摘要： 本文对我国豆科植物属─主要指我国野生自产的属─的地理分布型进行了分析和总结,井阐述了豆科植物属在地理分布上的几个特性;区域局限性、间断性和扩散性。通过对属的大小类型与地理分布型的对比分析,发现热带成分属与属的大小类型关系密切。关于豆科植物的结瘤固氮特性,三个亚科是有区别的,这除了与遗传因素有关外,还与地理分布环境有一定关系。随着豆科植物在我国当今农业、林业及正在兴起并迅速发展的农林复合业(Agro-forestry)中重要性的增强,尤其对土壤改良和土地持续利用的贡献加大,本文对于在区域范围内选择豆科植物属种具有理论指导意义。

Abstract: This paper analyses and sums up the distribution types of the genera of Legumine in China(excluding the cultivated genera coming from other countries),and indicates several characters of geographical distribution:regional limitation,disjunction and extension.Through comparatively analysing the types of genera size and distribution types,it is found that the tropical composition of genera has a close relation with the gnera size.About the characters of nodulation and nitrogen-fixation,three subfamilies are different.They are related not only with the genetic factors but also with the geopgraphical distribution.With the increase of the importance of Leguinine plants in agriculture,forestry and agroforestry in our country,this paper can provide a theoretical guidance for selecting the Legumine plants in a regional scope.

Key words: Legumine, Genera, Distrbution types, Characters of nodulation and nitrogen-fix-ation
