三江平原生长季植被覆盖时空变化及其对气候变化的响应
Spatiotemporal Variation of Vegetation Cover During the Growing Season in the Sanjiang Plain and Its Response to Climate Change
摘要
Abstract
Based on the remote sensing data from 2000 to 2020,as well as temperature and precipitation data,this paper evaluated the tempo-ral and spatial variation of NDVI in the growing season and its response to climate change in the Sanjiang Plain and different vegetation types by correlation analysis and other methods.The results showed that the average NDVI and NDVI of each vegetation type in the growing season in the Sanjiang Plain from 2000 to 2020 showed an upward trend,and the forest had the largest upward trend(0.016 2/a).The annual tempera-ture and precipitation in the Sanjiang Plain showed an upward trend,the temperature in the growing season showed a downward trend and the precipitation showed an upward trend.The spatial distribution pattern of NDVI in the growing season of 2000,2005,2010,2015 and 2020 in the Sanjiang Plain was generally similar,and the vegetation cover showed an overall improvement trend.In the growing season,the vegetation growth was good,and the medium(0.4<NDVI<0.6)and high(NDVI≥0.6)vegetation coverage accounted for 98.22%of the whole area.During the growing season of the Sanjiang Plain from 2000 to 2020,vegetation NDVI was negatively correlated with temperature and positively correlated with precipitation,indicating that the increase of temperature in this region mainly inhibited vegetation NDVI in the growing season,and the increase of precipitation mainly promoted vegetation NDVI in the growing season.关键词
