摘　　要：利用1951—2020年阜蒙县春播期降水量、平均气温、日照时数以及大气环流指数,应用多种方法分析了春播期气候特征及影响因子。结果表明:近70 a春播期及各月降水量和平均气温都呈现增加趋势,而日照时数则表现为总体减少趋势;降水量的主周期分别为52、44、34 a左右,分别在1954、1987和2005年发生了突变;平均气温的主周期分别为28、21、28 a左右,并没有突变情况的发生;日照时数的主周期分别为47、33、47 a左右,并分别在1954、1958、1960年发生了突变。春播期气候受诸多因素影响,其中降水量的影响因子有太阳黑子、WPSHAI、Niño 3.4指数,与其的相关系数分别为-0.268、0.371、0.054;平均气温的影响因子有WPSHAI、APVAI、AOI,与其的相关系数分别为0.371、0.473、0.372。Based on the precipitation,mean temperature,sunshine hours and circulation index during spring sowing period in Fumeng County from 1951 to 2020,the climatic characteristics and influencing factors of spring sowing period were analyzed by various methods.The results showed that in the past 70 years,the monthly precipitation and average air temperature during spring sowing period showed an increasing trend,the sunshine hours showed an overall decreasing trend.The main periods of precipitation are about 52 a,44 a and 34 a,and the mutation occurred in 1954,1987 and 2005.The main periods of mean temperature are about 28 a,21 a and 28 a,and there is no mutation.The main periods of sunshine hours are about 47 a,33 a and 47 a,and mutations occurred in 1954,1958 and 1960.The climate during spring sowing period is affected by many factors,among which precipitation is influenced by sunspot,WPSHAI and Niño 3.4,and the correlation coefficients are-0.268,0.371 and 0.054.The influencing factors of mean temperature are WPSHAI,APVAI and AOI,and their correlation coefficients are 0.371,0.473 and 0.372.
