中文摘要：
利用新疆南疆地区43 个气象站1961-2013 年的逐月降水资料,通过计算降水量距平百分率和M-K 突变检验法对该地区降水量的时空变化特征进行了分析.结果表明：年降水量的突变点为1987 年,降水量总体呈升上趋势,降水量在时间上呈夏季〉春季〉秋季〉冬季的特点,在空间上呈现山区〉盆地（平原）〉沙漠地区的特点.
英文摘要：
On the bases of monthly meteorological data from 1961 to 2013 of south area of Xinjiang, this paper used anomaly percentage and M?K mutation test method to calculate and analyze regional precipitation changes. The results show that:a) precipitation mutation appeared in 1987;b) the overall trend in precipitation is rising, the seasonal precipitation trend is summer, spring, autumn and winter, regional precipitation trend of mountainous area is greater than that of basin area ( plain) and desert region.
