本文运用多元统计方法,将山西省种植大豆地区,划分为三大生态区八个亚区;同时研究了大豆生态类型在生态区中的分布。研究表明:山西省气候生态环境复杂,区划只能分块不能分带。大豆生态类型的分布具有明显的地域性,但一个区中可以种植若干个生态类型,且随着生态区由北向南的推移,各区所包括的类型渐趋复杂。分析表明:多元分析方法是大豆生态分类与分区的一种行之有效的方法,也可运用于其他作物。
In this paper, the multivariate statistical method is used to divide the planted soybean in Shanxi Province into eight sub-regions in the three major ecological regions. Meanwhile, the distribution of soybean ecological types in the ecological regions is also studied. Research shows that: Shanxi’s climate and ecological environment is complex, zoning can only be divided into blocks can not be zoned. The distribution of soybean ecotypes is obviously regional, but several ecological types can be planted in one area. As the ecological area moves from north to south, the types included in each area become more complicated. The analysis shows that the multivariate analysis method is an effective method for soybean ecological classification and zoning. It can also be applied to other crops.
