摘要

边界划分是国家公园保护与管理的重要手段,通常以行政区和自然地理边界为参考,借助人工干预的方法进行划分,而较少考虑当地生态系统的完整性以及人为干扰因素,造成边界划分不合理、不清晰。本研究以钱江源国家公园体制试点区中横岭角和古田山访客中心2处干扰较大的典型区为例,用无人机近低空遥感技术结合实地植被调查,评估现有功能分区。结果表明,横岭角和古田山访客中心功能分区修正面积分别为53,550m~2和19,667 m~2,分别占航拍研究区域面积的29.75%和16.39%。功能分区不合理划分的原因包括:(1)人为干扰较大的区域与自然地物较难分辨;(2)部分边界划分没有考虑生态系统的完整性,将面积较小或完整性稍差的天然林划分为保护级别较低的区域。本研究采用航拍影像结合地面调查,从保护当地生态系统完整性和减小人为干扰因素的角度出发,为国家公园功能分区边界划分与细化提供一种合理可行的方法。
        Delineating areas within a national park for different uses and management plans is important for protecting the land. Functional zones may be designated based on administrative boundaries, natural geographical boundaries, or a manual survey. However, the current delineation practice barely considers the integrity of the local ecosystem or human factors, which results in unreasonable and unclear boundaries. Considering two typical areas with large human interference in Qianjiangyuan National Park pilot as an example, we employed both low-altitude unmanned aerial vehicle(UAV) remote sensing technology and on-the-ground field vegetation surveys to evaluate the legitimacy of the already established functional zoning boundaries. The results show that 53,550 m~2 and 19,667 m~2 of the functional area surrounding Henglingjiao and Gutianshan Visitor Center had been modified,respectively, accounting for 29.75% and 16.39% of the aerial study area. Misclassification of functional zoning may occur due to(1) difficulties in distinguishing between areas with large human disturbances and natural features; and(2) partitioning the natural forests into small sections that do not consider the integrity of the vegetative system, which results in lower levels of protection. This study uses a combination of aerial imagery and ground surveys to provide a reasonable and feasible method for the future identification and refinement of functional boundaries in national parks so as to best protect local ecosystem integrity and to reduce human disturbance factors.
