In order to master the characteristics of runoff changes in the Fuchunjiang River Basin,a scientific analysis of the impact on water resources is made from the perspective of climate change.The annual and inter-monthly characteristics of runoff in the basin were analyzed by using the flow data from 1969 to 2016. At the same time,based on the rainfall data of 18hydrological stations and meteorological element data of 8 meteorological stations in the river basin,the response of runoff and precipitation,temperature and evaporation factors to runoff was analyzed.The runoff of the Fuchunjiang River Basin has undergone two periods of transition from the end of the 1960 sto the present,and it is currently entering the third period with waterabundant years.The interannual variation of annual precipitation was consistent with that of runoff,and the rainy period corresponded to the partial peak period of runoff,and the less rainy period corresponded to the partial dry period.Precipitation is the most important factor affecting runoff in the Fuchunjiang River Basin. The impact of temperature factor on runoff only reached a significant level in July and August,and the annual evaporation had a significant negative correlation with annual runoff,which had a certain effect on the reduction of runoff.The results of this study can provide the reference for the optimal development and rational utilization of water resources in Fuchunjiang River Basin.
