各级海洋环境质量公报均显示，我国近岸海域呈现以营养盐超标为主的污染特征。论文应用ArcGIS空间分析技术，充分利用已有环境监测数据，提取无机氮、活性磷酸盐空间数据，建立海域环境监测数据库，形成舟山近岸海域高分辨率的营养盐浓度空间分布图。研究结果显示：（1）利用已有资料形成的海域污染分布图与海洋环境质量公报中的描述基本一致，舟山海域营养盐污染呈现西南部相对严重的分布局势，本研究据较高的空间分辨率；（2）GIS空间分析手段，能够更加清晰的展示污染分布，提示各分区可能的污染源差异。该研究方法的进一步落实，能够实现环境监测数据的整合管理，有效提高现有监测数据的利用率，为污染源管理提供研究依据。

Marine environmental quality bulletins (MEQB), state or regional, all showed the eutrophication in China′s coastal area. In this study, spatial analysis was carried out using ArcGIS software to show the high-resolution distribution of inorganic nitrogen and reactive phosphate concentrations. The study was based on environmental monitoring data collecting. All the data collected was processed using ArcGIS 9.0 to build the database. The study showed(1) a relativeo colecting serious pollution in the west-southern part of Zhoushan sea area, similar to the nutrients distribution trends showed in MEQBs, but has a higher spatial resolution. (2) The study can show nutrients distribution in regional and sub-regional scale, and indicate a possible difference in pollution sources. With further study and application, our study may improve the sharing of monitoring data, in-crease the utilization of data, and provide basic research work for pollution source management.
