- Abstract:
- Based on 40 years climate materials of the mountainous and plain area, 20 years runoff materials of the three rivers in the Sangong River Basin, calculating and correlation analyzing the climate and runoff materials, the main results are as follows: the temperature of the mountainous and plain area shows a rising trend, the 1990s is the largest rising range of the temperature, and the winter is the largest rising range of the temperature in the seasons;the precipitation of the mountainous and plain area shows an increasing trend, the 1980s increases markedly, the autumn has the most precipitation in the mountainous area but the summer has the most precipitation in the plain area;the runoff of three rivers is centralized in the year and mainly appears in flood season, the runoff is little in winter and spring, the runoff was reduced from the 1980s to the 1990s and was reduced by 310.9×104m3;the precipitation in summer has much influence on the runoff of every seasons in the basin, but the season temperature changes has little influence on the runoff of the basin.
