摘 要：[Objective] The research aimed to analyze variation characteristics of the temperature and precipitation in north slope area of the Western Tianshan in recent 50 years.[Method] According to temperature and rainfall data from 1961 to 2010 at three meteorological stations in north slope area of the Western Tianshan,climate change in the zone in recent 50 years was analyzed by using linear trend analysis method and 5-year sliding average method.[Result] The temperature in north slope area of the Western Tianshan showed significant warming *** annual average temperature significantly increased at 0.3 ℃/10 a in recent 50 *** rise rates of the temperature in different seasons were different:autumn winter spring *** annual rainfall in north slope area of the Western Tianshan in recent 50 years overall presented relative increase *** from annual rainfall,it significantly increased at 16.9 mm/10 *** from seasonal rainfall,except in autumn,rainfalls in other three seasons in the past 50 years all showed significant increase trends,with amplitude of 3.2-11.2 mm/10 *** largest increase amplitude was in *** a small precipitation peak in the 1980s,autumn rainfall slightly declined in the past 20 years.[Conclusion] The climate in north slope area of the Western Tianshan become warm and wet.
