基于污染损失率的呼伦湖功能损害程度量化评价

Evaluation of Function Damage of Hulun Lake based on Pollution Loss Rate

以呼伦湖为研究区,根据2008年冰封期与非冰封期实测水质资料,运用水污染损失率为基础的评价方法,对呼伦湖湖泊使用功能损害程度进行评价,结果表明:无论是冰封期还是非冰封期呼伦湖水已不适宜作为饮用水源和游泳用水,作为渔业养殖用水、居住环境用水及农业灌溉用水其水质还是可以的,但旅游娱乐用水功能损害方面为中污染、中损害,并接近重污染、重损害水平,湖泊功能整体损害程度比较严重。

Based on economic loss rate of water due to pollution,the damage extent of utilizing function of water in the Hulun Lake was assessed through investigation,monitoring and analysis during the icebound season and non-icebound season in 2008.The results show that water in the Hulun Lake is not suitable for service as water source for drinking and swimming.As a sort of water used for fishing,irrigation and residential environment,it is still in good condition.But as a sort of water used for recreation,it is moderately damaged and close to seriously damaged.Its comprehensive damage extent is serious.
