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 nonparametric test, concentration index, wavelet analysis method. Result displayed that runoff and precipitation 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.
