摘 要: 水稻机械化生产的发展过程因受外部因素的干扰,呈现出非线性的特点。为此,利用3次指数平滑的时间序列法进行水稻生产综合机械化发展水平的预测,能排除外部的偶然干扰,平稳地反映出水稻生产综合机械化水平的发展趋势,取得较贴近实际的预测结果,为区域农业机械化的发展规划提供决策依据。 Disturbed by environment aspects, the development of rice mechanization is of un-linear tendency. To overcome these contingent aspects, a forecast method of 3-exponential flat was adopted to obtain such general development indexes smoothly. The procedure of this forecast had been proposed in the paper with a good result tallying with the fact of rice mechanization development in Guangdong province. This research work will be available in strategy decision-make project of agriculture mechanization design.
