中文摘要:
      随着现代经济的迅速发展,太湖流域污染问题日益严重.为了解太湖湖区以及入湖河流的水质变化趋势,分析两者之间的关系,本文选取太湖湖区以及环太湖22条主要入湖河流2007-2014年水质监测资料,按行政区划分析22条主要入湖河流的氨氮、高锰酸盐指数、总磷和总氮浓度变化趋势以及其与太湖水质关系.结果显示,江苏省境内河流2007年以来污染物浓度普遍高于浙江省,但主要入湖河流总体上呈好转趋势,并且河流各指标的浓度变化与太湖的水质变化密切相关,验证了河道污染物输入作为太湖主要的污染物外源,直接影响太湖水质的变化,指出对入湖河流污染物的控制是缓解和治理太湖污染输入的重要途径.
Abstract:
      Pollution is getting more serious in Taihu Basin with the rapid development of economy. In order to study the trend of water quality in Lake Taihu and the 22 major rivers into Lake Taihu, and their relationships. The total nitrogen, total phosphorus, ammonia nitrogen and permanganate index are analyzed using monitoring data from 2007 to 2014 by administrative divisions. Based on the analysis results, the rivers in Jiangsu Province are generally of higher pollutant concentration than the ones in Zhejiang Province since 2007. But the situation is improving in the 22 major rivers and the concentration changes of the rivers are closely related with the changes in Lake Taihu. It validates that pollutant transportation of rivers is the main pollutants of Lake Taihu and impacts on the changes in the water quality in Lake Taihu, and control of pollutants of the inflowing rivers is an important way to mitigation and treatment of pollution in Lake Taihu.
