摘    要:本文阐述了生物群落与生物环境的统一性,归纳了河流形态多样性的5种特征,指出了河流形态多样性是流域生物群落多样性的基础。水利工程可能引起河流形态的均一化及非连续化,从而降低生物群落多样性的水平,造成对河流生态系统的一种胁迫。水利工程建设应注意保护和恢复河流多样性,以满足生态系统健康的需求。

关 键 词:河流形态  生物群落  多样性

Abstract:The unity of bio-community and environment is expounded and the characteristics of river morphology are classified into five categories. It is pointed out that the diversity of river morphology is the basis of the diversity of bio-communities in a river basin. The existence of water projects may lead to the uniformity and discontinuity of river morphology, which may cause the reduction of diversity of river bio-communities and threaten the river eco-system. It is recommended that considerations should be given to the protection and rehabilitation of river morphology before the construction of water projects so as to meet the need of the establishment of a healthy eco-system.
Keywords:river morphology  bio-communities  diversity  water project  eco-system
