摘　　要：以污染损失率模型作为理论模型,选取高锰酸盐指数、BOD5、NH3-N、挥发酚和石油类等污染因子对京杭大运河扬州段水体功能的受污染程度及其造成的使用功能价值损失进行了估计,得出了京杭大运河扬州段的年均污染损失率和综合污染损失率。基于实证分析结果,以综合污染损失率1%、20%、50%、80%作为分级标准点,对运河扬州段的水体功能污染损害程度进行了系统划分后,由综合污染损失率模型计算得出京杭大运河扬州段目前处于轻微损害级别,并提出扬州段相应的水污染治理方案及措施。The paper takes the Pollution Loss Ratio Model as the theoretical model,and selects the permanganate index、BOD5、NH3-N、volatile phenol and the petroleum as the study objects of pollution factors to estimate the water function's pollution degree and the consequent value loss of water function of Yangzhou section of the Grand canal,and calculates the average annual pollution loss rate and the comprehensive pollution loss rate.Based on the empirical analysis,the degree of the water pollution damage systematically by an integrated pollution loss rate of 1%,20%,50%,80%(which is the grading standards point) is classified,and draws a conclusion that Yangzhou section of the Grand canal is currently in a minor damage level.Then it put forward some measures to control its water pollution.
