【摘要】：传统的Logistic模型在湖泊水污染经济损失计算上存在较大的偏差。通过对Logistic模型参数A、B值的修正,提高了TN、TP在模型计算中的所占比重。将修正前后的模型运用于邛海的水污染经济损失估算中,并将结果与邛海多年的水质综合污染指数的变化趋势进行比较。计算结果表明,修正后的Logistic模型计算的邛海水污染经济损失更符合邛海水污染多年的变化情况。修正后的Logistic模型可推广应用于其他湖泊的水污染经济损失计算中。
[Abstract]:The traditional Logistic model has a great deviation in the calculation of economic loss of lake water pollution. By modifying the parameters A and B of Logistic model, the proportion of TN,TP in model calculation is increased. The modified model is applied to the estimation of economic loss of water pollution in Qionghai Sea, and the results are compared with the changing trend of comprehensive pollution index of water quality in Qionghai for many years. The results show that the economic loss of Qionghai water pollution calculated by the modified Logistic model is more in line with the variation of Qionghai water pollution for many years. The modified Logistic model can be extended to the calculation of water pollution economic loss in other lakes.
