河南省分布的常绿阔叶植物在郑州市和北京市的栽培现状分析

河南南部山区是郑州市和北京市栽培常绿阔叶植物的重要种源地,郑州市栽培的类群分别为14科、19属、28种,占总科、属、种的77.8%,57.8%,56.0%,占其国内科、属、种比例的77.8%,61.3%,66.7%;北京市栽培的9科、12属、15种,占总科、属、种的69.2%,63.2%,53.6%,占其国内科、属、种比例的75.0%,66.7%,71.4%.河南省大别山、伏牛山、桐柏山是两市栽培常绿阔叶植物的集中野生分布区;海拔与常绿阔叶植物北引距离有密切关系.建议以海拔700 m和1 200 m以下分别作为郑州市和北京市从河南栽培野生常绿阔叶植物的重要依据.

Analysis on the Current Cultivation Situation of Wild Broadleafed Evergreen Plants from Henan in Zhengzhou City and Beijing City

The southern mountains in Henan are the important original areas of the broad-leafed evergreen plants introduced and cultivated in Zhengzhou City and Beijing City.Among them,there were respectively 14 families,19 genera,28 species introduced and cultivated in Zhengzhou City and 9 families,12 genera,15 species in Beijing City which were wildly distributed in Henan.Funiu Mountain,Dabie Mountain and Tongbai Mountain were the concentrated wild areas of the broadleafed evergreen plants introduced and cultivated in the two cities.There was close relationship between the altitudes in wild environment and the distances of introduction to north area.The altitude of 700 m and 1 200 m should be the important standands of introduction of broadleaved evergreen plants from Henan to Zhengzhou and Beijing,respeetively.
