改进的灰色关联度在农业系统中的应用

Application of Revised Gray Incidence Degree in Agricultural System

在目前各种常用的灰色关联度模型中 ,都或多或少地存在一定程度的缺陷 ,针对这些缺陷 ,提出了一种新的关联度计算方法 ,并将其运用到松嫩盆地某县的农业系统中 ,从定量的角度考察了粮食产量与诸影响因素之间的相互关系 ,在此基础上提出该县今后农业的发展措施和对策 ;理论推导与计算结果同时表明 ,所提出的灰色关联度模型满足规范性和保序性要求 ,并且同常规数理统计方法计算的结果保持高度的一致性 ,对已有的关联度模型有较大的改进 ,具有良好的性质。表 2 ,参 4。

There are some limitations in the normal gray incidence degree more or less,this paper put forward a new revised gray incidence degree according to these limitations,and applies it in the agricultural system of a county in Songhuajiang-nenjiang basin,studies the relation between the grain production and factors influencing quantity,on this basis,the countermeasures are presented.The theory deduction and calculating result prove that the new revised gray incidence degree model satisfies the standard property and keeping order property,this method has significant progress than normal method and has excellent property.
