摘　　要：分析了石河子地区位于不同海拔高度的3个观测站的降水资料,结果表明,石河子地区各地降水量分布不均,石河子年降水量最多,其次是炮台,最少是莫索湾。3站季节变化一致,均以春夏季降水量居多,约占全年63%,冬季降水量最少,约占全年的13%。降水量年际变化一致,70年代降水量偏少,80年代以后降水量偏多。出现丰水年和干旱年的降水趋势一致,且出现丰水或干旱时大面积发生的机率较大。By analyzing the three stations'data where are at different altitude,it is shown that the precipitation d is-tributes was unevenly:yeal precipi tation in shih ezi was maximum,paota i secondary,and Mosuowan least.Besides,the precipitati on varies by seasons.Spring and summer accounts for year rainfall about 63per cent,winter about 13per-cent.The rainfall in the 1970' s was less and b ecome more after in the1980' s .The trend of precipitation was con sistent in drought or plurial years,and the p robability with large scale occurre nce was bigger.
