| 摘 要： | 文章利用2017年11月（秋季）和2018年4月（春季）对惠州考洲洋海域开展的两个航次水环境调查数据，分析了考洲洋海域表层溶解氧（DO）、化学需氧量(COD)、无机氮(DIN)、无机磷(DIP)和石油类（OIL）等典型水质因子的水平分布和季节变化情况。结果表明，秋季溶解氧、化学需氧量、石油类分别在盐洲岛以东附近海域、考洲洋湾顶海域和盐洲岛东南海域出现高值区，而无机氮在整个考洲洋无明显区域分布差异，无机磷含量呈现考洲洋内湾到湾口逐渐递减的趋势；春季化学需氧量、无机磷均在考洲洋湾顶出现高值区域，无机氮在盐洲岛以东附近海域出现高值区，而溶解氧和石油类无明显变化。从季节变化来看，秋季考洲洋海域溶解氧、化学需氧量和石油类平均含量均比春季高；无机氮、无机磷则相反，平均含量秋季低于春季。同时，文章还分别利用单因子和综合因子方法对海水有机污染状况进行评价并对其进行比较分析，结果表明，有机污染评价指数法可充分考虑多种水质因子，更适合对考洲洋水环境质量进行评价，得到较为客观的综合评价结果。

| Abstract: | The spatial and seasonal distribution patterns of water quality variables were analyzed,including dissolved oxygen(DO),chemical oxygen demand (COD),dissolved inorganic nitrogen (DIN),dissolved inorganic phosphorus(DIP) and petroleum (OIL) in the Kaozhou Bay in November 2017 (autumn) and April 2018 (spring).The results indicated that the contents of DO,COD,OIL displayed higher values near the east sea of Yanzhou islands,the top of the bay and the southeast sea of Yanzhou islands during the fall.Besides,there was no obvious difference in the content of DIN throughout the entire Kaozhou Bay,and the contents of DIP gradually decreased from the top to the bay mouth; In the spring,both the contents of COD and DIP displayed higher values in the top of Kaozhou bay,and DIN showed higher values near the east of Yanzhou island,while both the contents of DO and that of OIL showed no significant changes.In terms of seasonal change,the average contents of DO,COD and OIL in the autumn was higher than that in spring,while the average contents of DIN and DIP were lower in autumn than in spring.Additionally,this study also evaluated the status of water organic matter pollution by using the method of single factor and integrated factor,and the results showed that the organic water quality comprehensive index evaluational method including various factors were better for evaluating the water quality to obtain more objective comprehensive evaluation results. |
