基于廊道的结构特征论河流生态廊道设计

The Design of River Ecological Corridor Based on the Structural Features of Corridor

河流生态廊道具有提供水源、控制水和矿质养分的流动、过滤污染物、为物种迁移提供通道、维持生境多样性和物种多样性等多种功能。合理设计河流生态廊道,是解决当前人类剧烈活动造成的景观破碎化以及随之而来的众多环境问题的重要措施。从廊道的结构特征出发,对河流生态廊道的基本设计原则进行探讨,指出河流生态廊道的设计应以有效完成其功能为前提,在实际设计中应综合遵循适宜的廊道宽度、增强廊道的连通性、提高景观空间异质性等原则。

River ecological corridor have many functions such as providing water, control the flow of water and mineral nutrients, contamination filtration, provide migrating channel for species, maintain habitat diversity and species diversity. As impoitant measures, reasonable design river ecological corridors can be used to reduce the negative impact of landscape fragmentation. Starting from the structural characteristics of corridor, discussed the basic design principles of river ecological corridor. Summarized effectively completed functions of river ecological corridor shall be as the premise of the design, follow many principles such as the suitable corridor width, enhance connectivity of corridor, improve landscape heterogeneity, and puts forward comprehensive consideration above mentioned Drincilales in practical design.
