。研究结果表明：鹤庆岩溶水系统中的K+、Na+、TFe（水中总铁含量）、Cl-、SO42- 和 NO3- 的空间变异性较大，属于强度变异；水化学类型整体上为HCO3—Ca·Mg 型，表明水化学形成作用主要因素为典型的碳酸盐岩地区的溶滤作用。主成分分析结果表明鹤庆岩溶水的水化学特征受水岩作用和人类活动的叠加影响，其中自然属性受水岩作用（矿物或岩石的溶解）的控制而煤矿开采和农业生产等人类活动是造成岩溶水地球化学特征差异性的主要影响因子；基于AHP-层次分析方法的污染水体渗流场综合评价结果表明：KW-14 与受污染样点KW-28 存在水力联系最大，综合评价值为72.464；同示踪实测结果一致，证实污染水体渗流场综合评价的准确性和可靠性。
Abstract:
seepage field of polluted water, which is of great significance for the development of Heqing karst water resources and preventionand control of pollution. This paper chose 28 water points, studied the hydrochemical characteristics of Heqing karst water system andanalyzed the seepage field of polluted water body through the methods of statistical analysis, piper trilinear nomograph, principalcomponent analysis and analytic hierarchy process. The results showed that the spatial variability of K+, Na+, TFe（the total Fe amount ofwater）, Cl-, SO42- and NO3- is large, which belongs to the intensity variation. The hydrochemistry type is HCO3-Ca·Mg as a whole,which shows that the hydrochemical formation is mainly the lixivation in typical carbonate area. The results through principal componentanalysis showed that the hydrochemical characteristics of Heqing karst water system are affected by water-rock interaction and humanactivities. The natural properties are controlled by water-rock interaction (the dissolution mineral or rock ) and human activities such ascoal mining and agricultural production are the main factors that cause the difference of geochemical characteristics of karst water. Thecomprehensive evaluation of the seepage field of polluted water based on analytic hierarchy process showed that the hydraulicconnection between KW-14 and the contaminated sample point KW-28 is the largest, with a comprehensive evaluation value of72.464.Consistent with the tracer experiments results, the accuracy and reliability of the comprehensive evaluation on the seepage field inpolluted water were confirmed.
