基于复合生态系统的城市河流环境影响指标体系及生态修复模式

Index System of Environmental Impact and Ecological Restoration Model for Urban River Based on Social-economic-natural Complex Ecosystem

阐述了环境影响指标体系的建立原则及识别方式,建立了基于城市河流复合生态系统的环境影响指标体系和环境影响的综合评估体系,探讨基于复合生态系统的城市河流生态修复的适用模式,恢复和维持城市河流良好的生态系统,对保证城市河流资源、景观、环境、社会经济的协调发展具有重要意义。

In this paper, environmental impact of urban river ecosystem is expatiated, and some principles for index system and identification of environmental impact from urban river ecosystem are analyzed from the aspect of ecosystem function and structure and adaptation ability. And the index system is used to evaluate environmental impact from Huangliangang River which is a representative urban river in Daye City, Hubei Province, suitable ecological restoration models for it are put forward based on its ecosystem function, natural and social function of social-economic-natural complex ecosystem of urban river.
