摘要:

以吉林省梨树县为例,阐述了利用灰色系统进行玉米气象估产的方法,其中包括用GM(1,1)模型进行趋势产量预测,用灰色关联度分析方法确定主气象因子群,以及利用GM(1,N)进行气象产量预测等.

Abstract:

Taking Lishu County as an example, this paper states the way of maize yield estimation of meteorology by gray model, which includes the methods to forecast the tendency yield by GM(1, 1)model, to figure out the dominant meteorological factors affacting meteorological yield through gray-relative-degree analysis, to foreshow the meteorological yield by GM(1, N)and so on.
