摘　　要：大庆有着丰富的湿地资源,生态经济价值极大。近年来,随着大庆经济的快速发展,湿地污染情况严重。选择具有代表性的龙凤湿地进行研究,通过对湿地上覆水体及底泥间隙水各项指标的测试,分析了龙凤湿地污染情况。结果表明,该湿地水体及底泥均受到严重污染,底泥间隙水中污染物含量约为上覆水体3倍左右。表层底泥中污染物含量最高,其总氮(TN)、总磷(TP)含量在垂向上呈下降趋势。针对龙凤湿地的水污染情况,必须同时采取内外源的治理措施,在有效截污的情况下,有必要对底泥进行疏浚,同时将多种修复手段进行联用,但仍需要更深入和精确的研究来确定底泥疏浚深度。The wetland resource of Daqing is abundant, its ecological and economic value is enormous. In recent years, with the rapid development of Daqing economy, wetland pollution is becoming very serious. In this study, the pollution of Longfeng wetland was analyzed by testing the indexes of the upper water and the pore-water of sediments. The results showed that the pollution of the wetland water was serious, the pollutant content in the sediment pore-water was about 2~3 times as that in the upper water;the nitrogen, phosphorus and other organic pollutants in the pore-water of the sediment was likely released into the above water due to the concentration gradient. The organic pollution of surface sediment was the most serious. The contents of total nitrogen（TN）, total phosphorous（TP） in sediment were both decreasing in vertical direction. In view of the water pollution situation in Longfeng wetland, it is necessary to take both internal and external treatment measures. In the case of effective pollution interception, it is necessary to dredge the sediment and combine various restoration methods. However, more in-depth and accurate research is needed to determine the depth of sediment dredging.
