摘要：

利用河南省107个气象观测站1961—2012年逐旬日照时数资料，分析河南省旬日照时数的时空变化特征，并利用去趋势波动分析方法探讨了河南省旬日照时数的标度不变性.结果表明：研究期间，河南省逐旬日照时数及其站间均方差的平均值分别为57.90和9.18h，其概率分布均不服从正态分布.河南省逐旬日照时数累积离差具有显著上升趋势，而逐旬日照时数站间均方差的累积离差具有阶段性变化特征，在阶段内均具有显著的线性变化趋势.河南省逐站旬日照时数的标度指数均在0.5以上，表明时间序列具有持久性.河南省旬日照时数标度指数空间变异性较小，具有正态分布的特征.

Abstract: Using the ten-day sunshine duration data of 107 meteorological stations in Henan Province from 1961 to 2012, spatialtemporal variation characteristics of ten-day sunshine duration were analyzed, and the scale invariance analysis of tenday sunshine duration was studied by using the method of detrended fluctuation analysis. The results showed that the means of tenday sunshine duration and its standardized error among stations were 57.90 and 9.18 h, respectively, and their probability distributions were not subject to normal distribution. The cumulative abnormal of sunshine duration had a distinct linear increasing trend, however, its square deviation among the stations was of phase characteristics. The scale index of ten-day sunshine of each station was above 0.5, indicated that time series of scale index was of permanence. Variation of scale index among stations was small, which obeyed the normal distribution.
