景观生态学原理在河道生态岸堤构建中的应用

Application of Landscape Ecology Principle in River Levee Construction

分析了传统水工设计中岸堤(岸坡)构建的弊端,简要介绍了国内外学者在河流的生态整治方面的思想与观点。从景观生态学的角度着重介绍了岸堤(岸坡)生态系统的组成和主要特征、生态岸堤的多种功能和景观生态学内涵;提出了在生态岸堤设计中的坚持生态优先,同时重视景观性和稳定性;根据使用材料的不同对岸堤进行分类,对生态岸堤的植物群落的构建进行分析。可为生态岸堤的构建、河流、洪泛区的治理提供一定的思路和参考。

The disadvantages in the levee design of traditional hydraulic engineering are analyzed, and the ideas of the ecological management of rivers are briefly introduced in the paper. In particular, the components, characters, and the multi-functions of natural levee ecosystem and the connotation are introduced from the view point of landscape ecology. This paper suggests that in the design and building of natural levee, ecosystem should be put in the first place to be considered, and at the same time we should pay attention to landscaping and stability of natural levee. The paper also classifies the levees according to construction material, and analyses the construction of vegetation communities. This paper can provide good ideas for projects of construction of natural levee, and mana -gement of the river and flooded areas.
