摘要
道路建设和路网的扩展影响着道路周边生态系统格局、结构和功能,其对区域生态安全的影响也受到了极大关注。从道路建设和道路网络本身的多尺度特征和所产生的生态效应入手,在分析了道路工程对土地利用影响的基础上,探讨了道路对区域生态安全的影响和道路的生态安全,指出道路景观尺度上的生态恢复是区域生态安全格局构建的合适尺度,并对道路工程的景观恢复途径做了进一步的探讨。
The construction and development of road networks affects surrounding ecosystem pattern, structure and function, the regional ecological security pattern causesd by the road networks attracts much more attention. After analyzing the multiple-scale property of road construction and road networks and their ecological effects, the paper focuses on the effect of road networks on regional ecological security pattern and points out the research contents. The study suggests that ecological restoration of road construction at landscape level is suitable scale for ecological security pattern. Furtherly, the procedures of landscape ecological restoration of road engineering project are discussed.
