摘　　要：绿潮发生时叶绿素浓度(Chla)和海水温度(Sea Surface Temperature,SST)会发生变化,此时海洋初级生产力(Ocean Primary Production,OPP)也会出现显著变化。本文利用VGPM模型反演了2009年7月15日绿潮暴发时黄海OPP得到其空间分布情况,并且着重分析了OPP与SST、Chla之间的相关关系。研究发现绿潮区域的OPP高于非绿潮区域,其中绿潮区域的OPP在2600mgC·m^(-2)·d^(-1)至3200mgC·m^(-2)·d^(-1)之间,非绿潮的OOP在1600mgC·m^(-2)·d^(-1)至1900mgC·m^(-2)·d^(-1)范围内。同时绿潮区域的Chla明显高于非绿潮区域的Chla,但SST比非绿潮区域低一些。Chlorophyll a and sea surface temperature will change when green tide breaks out,and ocean primary productionwillalso change quickly. In this study, we obtained yellow sea green tide＇s OPP space distributionon July 15, 2009using VGPM modeland emphatically analyzedthe correlation between OOP with chlorophyll aand sea surface temperature. The result showed that the OOP of green tide area was higher than that of normal regions, and the green tide ocean primary production numerical value ranged between 2,600mgC m^-2·d^-1 and 3,200mgC ·m^-2·d^-1 while that of normal regionsvaried between 1, 600mgC·m^-2·d^-1 and 1,900mgC·m^-2·d^-1. Meanwhile the chlorophyll a ingreen tide areawas obviously higher than that of normal regions, but sea surface temperaturewasslightly lower than that of normal regions.
