摘要
对东阳市1957-2006年日照时数变化的分析结果表明:东阳日照时数总体呈下降趋势,20世纪90年代开始减少趋势更加明显,四季变化以夏季的减少趋势最大;从非线性动力学角度分析,其时间序列表现为一具有高复杂度的混沌轨迹。
Based on the analysis of variation of sunshine duration in Dongyang , Zhejiang -province , from 1957 to 2006, it shows that the sunshine duration in Dongyang overall assumes the declining trend, and the tendency to be more obvious from the 1990s. The declining trend during summer' s is the biggest in the four seasons. Based on the non - linear dynamics anal- ysis, the time series of sunshine duration indicated that the series has high performance for the complexity of chaotic trajecto- ries.
