生态理念在步道设计中的实践

基于普达措国家公园生态地位的重要性提出其步道设计的生态理念：充分利用和改造原有历史性路径，尊重场地现有地形地貌；尊重原有生物的生存环境，减少对其栖息地的破坏或干扰；尽量就地取材，采用天然材料，减少废弃物产生；采用简单生态的施工工法，以最少的人为干扰完成步道建设。重点阐述步道设计中深入贯彻生态理念的生态路面、架空栈道、生态木桥等典型设计，充分体现了尊重自然、保护优先、与环境相融的设计原则，为各类保护地内的步道设计与管理工作提供借鉴。

Practice of Ecological Concept in Footpath Design

Based on the importance of the ecological status of Pudacuo National Park, this paper put forward the ecological concept of the footpath design: utilizing and transforming the original historical path and respecting the existing topography; respecting the living environment of the original living beings and reducing the damage or interference to their habitats; using local and natural materials to reduce waste generation; adopting ecological construction method to complete the footpath construction with minimum human interference. This paper focused on typical designs of ecological pavement, elevated trestle road and ecological wooden bridge, which thoroughly implemented the ecological concept in the design of footpath, fully embodied the design principles of respecting nature, giving priority to protection, and integrating with the environment, and provided reference for the design and management of footpath in various protected areas.
