摘　　要：按《地表水和污水监测技术规范》对长湖水环境质量进行采样、监测和分析,并利用GIS技术对长湖水体主要污染物的空间分布现状进行探讨.结果表明,3种主要污染物CODcr、TN、TP都达不到规定的Ⅲ类水质标准,超标率分别为92.3%、100%和53.8%.基于CODcr、TN、TP 3种主要污染物的空间分布图形叠加后,长湖大部分水域水质为Ⅴ类和劣Ⅴ类,只是在主要出水口习家口和刘岺闸附近的小部分水域可达到Ⅳ类水质.该研究对了解长湖水质现状和制定长湖水污染防治规划有重要意义.This article has carried on the sampling, the monitoring and the analyzing to the Changhu Lake water quality according to the ＂Technical Specifications Requirements for Monitoring of Surface Water and Waste Water＂ （H J/T91-2002）, and probed into the present spatial distribution of main pollutants by using the GIS technology. Results indicated that, three main pollutants of CODcr, TN, TP were larger than the values of Ⅲ, exceeding ratewere 92. 3%, 100%and 53.8%respectively. Based on the superimposition of spatial distribution graphs of CODcr, TN, the TP, the majority water quality of Changhu Lake reached Ⅴ or exceeded Ⅴ, only in the main outlet Xijiakou and Liuling floodgate can achieve Ⅳ. This research have important significance to study on the present water quality of Chang Lake and formulate the Changhu Lake water pollution preventing and controlling plan.
