| 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 inChina(excluding the cultivated genera coming from other countries),and indicates severalcharacters of geographical distribution:regional limitation,disjunction and extension. Through comparatively analysing the types of genera size and distribution types,it is foundthat 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 distribu-tion. With the increase of the importance of Leguinine plants in agriculture,forestry and a-groforestry in our country,this paper can provide a theoretical guidance for selecting theLegumine plants in a regional scope. |
