摘  要：洪泽湖地处江苏省西北部淮河下游，是我国五大淡水湖之一，是江苏省淮安市、宿迁市、连云港市和徐州市的重要水源地。目前洪泽湖水体处于轻度富营养化状态，其原因之一就是周边地区工农业生产所产生的污染导致湖水中总氮浓度升高，湖水水质不仅远低于国家卫生部在1993年颁布的水源地水质标准并且逐步恶化下降为劣Ⅴ类。研究洪泽湖周边地区水污染的现状，对于洪泽湖水体污染的治理以及周边地区社会、经济、生态的协调一体化的发展具有重要意义。该文将从农业面源污染、工业污染、城镇生产与生活污染这三个方面去分析研究洪泽湖周边地区的水污染情况，并对洪泽湖水源地的保护提出多方面的建议。71502

One of the reasons is the pollution caused by industrial and agricultural production in the surrounding areas resulted in the increase of total nitrogen concentration. The water quality of the lake is not only far below when National ministry of health Water quality standards promulgated by the water source in 1993 and the gradual deterioration of fall into five class. To study the present situation of water pollution in the surrounding areas of Hongze lake is very important to control the Water pollution and development of social, economic and ecological integration of the surrounding areas. The article will study the water pollution situation by the widespread pollution from the overuse of fertilizers and pesticides in rural、the industrial pollution and the Urban production and living pollution and give some advice to protect the water head site of hongze lake.
