摘　　要：根据盐城自然保护区近海海域的监测数据,选取五大类代表指标,9个监测断面,运用SPSS统计软件对污染因子及主成分进行分析,研究主要污染因子的组合,并对相应污染源进行分析;通过聚类分析对近海海域的监测点及各监测点的污染数据进行分类,优化近海海域监测站点的分布,分析结果表明盐城自然保护区近海海域整体属于面源污染类型,但整个海域由北到南污染情况略有不同,海域北部偏重于化学污染类型,南部偏重于面源污染类型,分析的结论为该区域的环境监测及污染治理提供了重要的信息和依据。According to the monitoring data of Yancheng Nature Reserve coastal area, five representative indexes and nine monitoring cross sections were selected. Pollution factors and the principal components were analyzed by SPSS. The combining of main pollution factors were studied. The relative pollution sources were analyzed finally. Monitoring points of coastal area and the pollution data of each monitoring point were classified by cluster analysis. The distributions of monitoring points of coastal area were optimized. The conclusions were as follows ： the pollution of the whole Yancheng Nature Reserve coastal area is non - point source pollution. But the pollution situations are a little different from the north coastal area to the south coastal area. The pollution in north coastal area leans to chemical pollution. The pollution in south coastal area leans to non - point source pollution. The conclusions of the analysis provide important information and foundation for the environmental monitoring and pollution treatment.
