Abstract
A total of 30 genera of phytoplankton belonging to four divisions were identified. The highest of Shannon Wiener diversity index of phytoplankton were 2.463 in dry season of Trang River basin (TR4). The second-most abundant genera were Euglena and Pandorina. The water quality of all sampling sites were not clearly differed and classified as oligotrophic-mesotrophic status. Canonical correspondence analysis (CCA) after analyzed the relationship between the physico-chemical parameters and the phytoplankton. Among the environmental parameters, hardness and pH found to be the most important factors for Bacillaria and Gomphonema in the dry season. While, the wet season, Eudorina, Pleurosigma and Synedra were positively correlated with dissolved oxygen. Fragilaria was positively correlated with the ammonia content but Bacillaria was negatively correlated with total dissolved solids and conductivity.
