| Abstract: | Based on the biomass, diversity index and evenness obtained from theecological investigation in the Daya Bay waters from Oct. 1990 to Oct.1991, thespecies, dominant species, seasonal substitution,biomass change, and spatial andtemporal distribution of phytoplankton in the Daya Bay are analyzed statistically bythe methods of factor analysis and principal component analysis etc. The results showthat the phytoplankton in the Daya Bay has the characters of subtropical organisms: (1)The warm species and wide-distributed species are major components and the formeris more than the latter. (2) The dominant species change frequently and their numbersand biomasses change also. (3) The diversity index and evenness of phytoplankton arecommonly high except in spring. (4) The seasonal change of biomass has only a peak.(5) The Daya Bay warers can be divided into two parts, stations 1-3 belong to oneand stations 4-9 the other. Compared with the latter out of the Dapeng Bay, theformer, located in the Dapeng waters, has a high biomass, clear dominant species andlow evenness and diversity indexes. |
