Annual Change of Environmental Factors and Phytoplankton Community Characteristics in Maowei Sea of Qinzhou Bay
摘要
Abstract
Environmental factors,phytoplankton species composition, dominant species, amount of distribution and community structure were investigated in January,March,June and September of 2010 in Maowei Sea of Qinzhou Bay. The results showed that,in the survey area,the concentration of PO3r-P was 0.01 — 0.07 mg/dm3,DIN was 0. 16 — 0. 78 mg/dm3,and both values of PO^-P and DIN had scaled over Type IV water quality standards at some stations. 262 species belonged to 82 genera of phytoplankton were identified, and there were 16 kinds of dominant species among them. The phytoplankton abundance average was 6. 29 X 104 cells/L,and the annual average index of biodiversity was 3. 87. The species number of phytoplankton had a decreasing trend from winter to autumn. There was an obvious seasonal change in the cell a--bundance,being the lowest(3. 28X 104 cells/L) in spring(March) and highestO. 25X 10" cells/ L) in summer (June).关键词
