应用景观生态学原理构建城市河道生态护岸

首先分析了传统水工设计中护岸的弊端，然后从景观生态学角度介绍了岸坡生态系统的主要特征、生态护岸的多种功能和景观生态学内涵；介绍了国内外生态护岸的研究现状，提出了城市河道在生态护岸设计中应在保证稳定安全的前提下，坚持生态优先的原则，重视其景观性和亲水性；最后对生态护岸的材料与植物群落的选择进行了分析。旨在探讨河流生态治理的方法,为生态护岸的构建与河流、洪泛区的治理提供一定的思路和参考。

APPLICATION OF LANDSCAPE ECOLOGY IN CONSTRUCTION OF NATURAL RIVER LEVEE

The authors analyzed disadvantages in traditional designing and building of natural river levees at first,and then briefly introduced the ideas of ecological management for the stream corridor.In particular,the constitution and characteristics of ecosystem in natural levee,and multi-functions and landscape connotation of natural levee are introduced.It was suggested that in designing and building natural levees,on the premise of security and stability,the construction and protection of ecosystem should be put in the first place,and the landscape and water affinity of natural levees should also be recognized.The selection of construction material vegetation communities was also analyzed.This paper can provide some ideas to specific projects such as construction of natural levee and management of stream corridor and flooded area.
