| 摘 要： | 根据2009年8月和10月夏、秋季节中街山养殖区调查数据,对该海域的营养盐水平及有机污染现状进行了分析评价。结果表明：中街山列岛养殖区无机氮夏季含量较高,16.7%的站位超四类水质标准,秋季明显下降,符合二类水质标准。活性磷酸盐含量夏、秋季无明显差异,而硅酸盐秋季较夏季明显升高。磷酸盐为该海域的限制因素,夏季尤为明显。该海域已呈富营养化状态,有机污染也已达到轻度污染水平,且夏季高于秋季。

| Abstract: | The nutrient level and organic pollution was evaluated in Zhongjieshan archipelago sea areas,according to the investigation result in summer and autumn.The result showed that the concentration of inorganic nitrogen was higher in summer,about 16.7% of the areas exceeded the fourth grade of sea water quality standard.The concentration of inorganic nitrogen decreased obviously in autumn,according with the second grade of sea water quality standard.The concentration of inorganic phosphate in the seawater had no... |
