As an international river, the climate change research in Heilongjiang River Basin can provide references for sino-Russia cooperation in tackling climate change. Using the long-term daily measured data from 44 meteorological stations in the Heilongjiang River Basin, the spatial-temporal characteristics of the temperature in the past 59 years were analyzed. The results show that the temperature in the Heilongjiang River Basin has increased significantly and passed the significance test of 0.99. The abrupt change occurred in 1986. The climate change also showed multiple cyclical changes of 16-years, 8-years, and 4-years. The spatial distribution of the annual average temperature of the river basin is generally gradually decreasing from the south to the north as the latitude rises. There is also a spatial difference in the annual temperature increase, but all of the basin have passed the significance test of 99%.
