海河流域平原河流生态修复模式研究Ⅰ--修复模式

Study on eco-restoration modes for plain rivers in Haihe River Basin Ⅰ: eco-restoration mode

由于水量不足、水质恶化及河流天然形态遭到破坏,海河流域大多数平原河流生态健康受到相当程度破坏。因而,对它们进行生态修复,需要建立相应生态修复模式体系对其进行指导。文中总结了现有河流生态修复技术,从中筛选出13种适宜于海河流域的修复技术。依据功能不同,将其分为水量调整技术、水质净化技术和生境改善技术3类。在此基础上,从影响海河流域平原河流生态健康的关键因素——水量入手,综合考虑河流水质与生境现状,提出海河流域平原河流生态修复模式体系。该体系包括4种修复类型(即管理保护、直接修复、补水修复和生态系统替代)和9种修复模式。

The eco-health of the most of the rivers on the Plain of Haihe River Basin are considerably damaged due to the water shortage,deterioration of water quality and destruction of the natural pattern;for which the relevant eco-restoration mode systems are therefore necessary to be established for guiding the eco-restoration therein.Based on the summarization of the existed eco-restoration techniques,13 restoration techniques suitable to Haihe River Basin are screened out and divided into three kinds,i.e.water a...
