淮河上中游流域日照时数时空分布特征OA北大核心CSCDCSTPCD
Characteristic of the temporal and spatial distribution of sunshine duration in the upper and middle reaches of Huaihe River Basin
为揭示淮河上中游流域日照时数时空变化特征及突变情况,基于1960-2014年日照时数资料,采用气候倾向率、Mann-Kendall趋势与突变检验、滑动t检验、克里金插值等方法,对流域日照时数的时空变化特征进行剖析.结果表明,淮河上中游流域近55年来日照时数以20世纪80年代为界由多变寡,其中年日照时数大约每10 a减少102.2 h,四季日照时数的气候倾向率排序为夏[-48.8 h/(10a)]、冬[-29.3 h/(10a)]、秋[-19.7 …查看全部>>
In order to reveal the spatial-temporal variation characteristics of sunshine duration in the upper and middle reaches of Huaihe River Basin and determine the year of mutation,we adopted such methods as the climate tendency rate,Mann-Kendall trend and mutation test,sliding t test,and Kriging interpolation,and analyzed the spatial-temporal variation characteristics of sunshine duration based on the data of sunshine duration from 1960 to 2014.The results indic…查看全部>>
