| Abstract: | To analysis the variance of the nearly 50-year annual precipitation,annual runoff and yearly average air temperature of Hexi region,the data from 25 meteorological stations and hydrologic stations in the region with different altitudes were used.The results show that the general variance tendencies of annual precipitation,annual runoff and yearly average air temperature of Hexi region are affected by the positions of the stations and their altitudes.The climate of Hexi region tends to be warm and wet.The results agree with those of other's such as GCMs. |
