摘要/Abstract

摘要： 本文应用PFU法对常德水系四季微型生物群落的结构和功能进行了分析。根据MacArthur-Wilson平衡模型提出了3个功能参数,测定了微型生物的2个结构参数。同步进行了16个站四季的水质分析,提出化学综合污染指数（P）。经统计学处理,P和微型生物群落的HI、S_eq、G、T_90%等指数均呈显著性相关。物种多样性（d）也在一定程度上反映出城市水体的不同污染程度。再次证明PFU微型生物监测方法的科学性,为生物监测提供了快速、经济、正确的新方法。

Abstract: In this paper, the structure and function of microbial communities in water system of Changde City were analysed asing PFUbio-monitoring method, and three functional parameters were put forward on the basis of MacArthur-Wilson's model. Besides, two structural parameters are determinated as well. Meanwhile, water quality of 16 stations for four seasons from 1986—1987 is analysed, and the chemical combined pollution index（p）is advanced. The results show that biotic parameters(HI, Seq, Gand T_90%) are closely correlated with the chemical combined pollution index（p）. The species diversity indices（d） could also reflect the pollution level to a certain extent. It is demonstrated that PFUbio-monitoring method is really a new rapid, accurate and economic way.

Key words: Microbial community, PFU, Bio-monitoring method, Structural parameter, Functional parameter
