Abstract

chlorophyll a concentration is an important index of eutrophication. It becomes very necessary to timely and effectively monitor and evaluate the water chlorophyll a concentration for the environmental protection. Based on the satellite data from 2011 to 2016, the temporal and spatial distribution characteristics of the sea surface chlorophyll a concentration in the Beibu Gulf were analyzed. The results show that the chlorophyll a concentration in the Beibu Gulf has obvious monthly and seasonal variation, the monthly average chlorophyll a concentration reaches its peak in August and January, respectively, the average chlorophyll a concentration in the Beibu Gulf during winter and summer is higher than that during the spring and autumn, the chlorophyll a concentration in the Beibu Gulf sea surface begins to rise rapidly in summer, and the chlorophyll a concentration in the central and southern part of the Beibu Gulf slightly descend in autumn. In the spatial distribution, in the coastal waters of Beibu Gulf, the average chlorophyll a concentration is relatively higher, the high value area of chlorophyll a concentration is basically in the shallow water area along the western coast of the Leizhou Peninsula in the northern part of the Beibu Gulf, while the low value area lies in center and the deep waters of the south of the Gulf.
