摘要: 为更好的利用自然条件,人们往往根据一些指标对自然条件及农业、林业、牧业等进行分区。采用的指标不同,分区结果不一,而且指标的确定有一定的经验性,不利于进行多因子综合考虑。本文采用箍选因子最优分割法,将气候与农业产量结合起来区划,并对结果进行一些讨论。

Abstract: In this paper,the optimum dividing method of selecting predictors is used to link closely the climate and yield of agricultural products for dividing of regions,Jilin province is divided into five regions,namely;the western region, middle region,mountainous region,hill region and southeastern region.Statis_ tical verification has proved that these five crops,crop yields,and climate in these five regions are significantly different,but the division of regions is proper and desirable.At the same time,the yield index and the yield value index are suggested for the consideration of rational overall layout of crops in these five regions.
