Correlation Analysis Between Fractional Vegetation Coverage and Land Surface Temperature in Agroforestry Ecotone
摘要
Abstract
Based on the eight Landsat images from 2000 to 2019,we used the spatial analysis,linear regression and spatial autocorrelation methods to analyze the spatio-temporal variation and correlation between fractional vegetation coverage(FVC)and land surface temperature(LST)on four different types of land cover in Harqin Banner,Chifeng,Inner Mongolia.The results show that①in the past 19 years,the FVC of Harqin Banner decreases from southwest to northeast,on the contrary,the spatial distribution of LST is lower in southwest and higher in northeast.②There is a negative correlation between FVC and LST.In the spatial correlation and linear regression,the correlation of farmland is stronger than forest,while the spatial autocorrelation of forest is stronger than farmland.③Compared with farmland,construction land and grass,FVC of forest can effectively reduce LST.When FVC is more than 0.75,it has the most obvious effect on LST.关键词
