和田河典型站点气象因子变化特征及其对径流的影响
Meteorological Factor Change Characteristics and Its Effects on Runoff at Typical Sites of Hetian River
【摘要】 通过对1980—2013年数据资料分析得出,同古孜鲁克站年降水量呈现明显增加趋势,增加率为18mm/10a;年平均气温呈0.232℃/10 a的上升趋势,2007年出现最高气温,最低气温出现在2012年;年日照时间呈以倾向率为21.5 W/(m~2·10a)的速度减少趋势;年径流量以23.5×10~7 m~3/10 a的速率增加。分析径流与气象因子之间的关系可知,径流与前期气温的相关性强于降水,气温升高对径流的影响高于降水增加的影响。前期气温增加会加快冰雪融化,对径流量产生直接的影响。
【Abstract】 Through the analysis of data from 1980 to 2013:Tong Gu Mu ZiKe station annual precipitation showed a significant increase trend,the increase rate was 18 mm/10 a,The annual average temperature was0.232℃/10 a upward trend,the highest temperature appeared in 2007,the lowest temperature appeared in 2012,the decreasing trend of annual sunshine hours was 21.5 W/(m~2·10 a),The annual runoff was increasing at a rate of 23.5×10~7 m~3/10 a.Analyzed the relationship between runoff and meteorological factors have concluded that the correlation between runoff and antecedent temperature is stronger than that of precipitation,and the influence of temperature rise on runoff is higher than that of precipitation.Early temperature increase will accelerate the melting of snow and ice,and has direct impact on runoff.
