摘 要：为大力发展“保水渔业”，运用数学模型分析计算了水库水环境容量。根据水库水环境容量预测模型对水库的网箱养鱼污染负荷预测计算。计算结果：陆浑水库库区N、P的负荷均为9.08×10-4g/(m2.a)，LN 为2.75×10-2 g/(m2.a)，库区N、P的负荷均已超过库区水质富营养化N、P的危险界限LPD 1.94×10-3 g/(m2.a)、LN 2.90 ×10-3 g /(m2.a)值。从计算结果可以看出，该水库的总氮、磷由于受人为因素的影响，超出了水库水体的自净能力，库区已不适宜发展投饵网箱养鱼。

Abstract：Cage culture was developed into a fish feeding cage 1300m2 in Luhun reservoir from 1991 to 1994. The scale of farming up was to the peak for 45000 m2 in recent years, . Water environment capacity has been calculated by mathematical model of the reservoir of Luhun in order to develop vigorously “guarantees the water fishery”. lt is calculated for cage-culture of fish pollution load and quantity according to water environmental capacity forecast model . The result indicated that the loads of element N and P are 9.08×10-4 g/(m2.a) and 2.75 ×10-2g/(m2.a) respectively in the reservoir,.which have been more than N, P limits of the risk of LPD, LND 1.94×10-4g/(m2.a)and 2.90 ×10-3g/(m2.a )value of load reservoir eutrophication..The calculations show that the reservoir is not suitable for development throw the bait columned fish.because the total content of nitrogen, phosphorus in the reservoir is too high resulted in losing water self-purification capability due to the influence of the human element.

Key words: Cage-culture of fish; Feeding;carrying capacity; Luhun Reservoir
