| 摘 要： | 利用喀什市气象代表站点1951 ～2012年平均气温、年最高气温、最低气温、降水量等数据资料,分析近62年以来喀什市的气温和降水量变化特征.结果表明,进入21世纪以后该地域气温明显提升,平均气温趋向上升;年平均气温升高率为0.279℃/10a.相比20世纪,近10年的气温变动提升了1.3℃;降水量变动趋势总体上不明显,线性变动倾向率为1.237 mm/10a;62年以来喀什市最高气温上升率与西北地区最高气温上升率保持一致,平均极端最高气温和最低气温同样是趋向升高.近10年的最高气温、最低气温与过去相比,分别上升0.6和1.2℃,对年平均气温的升高贡献最大的是最低气温的提升.

| Abstract: | Based on annual average temperature, maximum and minimum temperature, precipitation in meteorological representative stationsof Kashi City during 1951 -2012, the variation characteristics of temperature and precipitation were analyzed. The results showed that the av-erage temperature in the region is rising, especially after the 2000s, the temperature is increased significantly ; annual average temperature riseat the rate of 0. 279 ℃/ 10 a. There is an obvious change in recent 10 years, the average temperature increased 1.3 ℃ than of previous 50years; there is a significant rising trend in the average temperature. The precipitation changes in the whole city of Kashi is not very obvious,linear variation tendency of the average annual precipitation was 1. 237 mm/10a, 1974 was the period of maximum rainfall, precipitation is146.2 mm. The extreme maximum and minimum temperature of Kashgar City is rising on average since 1962, the increasing rate of the maxi-mum temperature in the region is consistent with the southern area of Xinjiang. The extreme maximum and minimum temperatures of recent 10years were increased 0.6 ℃ and 1.2 ℃ compared to the Fast 50 years. |
