摘要
22个点位监测结果表明,大辽河口及辽东湾海域溶解氧与COD、无机氮、活性磷酸盐之间存在负相关关系；与初级生产力之间无明显的相关性；经过地理信息系统测算,该水域低氧区范围约为60～80平方公里.
In this paper, according to the results of 22 water quality monitoring spots, the positive correlation of DO to COD, inorganic nitrogen and reactive phosphate has been found. But the relation between DO and primary yield-power is not significant. Meanwhile, the area of low DO has been determined about 60 - 80km^2 .
