厦门市坂头水库和汀溪水库水中浮游藻类种群组成特征研究

2009年-2010年采集汀溪水库和坂头水库水样,制片,电子显微镜下观察,研究结果表明:汀溪水库藻类共有4门,其中,蓝藻门最多,其中的拟浮丝藻数量高达5.4×107个/L,其次是绿藻门,再次是硅藻门,甲藻门最少。坂头水库藻类共有4门,其中,硅藻门最多,其中的颗粒直链藻数量达到1.01×107个/L;绿藻门、甲藻门和蓝藻都非常少。根据指示藻类标准初步鉴定坂头水库和汀溪水库属于中-富营养化型(β-α-ms)水体。同时分析和讨论了藻类引起的潜在水质问题。

Investigation on Characteristics of Algae Population in Bantou Reservoir and Tingxi Reservoir

Water sample from Bantou reservoir and Tingxi reservoir during 2009 -2010 were collected and observed by elec- tron microscope. The investigation results indicated that there are four phylum in Tingxi reservoir. The largest communities were bacillariophy and planktothricoides was 5.4×107/L. The next largest community was chlorophyta. Bacillariophy was less and pyrrophyta was the least. There were 4 phylum in Bantou reservoir. The largest community was cyanophyta, and melosira granu- late was 1.01×10T/L, chlorophyta, pyrrophyta and cyanophyta were less. According to the identification standard of algae indi- cator, Tingxi reservoir and Bantou reservoir were meso - eutrophic. The potential causes for quality change by algae was analyzed and discussed.
