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。
Changes in Chla and Sea Surface Temperature (SST) occur when a green tide occurs, and Ocean Primary Production (OPP) also changes significantly. In this paper, we use the VGPM model to retrieve the spatial distribution of OPP in the Yellow Sea during the outbreak of green tide on July 15, 2009, and analyze the correlation between OPP, SST and Chla. The results showed that the OPP in the green tide area was higher than that in the non-green tide area, and the OPP in the green tide area was between 2600mgC · m -2 · d -1 and 3200mgC · m -2 · d ~ (- 1). The OOP of non - green tide was in the range of 1600 mgC · m -2 · d -1 and 1900 mgC · m -2 · d -1. At the same time, Chla in the green tide area is obviously higher than that in the non-green tide area, but the SST is lower than that in the non-green tide area.
