根据2008~2011年调查资料,分析椒江口及邻近海域夏季类时空分布特征,并采用单因子指数法对其进行评价.结果表明,椒江口及邻近海域夏季水体中油类含量为0.010~0.178 mg?L-1,平均0.038 mg?L-1.空间分布上具有明显的河口区特点,由近岸向外海递减;油类含量年际变化范围为0.032~0.046 mg?L-1,总体上呈现先升后降趋势.海域各测站沉积物中的油类含量均符合一类沉积物质量标准,其空间分布并无规律,与水体中油类含量也无显著关系;海域油类含量与环境因子之间呈线性相关,按相关系数大小排列依次为:盐度>pH>活性磷酸盐>无机氮>COD;不同年份间的相关程度也不相同,各年份相比较,2009年油类含量总体较高,但线性相关较差.

From 2008 to 2011, Jiaojiang Estuary and adjacent coastal waters were investigated in a move to analyze the spatial and temporal distribution characteristics and to evaluate the pollution condition using single factor index. In this study, the concentrations of the summer oil is found to range from 0.010 to 0.178 mg?L-1 (mean concentration, 0.038 mg?L-1). Oil concentrations are decreased from coast to offshore area, indicating obvious specificity of estuary distribution. For temporal distribution, on the other hand, the interannual variation ranges from 0.032 to 0.046 mg?L-1, which generally rises first followed by decreasing. The oil concentrations and environmental factors takes on a linear correlation and the order on coefficients of which is salinity > pH >reactive phosphate > inorganic nitrogen > COD. The coefficients of correlation differ according to areas and years, and this observation is especially true in Jiaojiang estuarial region.
