Abstract
Based on the data of annual precipitation and seasonal precipitation of Karamay from 1957 to 2010 , the paper used non parametric statistical test of Mann -Kendall and R/S method and the least square method analyzed the trend and Hurst index of average annual precipitation and season precipitati -on, and estimated the variation trend and sustainable features of future precipitation .The results showed that the average annual precipitation of Karamay has significantly increased , but the persistence of the in-crease is not strong;the trend of spring and autumn precipitation is similar with persistent of annual pre -cipitation , summer precipitation has a decreasing trend and persistent;winter precipitation has a decrea-sing trend, but the decreasing trend is random .关键词
