主 题:Air temperature Arctic Climate change Precipitation NDVI
摘 要:Climate warming leads to vast changes in the land cover types and plant biomass in the northern high-latitude *** overall trend is of shrubland and tree lines moving northwards,while changes in different land cover types and vegetation growth in response to climate change are largely ***,we selected land areas with latitudes higher than 50°N as the study *** compared the land cover type changes and explored relationships between the normalized difference vegetation index(NDVI)values of different land cover types,air temperature,and precipitation during 1982-2015 based on dynamic *** results indicated that forest and shrubland areas increased as a large area of grassland shifted to forest and *** snow/ice,tundra and grassland largely have decreased from 1982 to *** approximately 277.3×103 km2 of barren land(6.2%of the total barren land area in 1982)changed to tundra,the tundra area still decreased because some tundra shifted to forest and *** NDVI values of tundra significantly increased,but the shrubland showed a decreasing *** in the growing season(June to September)showed the largest positive correlation coefficients with the NDVI values of forest,tundra,grassland,and ***,due to shrubification processes and plant mortality in shrubland areas,the shrubland NDVI showed negative relationship with annual temperature but positively correlated with monthly *** together,although there is large room for improvement of the land cover type data accuracy,our results suggested that the land cover types in high-latitude regions changed significantly,while the NDVI values of the different land cover types showed different responses to climate change.
