摘要: 探讨了深圳市污染物排放总量对深圳东部海域赤潮发生的影响.结果表明:深圳市总氮(TN)、总磷(TP)净排放量以及排污中的N∶P与东部海域甲藻赤潮发生频率呈明显正相关;推算出东部甲藻赤潮爆发的TP、TN年排污阈值分别为3.917×103 t和2.123×104 t;而近岸排污与硅藻赤潮发生的相关性不明显.举例说明了深圳排污总量控制的具体方式.

Abstract: The study on the effects of pollutants discharge on red tide occurrence in eastern sea area of Shenzhen showed that the occurrence frequency of dinoflagellate red tide had significant positive correlations with the net discharge of total nitrogen (TN) and total phosphorous (TP) as well as the N/P ratio of the discharge. The thresholds of net discharged TN and TP were estimated to be 3.917×103 t and 2.123×104 t, respectively. No significant correlation was observed between diatom red tide and alongshore pollutants discharge. An example was given to illustrate the means of pollutants discharge control.
