摘要
为研究风景名胜区植被时空变化及其影响因素,以泰山名胜区为例,基于1988—2018年长时序的Landsat影像数据,计算研究区NDVI,分析植被覆盖的时空变化特征,并结合气候、旅游等数据探索影响区域植被变化的因素.研究发现:1988—2018年间研究区植被整体呈波动下降趋势.空间上,植被退化的面积大于植被增长的面积,在主要景点及旅游路线附近,NDVI明显降低.影响因素方面,气候对植被覆盖度的影响不显著;旅游活动的影响表现为研究区内游客人数逐年上升,旅游活动增强,NDVI呈下降趋势,旅游活动是NDVI随时间变化的主要因素.
In order to study the spatio-temporal variation of vegetation in scenic area and its influencing factors,taking the Mount Tai scenic spot as an example,the NDVI of the research area was calculated based on the long-time Landsat image data from 1988 to 2018,and the spatio-temporal variation characteristics of vegetation coverage were analyzed.Combined with the climate,tourism and other data of the study area,the factors affecting vegetation changes were analyzed.The study found that the vegetation of Mount Tai scenic spot showed an overall trend of decline from 1988 to 2018.In space,the area of vegetation degradation is larger than the area of vegetation growth.NDVI is significantly reduced near major attractions and tourist routes.In terms of influencing factors,climate has no significant effect on vegetation coverage.The impact of tourism activities is shown as the number of tourists in the study area increases year by year,tourism activities increase and NDVI decreases.So the tourism activities are the main factors of NDVI changing with time.
