以CODMn、NH3-N、TN、TP作为污染指标，采用湖库均匀混合模型、狄龙模型和合田健模型对长湖纳污能力进行计算，并针对目前长湖水产养殖污染较重的特点，采用排污系数法、污染负荷率法对长湖水产养殖污染负荷进行估算。结果表明：长湖CODMn、NH3-N、TN、TP的纳污能力分别为8523.15 t／a、1495.57 t／a、1932.70 t／a、96.64 t／a，长湖水产养殖所产生的COD、NH3-N、TN、TP污染负荷量分别为3724.10 t／a、51.98 t／a、279.96 t／a、26.42 t／a。水产养殖对于长湖COD、TP的污染贡献较大是导致长湖有机污染和富营养化的一个重要污染源。

Choosing CODMn , NH3-N, TN and TP as the pollution indicators, we calculated the permissible pollution bearing capacity of Changhu Lake by using uniform mixture model, Dillion model and Hetianjian model. And in view of the current characteristics of the serious aquaculture pollution in Changhu Lake, we evaluated the aquaculture pollution load by the method of pollution discharge coefficient and pollution load ratio.The results indicated that the permissible pollution bearing capacity of CODMn , NH3-N, TN and TP were 8 523.15 t · a-1 , 1 495.57 t· a-1 ,1 932.70 t· a-1 and 96.64 t· a-1 , respectively;The aquaculture pollution load of COD, NH3-N, TN and TP were 3 724.10 t · a-1 , 279.96 t · a-1 , 26.42 t · a-1 and 51.98 t · a-1 , respectively.Aquaculture produce significant amount of COD and TP pollution to Changhu Lake and is an important pollution source of organic pollution and eutrophication.
