保护和恢复河流形态多样性

Protecting and Rehabilitating River Form Diversity

生物群落与生态环境的统一性是生态系统的基本特征。河流形态多样性是流域生态系统生态环境的核心,是生物群落多样性的基础。水利工程在不同程度上造成河流形态的重大改变,导致生物群落多样性的降低,影响河流生态系统的健康和稳定,从而使系统的服务功能下降,对人类利益造成损害。水利工程建设应该重视保护和恢复河流形态多样性问题,转变工程理念,在满足人的需求的同时,兼顾流域生态系统健康的需求。

Consistency of biotic community and eco logicaI environment is a basic element of ecosystem. Diversity of river fOrm is the core of ecological envi ronment of river basin ecosystem, and base for the diversity of biotic community. Water structures cause major changes to the river form in varies degree.de crease the diversity of biotic community and influence health and stability of river ecosystem, as a result the service function of the system might be reduced and human interest might be damaged.Thus water. works construction should emphasize protection and recovery of river fOrm diversity. alteration of our con cepts for engineering construction and consider the demand of a healthy river basin ecosystem while satisfying human demand.
