摘    要:利用R/S分析研究了农业发展的总趋势.农业发展的长期变化过程既带有趋势变化成分,又带有周期变化成分,还带有随机变化成分,因而根据趋势变化分析、周期变化分析和随机变化分析集成的方法来预测农业发展是可行的,提出的集成预测模型的拟合误差比单一模型的拟合误差小,预测效果比较好,是农业发展预测的一条比较有效的途径.

关 键 词:农业发展  R/S分析  趋势变化  周期变化  随机变化  集成模型

Abstract:The total tendency of agricultural development is researched by means of R/S analysis.There are tendency,period and arbitrary fluctuation compositions in the process of long-term fluctuation of agricultural development.Hence it is feasible that agricultural development is forecasted by means of comprehensive method of tendency,period and arbitrary fluctuation analysis.Calculation error of comprehensive forecast model put forward is smaller than that of single model,and forecast result is comparatively ideal,which is a relative efficient way of forecast of agricultural development.
Keywords:agricultural development  R/S analysis  tendency fluctuation  period fluctuation  arbitrary fluctuation  comprehensive forecast
