英文摘要	This study used the Innovative trend analysis method, Mann-Kendall, and Sen's slope estimator test to investigate the mean annual precipitation, annual mean air temperature, and river discharge at selected stations of the sub-basin. The results showed that the trend of annual precipitation trend was significantly increased in Nizhneangarsk station (ф = 0.88 and Z = -0.64) and Bolshoe Goloustnoe (ф = 0.24 and Z = 1.14) whereas, the other stations showed a decreasing trend. The most decreasing trend was observed in the Ust Barguzin station (ф = -0.68, Z = -2.38, and beta = -0.95). The average air temperature has increased by 1.7 degrees C from 1970 to 2019. All stations showed an increasing trend of annual air temperature during the study period. The most increasing condition was observed in the Ulan Ude station (ф = 9.20, Z = 7.78, and beta = 0.04). The river discharge showed an increasing trend in Utulik River, Upper Angara River, and Barguzin rivers. The most decreasing is in the Selenga river gauge station (ф = -2.25, Z = -2.16, and beta = -2.96*). The warming rates in the Selenga river sub-basin of the study area were higher than those in the other four sub-basins and the global climate change more affects the semi-arid region.
