中文摘要:
      为明确路网的形成与发展对生境的切割作用及对周边景观生态系统的影响,进行道路网景观尺度生态影响研究。基于内蒙古呼伦贝尔市多期遥感影像数据和路网矢量数据,应用景观格局分析法,对该地区1988—2015年间4个时期道路网及其影响区内景观格局的变化进行了研究,分析了道路网形成和加密过程中,邻近道路网不同距离缓冲区内景观格局的时空变化。结果表明:(1)随着路网加密,路侧空间结构变得复杂,斑块密度增大,平均斑块面积减小,破碎化程度加深,原有相对单一的景观类型由于路网形成带来的人类活动增加而变得多样;(2)路网两侧不同距离内景观指数的变化均在200~300m缓冲区内出现拐点,可能是由道路建设或路网形成导致。根据研究结果,推测路网对周边景观生态系统的影响范围可能在路网两侧距离300m以内。
英文摘要:
      To clarify the impact of formation and development of road network on habitat cutting and surrounding landscape ecosystem, the ecological impact of road network on landscape scale was researched. Based on multi-period remote sensing image data and road network vector data of Hulunbuir, Inner Mongolia, and using the landscape pattern analysis method, the road network and landscape pattern changes in the affected area during four periods from 1988 to 2015 was studied; the temporal and spatial changes of landscape pattern in the buffer zone at different distances from the adjacent road network were analyzed during the formation process of road network. The results show that: (1) with the development of road network, landscape of the research area has undergone a severe fragmentation, the road side spatial structure becomes more complex, the patch density increases, and the average patch area decreases; the natural single landscape has become diverse because of the increase of human activities brought by the formation of road network; (2) landscape index that at different distances from the road network has a significant change in the 200~300m buffer zone, which may be caused by the formation of the road network. It is inferred that the influence range of the road network on the surrounding landscape ecosystem may be within 300m.
