山东省玉米气象产量分离方法的多重比较分析
Multiple Comparative Analyses of Separation Methods for Meteorological Yield of Corn in Shandong Province
摘要
Abstract
Corn is one of the major food crops in Shandong Province.It has great significance to explore the influences of meteorological conditions on the yield of corn in Shandong Province.In this paper,the relat-ed data of corn production in Shandong Province were used to fit the trend yield by 5a sliding average method, double exponential smoothing method,regression analysis and HP filtering method respectively,and then the meteorological yield was separated out.By using SPSS correlation and variance analysis,the significant degree of the four methods for fitting the trend yield and the accuracy of separating meteorological yield were com-pared.The results showed that all the four methods could better fit the trend yield,but the accuracy of meteor-ological yield separation was different.The accuracy of the four methods was ordered as HP filtering analysis >regression analysis >5a sliding average method >double exponential smoothing method.关键词
