| 摘 要： | 文章采用Mann-Kendall非参数统计检验法对洮儿河流域1958-2006年水文气象要素进行了分析,结果表明:洮儿河流域1958-2006年各季节及年平均气温大多数都以显著增温为主；流域降水总体有减小的趋势,但是趋势不显著,冬季降水有微弱增加的趋势,从上游到下游降水减小幅度增加；河道年平均流量减少的趋势显著；各季节及年平均径流量减少的趋势十分显著,以夏季和秋季减少量最大.

| Abstract: | The Mann-Kendall nonparametric statistical test is used to analyze the hydrological and meteorological factor from 1958 to 2006 for the Taoer River basin.The results show that: the each season and the annual average temperature mainly increase from 1958 to 2006.There is a negative trend for basin precipitation,not significant.There is a weak obverse trend for winter precipitation.the decrease extent of the precipitation is gradually increased from upstream to downstream.There is a significant decreased trend for the river annual average runoff,and the reduction is largest in the in summer and autumn of each reason. |
