摘    要:沿江开发是当今世界各国经济发展和国土整治关注的焦点,江苏省沿江开发过程中高密度和高强度的产业集聚将对长江江苏段水环境带来压力。根据江苏省沿江各地市社会经济和调查的环境监测资料,分析了沿江大开发背景下长江江苏段的水环境污染负荷及治理现状并预测了未来演变趋势,结果显示:2002年长江江苏段污染负荷的废水总量为210 997.80×10\+4 t,COD\-\{Cr\}总量为380 817.20 t,NH\-3 N总量为28 391.36 t;预测2010年将分别达到395 977.10×10\+4 t、598 197.80 t和42 381.56 t,较2002年分别增长87.7 %、57.1 %和49.3 %。污染源治理方面工业污水90%以上已达到了国家排放标准,而生活污水处理无论在污水处理厂数量还是处理深度都难以满足实际需要。为使长江水域生态环境不受破坏和饮用水源地的供水安全得到保障,提出了优化产业结构、削减污染负荷、加强生活污水处理厂建设和提高沿江主要支流的治理力度等多项调控措施。

关 键 词:长江江苏段  沿江大开发  水环境  污染负荷

Abstract:Nowadays almost all the countries are concerned of the exploitation and land harnessing along big river watershed. Industry clusters of high density and high intensity under the great exploitation in Jiangsu Province along the Yangtze River will bring pressure onto the water quality in the river. On the basis of the social, economical and investigated environmental monitoring data, the results revealed that the pollutant load of Yangtze River in Jiangsu province contains 210 997.80×10\+4t total waste water,380 817.20 t COD\-\{Cr\} and 28 391.36t of NH\-3 N in 2002,and will be 395 977.10×10\+4 t,598 197.80 t and 42 381.56 t respectively in 2010 as predic, with the increase ratio being 87.7 %,57.1 % and 49.3 % respectively. As for the polluted source treatment, more than 90% industrial waste water have met the discharge standard in China, but both domestic sewage disposal plant number and treatment depth can not meet the actual increase of domestic sewage treatment. On the purpose of the protection of ecological environment and the water source security, several principal countermeasures such as optimizing industrial structure, cutting down the pollutant load, strengthening the waste water treatment plant building and improving the main creeks treatment in the area are put forward.
Keywords:the Yangtze River in Jiangsu Province  great exploitation in Jiangsu Province along the Yangtze River  water environment  pollutant load
