河南栎林的研究

Study on Oak Forest in Henan Province

研究了河南栎类植物(共3属、含27种及变种)的区系组成。其中东亚—东西伯利亚分布种3个,占总数的11%;东亚分布种14个,占52%;中国特有分布种10个,占37%。河南栎林的主要类型有:栓皮栎林、麻栎林、短柄枹林、槲栎林、锐齿槲栎林、橿子栎林。它们是组成河南落叶阔叶林的主要成分。作者分析、研究了各种栎林的种类组成、结构、发展演替特点及其分布规律。

The floristic element of oak plant (including Quercus, Castanopsis, Cyclobalanosis, 27 species and variety) distributed in Henan province was analysed. the results showed that: there were 3 species of East Asia—East siberia distribution pattern, which took up 11 per cent of the total species; 14 species of East Asia distribution pattern taking up 52 per cent of the total species; 10 species of China endemic distribution pattern, 37 per cent of the total species. By analying the date chiefly obtained from our field survey, we recognozed that the main types of oak forest in Henan porvince are Quercus variabilis forest ,Q. acutissima forest, Q. serrata var. brevipetiolata forest,Q. aliena forest, Q. aliena var. acuteserrate forest, and Q. baronii forest. they are the main component element of deciduous broad-leaved forest in Henan province. Further, we had analysed the species component, the characteristics of structure, development succession and distribuction of oak forest in Henan province.
