高原区近自然河道生态治理模式研究及应用

Study and Application of Pattern of Ecology Harnessing of Near-natural River Bank in Plateau Region

随着社会经济的快速发展,人类对生态环境的需求和期望也越来越高,由于高原地区近自然河道自身的特点,单一的工程措施给当地生态环境带来了巨大的压力。本文在阐述高原近自然河道自然特性和生态河道治理内涵的基础上,从水利功能和生态功能的角度,提出了原生态型、工程生态型、生物修复型3种河道生态治理模式及不同模式适用条件,对高原地区河道的生态恢复、建设和管理具有一定的指导意义。

With rapid development of social economy,the human being has high need to ecological environment.Great challenges were brought to the local ecological environment because of the single engineering measures and near-natural river bank′s characteristics in plateau region.On the base of being described of near-natural river bank characteristics and governances,original ecology,engineering ecology and ecological recovery project were brought at the angle of water function and ecological function in this paper,which includes different modes of governance applicable conditions.This paper has certain guiding significance for ecological restoration,construction and management of near-natural river bank in plateau region.
