Abstract
This paper analyzed on the variation characteristics of the annual average temperature, rainfall and sunshine times in Juye County during 1957-2014 using the method of linear analysis and Mann-Kendall examination. The result showed that the average temperature was 13.8℃and the annual average temperature increased by the rate of 0.13 ℃/10a in recent 58 years in Juye. Warming was a mutation phenomenon in the 1990s, specific starting in 1990. The annual average rainfall was 671 mm to show a clear downward trend at 17.9 mm/10 a and the interannual change was large. The largest difference was 762.5 mm between 2002 and 2003. The reducing precipitation mutation began in 1971 and surpassed the significant level of 0.05 in 1980. Annual sunshine hours decreased at rate 88.4 h/a and the trend was very obvious and the largest contribution to them was in summer and autumn. The abrupt change point of the sunshine time was in 1982 and the reducing trend was obvious after 1984.关键词
