Abstract:: Based on hydrological data recorded by Dalai Hydrologic Station and the same period of meteorological data by the 16 stations in area of Nenjiang River, we analyzed the climate change of spring thaw period from 1963 to 1988 and its influence on soil erosion. Results show that the trend of temperature appeared a downward trend and increasing trend of precipitation amount, with the average temperature of spring thaw period increasing. The average temperature and precipitation amount has a positive role on the increasing of the river runoff, but the effect of precipitation on river runoff was even more significant than temperature. Passing on the average temperature, precipitation, runoff (including snowmelt runoff) and sediment discharge to partial correlation analysis, spring thaw period of precipitation and river runoff on the impact of sediment discharge was even more significant and positive correlation with the average temperature was negatively correlated, but no significant impact.
