摘  要：
依据2012年2月、5月、8月和11月三门湾17个站位表层沉积物质量调查结果,分析了沉积物总氮等污染物时空分布与污染特征及质量现状,结果表明:总氮等含量湾顶和湾口无明显差别,部分参数湾口含量略低;从季节变化看,粪大肠菌群含量2月最高,比其他月份大10倍甚至更多。细菌总数含量8月最高,比其他月份大10倍甚至更多。除总氮外,含量均能满足相应的标准。沉积物中有机碳平均含量比1987年升高了107%、比2002年升高了84.3%,与三门湾开发活动进一步加大有关。总氮和总磷平均含量比1987年分别下降了15%和8%、比2002年分别下降了42.0%和18.8%,总氮和总磷含量先升高、后降低,应该与氮、磷等污染物排放的控制有关。

摘  要：
The research was investigated in four seasons of 2012 including 17 sits of total nitrogen, total phosphorus, fecal coliform, total bacterial countin the surface sediments from the Sanmen bay. Moreover, the degree in spatial and space fluctuation of total nitrogen, total phosphorus, fecal coliform was analyzed. The re-sults showed total nitrogen is similar between the bay head and bay mouth, some even lower in the latter; the fecal coliform spatial fluctuation is highest in February, whose value is more ten times of the others. Similarly total bacterial count in August appeared. The area was not evidently polluted by our parameters except for light contaminated of total nitrogen with the local sediment quality standard. The average content of organic carbon this time is increased 107% of 1987's and 84.3% of 2002's, with the increase of Sanmen bay development intensity; On the contrary total nitrogen and total phosphorus value appears to be the lower 15% and 8% than1987's and 42.0% and 18.8% than 2002's, the fluctuation that hint the action of the government's policy.
