| 摘 要： | 河道水流特性主要包括水位、流量、流速及其分布、动水压强等,水流特性与河床的边界条件密切相关,而河床边界又是联系河道水流与生态系统的载体与纽带。本文从河道水流特性与生态环境之间的关系入手,阐述了河道水流特性对水生生物的影响,分析了水生生物生长状况的变化所导致的水流环境的变化。论述了河道中的局部建筑物(闸坝工程)在除害兴利、造福人类的同时,给河道生态环境带来的负面影响,河道的渠化和改道造成生态环境多样化的减少乃至消失。从河道水流特性与生态系统协调发展、人与自然和谐共处的角度,给出了河道生态修复的基本原则及措施。本文对于水利工程的规划设计、河道整治、生态修复、环境保护等领域具有一定的实践指导意义。

| Abstract: | The paper explained the effect of properties of river flow on aquatic organism and analyzed the change of flow environment caused by the change of growing status of aquatic organism,based on relation between properties of river flow and biological community.It also addressed the negative effect of hydraulic structures(dam and sluice) on ecological environment and the reduction or even disappearance of diversity of ecology environment caused by channeling and course changing of rivers in addition to the role they played in harm removing and benefit promoting to human being.It put forward the fundamental principles and measures for rehabilitation of river ecology in terms of harmonic development of properties of river flow with ecological system and harmonic coexistence of human with the nature.It is helpful to project planning,river treatment,ecological rehabilitation and environment protection |
