福州市饮用水源浮游植物种群结构分析及比较

Analysis and Comparison of Phytoplankton Species Composition on Potable Waterheads in Fuzhou

从 2 0 0 1年 7月到 2 0 0 2年 6月 ,对福州市饮用水两大水源取水处 (山仔水库和闽江 )的浮游植物进行定性定量分析 ,还对不同取水处浮游植物的种类组成、数量和生物量的周年变化进行比较 ,并综合运用Margalef多样性指数对饮用水源的水质状况进行初步评价 .综合分析得出山仔水库水体营养水平相对较闽江的高 ,已达到富营养水平 ,闽江水也达到中营养水平 ,〗表明作为福州市饮用水的水源已存在不同程度的污染 .

Qualitive analysis and quantitalive analysis on the phytoplankton of the two potable waterheads which are Shanzai reservoir and Minjiang river in Fuzhou were carried out from July 2001 to June 2002.Phytoplankton species composition,quantity,biomass and change in different sampling stations were compared.Evaluation based on above and margelef diversity index suggested that the two waterheads have been pollutted and water quality of Minjiang river is better than that of Shanzai reservoir which belongs to eutrophicaion.
