摘　　要：宁夏山区水库存在大量点源污染、面源污染,以及内源污染,在研究宁夏山区茹河流域、清水河流域水库污染水体特征的基础上,根据水库协同治理、自然补水与人工循环相结合、污染控制与生态修复相结合等多种污水生态修复理念,研究了水库污染水体生态修复的可行性。考虑地域、水质条件,结合水库的污染程度、地质地貌特征和水库功能划分等,对宁夏山区水库污染水体进行生态修复。修复结果表明:修复前,污染水体水质基本不变,且局部污染物浓度上升;实施生态修复后,运行初期污染物浓度降低程度较大,修复结束后随着运行时间的延长,污染物浓度下降程度有所降低。The reservoirs in the mountainous area of Ningxia have a large number of point source pollution,non-point source pollution and internal source pollution.Based on the study on the characteristics of polluted water of reservoirs on the Ruhe and Qingshui rivers and according to the ecological restoration ideas of various pollution of cooperative control of reservoirs,the combination of natural water supply and artificial circulation and the combination of pollution control and ecological restoration,the paper studied the feasibility of ecological restoration of polluted water of reservoirs.Considering the regional and water quality conditions,the ecological restoration of the polluted water in reservoirs in Ningxia mountain area was realized by combining the pollution degree,geological and geomorphic characteristics and the function division of reservoirs.The results show that the quality of polluted water is basically unchanged and the local pollutant concentration has been increased before the restoration.After the implementation of ecological restoration,the pollutant concentration has been decreased significantly in the early stage of operation and decreases with the extension of operation time after the restoration.
