摘要
苏南大运河是江苏南部地区的大动脉,它对苏南地区的经济建设和人民生活具有举足轻重的作用。然而它的污染问题却十分严峻。治理污染首先必须了解污染状况。为此,本文从研究苏南大运河1984年至1987年的实测资料入手,分析了污染物具有量、时、空的三重属性,运用模糊数学的原理和方法,推导了污染物对水体功能相对破坏的经验可能分布的模式,并据此排列出苏南大运河10种超标污染物对运河危害大小的顺序,指明苏南大运河的污染主要属于有机污染型,进而阐明各种污染物质对运河污染的不同特征,以裨益于苏南大运河的环境管理和治理。
The Great Canal is the major water transport route, which plays an extremely important role in the economic development and people's living in southern Jiang-su, but is heavily polluted in recent years. The situation of its application must be investigated before its pollution can be controlled.Based on the water monitoring data of the Great Canal in Southern Jiangsu from 1984 to 1987, the pollutant' s three-dimentional characteristics in quantity, time and space are analysed. The principle of the fuzzy method is used to establish the experienced-possible distribution model in relative destruction at the function of water body. The harmful order of the selected ten pollutants in the Great Canal in southern Jiangsu is arr-abged. The results show that water pollution in the Great Canal in southern Ji an gsu is mainly caused by organic pollutants. The characteristics of various pollutants in the Canal are also clarified. The study would be benefit to the management of the Great Canal in southern Jiangsu.
