农机配套服务的系统分析和协调优化模型研究

在界定农机配套服务的基础上,首先系统分析了农机配套服务的影响因素,以黑龙江垦区51个农场近10年农机和粮食产量等数据为例,采用相关分析、建立最优模型等方法知目前黑龙江垦区农机配套比与粮食单产相关系数的绝对值存在逐年减少趋势.再以七星农场近10年数据为例知小型农机具配套比与粮食产量相关性最密切,而利用建立最优回归模型揭示大中型拖拉机配套农机具对粮食产量起到显著作用.最后建立和分析农机配套服务的协调优化模型,确定了决策变量的满足条件,为推进农机配套服务具有重要意义.

Study on Coordination Optimization Model and System Analysis of Agricultural Machinery Supporting Service

This paper,base on the definition of agricultural machinery service.Firstly,it analyzes systematically influence factors of agricultural machinery supporting services.Take data of farm machinery and grain yield and so on of Heilongjiang reclamation 51 farms near 10 year as the examples,use correlation analysis and establishes the most superior model, the result indicates correlation coefficient absolute value existences drop tendency between a complete set and the grain yield year by year in the Heilongjiang reclamation area farm machinery at present.Take the data of a Seven Star farm near 10 year as the example,we find there is closer relevance between the small agricultural machinery tools and the grain yield. The large and middle scale tractor agricultural machinery tools indicates the remarkable role to the grain yield by using the most superior regression model.Finally,satisfied condition of decision variables are determined by establishing and the analyzing coordinated optimization model of farm machinery necessary service.It has the vital significance in order to advance the agricultural machinery supporting serve.
