摘要
利用贵州省19个气象站1961-2013年日照时数资料,运用趋势分析法、空间插值法、小波分析法对贵州省玉米与水稻各生长期的日照时数变化进行分析。结果表明:(1)贵州省玉米与水稻各生长期日照时数年际变化均呈下降趋势,年代际变化呈波动起伏趋势;(2)贵州省玉米与水稻各生长期日照时数变化的空间格局存在差异;(3)玉米播种-出苗期、拔节-抽雄期、灌浆-成熟期、总生长期日照时数变化第一主周期分别为22a、18a、29a、10a。水稻秧苗期、移栽分蘖期、拔节孕穗期、抽穗成熟期、总生长期日照时数变化第一主周期分别为15a、17a、13a、29a、11a。
Using the data of hours of sunshine based on 19 meteorological stations in Guizhou province from 1961 to 2013,and taking the method of tendency analysis,special interpolation and wavelet analysis to analyze the change of hours of sunshine during all growing season of maize and rice in Guizhou province.The results showed that:(1)The inter-annual change of hours of sunshine during all growing season of maize and rice taking a decline trend,and the change of period is fluctuant in Guizhou;(2)The hours of sunshine during all growing season of maize and rice taking a decline trend,and the spatial patterns were different in Guizhou province:(3)The main period of changes in hours of sunshine during the sowing-seedling period,jointing-tasseling period,grouting-ripen period and total growth period were 22,18,2910a separately;(4)The main period of changes in hours of sunshine during the seeding stage,tillering stage,jointing booting stage,heading stage and total growth stage were 15,17,13,29,11a separately.
