中文摘要：
采用FISH技术对2008年冬、夏两季太湖梅梁湾水体中细菌优势种群的丰度进行了对比分析．实验中，选取荧光素标记的特异寡核苷酸探针，与太湖梅粱湾水体中的四类细菌优势种群α-变形菌（α-proteobacteria），β-变形菌（β-proteobacteria），γ-变形菌（γ-proteobacteria）和拟杆菌（Bacteroidetes）进行原位杂交．结果表明：①所测定的四类细菌优势种群占总细菌的比例在冬季均显著高于夏季（P〈0．01）；②水体中α-proteobacteria的丰度随TP浓度的增加而显著增加（R^2=0．860，P〈0．01）；③随着Chl．a浓度的增加，水体中细菌的丰度呈上升的趋势，尤其是其中的y-proteobacteria，其增大趋势更加显著（R^2=0．857，P〈0．01）；④细菌种群的丰度受水体中PO4^3-浓度的影响，尤其是对Bacteroidetes的影响更加显著（R^2=0．733，P〈0．05）．
英文摘要：
FISH was used to analyze the abundance of dominated bacteria population in Meiliang Bay of Lake Taihu in winter and summer in 2008. The four dominated bacteria population （ α-proteobacteria, β-proteobacteria, T-proteobacteria, Bacteroidetes） were analyzed by in situ hybridization with specific fluorescently （FITC） labeled rRNA-targeted oligonucleotide probes in the test. The results indicated ： （1） The proportion of each of the four dominated species in the total number of bacteria was all significantly higher in winter than that in summer（ P 〈0. 01 ） ; （2） the abundance of α-proteobacteria rose notably with the increase of TP concentration （ R^2 = 0. 860, P 〈 0. 01 ） ; （3） there was ascending trend in the abundance of bacteria along with the increase of Chl. a concentration, especially that of γ-proteobacteria was more remarkable than the others （ R2 = 0. 857, P 〈 0. 01 ） ; （4） the abundance of bacteria population, especially for Bacteroidetes, was also influenced by PO4^3 - concentration （R^2 = 0. 733, P 〈 0. 05 ）.
