In this research, TFPW-MK (Trend-free Pre-whitening Mann-Kendall) test and BFAST (Breaks For Additive Seasonal and Trend) were used to determine trends in climate data and to detect abrupt changes within the trend and seasonal components, respectively. The results show that air temperature and precipitation increased southward along the Nujiang River and heavily negatively correlated with altitude. The regional difference in PCD was obvious and higher PCD values, more than 60%, were observed in the Nujiang River basin in Tibet Autonomous Region. Precipitation-concentration time (PCT) in the study area (except for Gongshan) mainly from late July to late August. Generally speaking, the Nujiang River basin has become warmer in the past decades. The annual mean air temperature increases at a rate of 0.36 ℃/10a. %U https://www.geog.com.cn/EN/10.11821/xb201205005
