| 摘 要： | 洱海湖滨区有鱼塘１４９．２５公顷，其有机物含量及换水量均与鱼产量成正比，每年向洱海排换水６７１．６万米＾３，输出Ｎ、Ｐ和ＣＰＤ分别为３３．２Ｔ、３．８３Ｔ、和４２０．４Ｔ。目前鱼塘正由混养型向精养型过渡，污染负荷亦将随之升级，必须及早研究，及早治理。

| Abstract: | There are 149 and a quarter hectares of pounds at the side of the Ehai Lake.The volume of the organic contents and the water changed increase in direct ratio to the growth of the fish output.Every year,6 716 million square meters of water is discharged into the Ehai Lake,in which N,P and COD are respectively 33 2 tons,3 83 tons and 420 4 tons.Since these pounds are being transformed from the mixed cultivation to the delicate mode and the pollutant loads will increase,research should be carried out as early as possible for the sake of prevention and treatment |
