利用1964-2012年艾比湖流域博尔塔拉河径流、降水数据，运用非参数检验、集中度、小波分析等方法研究了博尔塔拉河年径流量与降水量的集中性及多时间尺度相关关系。研究表明：博尔塔拉河年径流量及降水量均通过Mann-Kendall趋势检验，全年增加显著。通过Mann-Whitney突变检验，径流量与降水量分别在1996年和1985年发生了显著的增多突变。博尔塔拉河径流量集中度呈不显著的增加趋势，降水量集中度呈不显著的减少趋势。博尔塔拉河径流量的集中度存在6、11和14 a的周期变化，而降水量集中度存在12和18 a周期显著。博尔塔拉河年径流量与降水量存在多时间尺度的显著相关关系，并以正相关为主。

Using data of runoff and precipitation in Boertala river of Ebinur lake from 1964 to 2012,the paper studied concentrations index and correlation characteristics of runoff and precipitation by using non -parametric test, concentration index , wavelet analysis method .Result displayed that runoff and precipita-tion in BoErtala river significantly increase all over year and passed Mann-Kendall trend test .The abrupt change of runoff and precipitation occurred in 1996 and 1985 respectively through Mann-Whitney test of abrupt change .The concentration ratio of annal runoff shows insignicant increase trend ,and that of annal precipitation shows insignicant decreasing trend .The primary cycle of the concentration ratio of runoff are 6,11 and 14 years and that of precipitation are 12 and 18 years.There are significant correlation of multi-time scales between annal runoff and precipitation in Boertala river .
