| 摘 要： | 依据新疆阿克陶县气象站1960—2009年逐月日照时数以及与日照变化相关的水汽压、降水、云量等资料,利用气候统计方法分析了阿克陶县近50年日照时数年代际、年际和各季的气候变化特征及其变化原因.结果表明,近50年来阿克陶县的年、季日照时数均呈减少趋势.各季减少的气候倾向率不同,减少幅度最多的是夏季,最少的是春季.相关分析得出降水是影响阿克陶县日照时数变化的主要因子.

| Abstract: | By means of the observed data of sunshine duration in Akto County in recent 50 years, according to the data of precipitation, total cloud amount and low cloud amount in Akto County, the inter-decadal, inter - annual and seasonal climate change characteristics on sunshine hours are analyzed, and the climatic causes for the decreasing sunshine duration are discussed. The results show that, the decadal, annual and seasonal sunshine durations in Akto County showed a decreasing trend in the past 50 years, while the decrease of seasonally climatic tendencies are unlike, the most decreasing range is in summer and the least is in spring. Correlation analysis concluded that precipitation is the main factor affecting the Akto County sunshine hours change. |
