基于生态系统健康的受损河流组合修复模式设计

随着经济发展及规模的不断扩大,河流生态系统已受到来自自然和人为因素的巨大压力,工农业及生活污染,水质不断退化以及超量引水等已严重损害了河流健康,尤其是城市河流生态系统空间的萎缩及系统的脆弱性,不当的水资源利用方式对河流生态系统产生的胁迫更加剧了河流生态的健康发展,缓解自然和人为因素对河流生态系统的压力,恢复城市的自然景观及人文景观已至关重要.本文基于河流复合生态特性及系统受干扰的因素影响分析,探讨研究了城市河流生态系统修复设计原则,并结合实际河流建立了相应的生态修复工程模式,为维护河流健康及生态景观提供技术参考.

Combined Ecological Restoration Scheme for Damaged River Based on Ecosystem Health Analysis

With the economic development and the scale increasing,the river ecosystem is seriously damaged by the natural and mankind activities and stress.The industrial and agricultural pollution and overburden exploration water had arose the ecosystem degradation,especially for the urban river ecosystem health.So to slow the ecosystem stress and renew the ecological landscape and utilize ecological restoration in urban rive is very important.In this paper,the design principle on river restoration is studied based o...
