| 摘 要： | 对河西地区不同地域和高程分布的 2 5个水文气象站点近 5 0年年降水量、年平均气温和年径流量趋势变化分析表明 ,该区年降水量、年平均气温和年径流量变化趋势存在明显的地域分布 ,并受海拔高程的影响。这些变化的产生可能为全球变暖和不同的下垫面影响所致。总体分析表明 ,该区气候趋于暖湿 ,这同 GCMs成果一致。

| Abstract: | To analysis the variance of the annual precipitation, annual runoff and yearly average air temperature of Hexi Region nearly 50-year, we used the datum of 25 Meteorological stations and Hydrologic stations which distribute at different altitude. The results showed that the general variance tendencies of annual precipitation, annual runoff and yearly average air temperature of Hexi Region were affected by the positions of the stations and their altitude. The climate of Hexi Region tended to warm and wet. The results agreed with that of other's such as GCMs. |
