重金属水污染经济损失计量模型与应用

Construction and Application of Estimation Model of Economic Loss f rom Heavy Metal Pollution

基于Hakanson生态危害指数评估理论和Costanza等建立的生态损失评估方法,建立了重金属水污染经济损失计算模型。利用该模型可定量地反映重金属水污染造成的经济损失。将该模型应用于深圳市4条主要河流1996~2003年的重金属污染损失计算,结果显示河流重金属污染造成的经济损失巨大。4条河流的年平均损失约为3.8亿元,其中深圳河最为严重,约为6.9亿元/a,4条河流的年平均经济损失依次为：深圳河〉龙岗河〉布吉河〉茅洲河。

On the basis of Hakanson＇s ecological harmfulness estimation theory and the ecological loss estimation method established by Costanza et al,an estimation model of economic loss from heavy metal pollution was constructed.This model can value the economic loss caused by heavy metal pollution quantitatively.The model was used to estimate the loss of heavy metal pollution of Shenzhen＇s four major rivers from1996 to 2003,and the result showed it would cause huge economic loss.The total average loss was 3.8 billion yuan per year of the four rivers.The loss of Shenzhen River was the most seriously,and it was about 6.9 billion yuan per year.The order of each river＇s average loss was Shenzhen RiverLonggang RiverBuji RiverMaozhou River.
