从水文、水质、底质和生物生态等不同指标着手，筛选出9个二级指标和16个三级指标，建立了一套象山港海域生态分区指标体系．并利用 GIS 图层叠加技术对象山港海域进行空间异质性分析，将象山港从外湾至内湾划分为 A、B、C、D、E 5个区．其中，A 区和 B 区水交换能力较强，盐度较高，浮游生物以外洋种为主，底栖群落为粘土质粉砂-多毛类-织纹螺-蛇尾类群落，主要环境问题是水体重金属污染和沉积物石油类污染；C 区水交换能力较弱，水温较高，D 区和 E 区水交换能力差，盐度相对较低，水温相对较高．C 区和 D 区浮游生物以近岸温带种和暖海种为主，主要生态问题是水体重金属和石油类污染，有机污染和富营养化．E 区盐度低，浮游生物以半咸水种群为主，主要生态问题是有机污染、富营养化和重金属污染．

16 third hierarchy and 9 second hierarchy indicators are selected for the study from disciplines such as hydrology,water quality,sediment quality,bioecology and etc.A set of index system of eco-regionalization in Xiangshan Bay was established by the indexes.Based on GIS overlaid maps on the dimensional heterogeneity of Xiangshan Bay,the Bay can be regionalized into 5 areas.In area A and B,water exchange quickly and high salini-ty and offshore plankton species existed as a main feature.And the benthic community is presented by the clayey silty-polychaete-nassariidae-ophiurid.The environmental problems are heavy metal pollution in water and oil pollu-tion in the sediments.In area C,water exchange is weak and the water temperature is higher.In area D and E,the water exchange is poor with low salinity and relative high water temperature.In area C and D,temperate coastal species and warm sea species are dominant.The ecological problems are the water pollutions of heavy metals,oils, organic matters and eutrophication.The salinity in area E is low characterized by brackish plankton species.The main ecological problems of area E are organic pollution,eutrophication and heavy metal pollution.
