针对环长白山旅游公路改扩建工程,以ETM+遥感影像为基础数据,提取公路经过区域各景观要素信息,应用景观生态学分析软件Fragstats3.3计算该公路不同距离缓冲区的景观格局指数,通过分析其变化规律,定量化地研究环长白山旅游公路改扩建对公路沿线区域景观格局的影响。结果表明,公路改扩建导致不同缓冲距离带内斑块密度、Shannon多样性指数、景观分割指数增加,蔓延度指数、最大斑块指数减小;公路改扩建前后各景观指数的变化幅度随缓冲距离的增加而减小。环长白山旅游公路改扩建加剧了路域景观格局破碎化,对景观格局影响集中表现在200 m范围以内。
According to the reconstruction and expansion project of Changbai Mountain Tourism Road, taking the ETM + remote sensing image as the basic data, we extracted the landscape elements information of the highway passing through the area and applied the landscape ecology analysis software Fragstats3.3 to calculate the landscape pattern index of the different distance buffer zones of the highway. The regularity of variation and the quantitative study of the influence of the Changbai Mountain tourist road reconstruction on the landscape pattern along the highway. The results show that the highway expansion and expansion leads to the increase of the patch density, Shannon diversity index, landscape segmentation index, the degree of spread index and the maximum patch index in different buffer distances. The change range of the landscape indices before and after the highway expansion and expansion increases with the buffer distance Increase and decrease. The reconstruction and extension of the Changbai Mountain Tourism Road has exacerbated the fragmentation of the landscape pattern of the road area, and the impact on the landscape pattern has been concentrated within a range of 200 m.
