太湖渔业总产量与湖水化学耗氧量(COD)、太湖产量最高的刀鲚(Coiliaectenes)和虾类产量与湖水TN/TP、富营养化指数(TSI)与渔业总产量和刀鲚产量之间具有显著相关,并建立相应的回归方程;太湖富营养化加深与渔业总产量的增加,渔民人均收入的提高和经济发展是相一致的,湖泊富营养化程度增加对鱼类小型化具有促进作用。
The total output of Taihu Lake fishery and the chemical oxygen demand (COD) of lake water, the highest yield of Taihu Lake (Coiliae ctenes) and shrimp production and lake water TN / TP, eutrophication index (TSI) and total fishery output and knife production And the corresponding regression equation was established. The deepening of eutrophication in Taihu Lake and the increase of total fishery production, the improvement of fishermen per capita income and economic development are consistent, and the increase of lake eutrophication can promote the miniaturization of fish .
