长江干线生态航道建设探析

Analysis on Ecological Channel Construction of the Yangtze River Main Route

以往的航道整治工程在有效改善航道条件的同时,也在一定程度上破坏了河流生态环境.在我国大力推进生态文明建设及长江经济带发展成为国家重大战略的背景下,航道生态化建设成为航道开发的趋势和要求.深入探析了生态航道概念、生态目标及相应建设任务.梳理了近年来长江干线生态航道建设采用的主要生态技术及其应用现状,其中包括生态护岸、生态护滩、生态坝体和人工鱼巢等.最后,对其理论研究和工程实践层面有待深入探究的五方面内容进行展望,旨在为进一步推进内河生态航道建设提供借鉴.

The previous waterway regulation projects have destroyed the river ecological environment to some extent while effectively improving the waterway conditions.Under the background that China vigorously promotes the construction of ecological civilization and the development of the Yangtze River Economic Belt has become a major national strategy,the ecological construction of waterway has become the trend and requirement of waterway development.The ecological waterway concept,ecological objectives and corresponding construction tasks are deeply analyzed.The main ecological technologies and their application status of ecological channel construction of the Yangtze River trunk line in recent years are summarized,including ecological bank protection,ecological beach protection,ecological dam body and artificial fish nest.Finally,the five aspects of theoretical research and engineering practice that need to be further explored are prospected.The aim is to provide reference for further promoting the construction of inland river ecological waterway.
