Abstract

Recently, extreme climate variation has been studied in different parts of the world, and the present study aims to study the impacts of climate extremes on vegetation. In this study, we analyzed the spatiotemporal variations of temperature and precip- itation extremes during 1960–2015 in the Yangtze River Basin (YRB) using the Mann-Kendall (MK) test with Sen’sslope estimator and kriging interpolation method based on daily precipitation (P), maximum temperature (T ), and minimum max temperature (T ). We also analyzed the vegetation dynamics in the YRB during 1982–2015 using Global Inventory min Modeling and Mapping Studies (GIMMS) normalized difference vegetation index (NDVI) datasets and investigated the rela- tionship between temperature and precipitation extremes and NDVI using Pearson correlation coefficients. The results showed a pronounced increase in the annual mean maximum temperature (T ) and mean minimum temperature (T ) at the rate of nav xav 0.23 °C/10 years and 0.15 °C/10 years, respectively, during 1960–2015. In addition, the occurrence of warm days and warm nights shows increasing trends at the rate of 1.36 days/10 years and 1.70 days/10 years, respectively, while cold days and cold nights decreased at the rate of 1.09 days/10 years and 2.69 days/10 years, respectively, during
