Abstract:Based on the 4 cruises investigation data of phytoplankton in the Western Guangdong Waters from 1998 to 1999, we analyzed and simulated the spatial-temporal distribution patterns and the density center variations of phytoplankton cell abundance in the area with the linear interpolation method supported by Geographical Information System (GIS). Our results indicated that there was a distinctive spatial-temporal distribution of the phytoplankton in the Western Guangdong Waters. It had a similar distributio...
