摘要
首先通过对河南省木本植物科、属、种的统计与分析,总结出河南木本植物区系的性质与特征.接着探讨了就河南木本植物分布的地带性规律.在以上研究的基础上,结合河南木本植物地理区域分异的表现,对河南木本植物进行树种分区,共分2个带8个区,即A、北亚热带常绿、落叶林带:(1)大别、桐柏山地树种区;(2)伏牛山南坡山地树种区;(3)南阳盆地栽培树种区;(4)淮南平原栽培树种区.B、南暖温带落叶阔叶林带:(5)太行山地树种区;(6)伏牛山北坡山地树种区;(7)豫西黄土丘陵、台地栽培树种区;(8)准北平原栽培树种区.最后,对河南木本植物资源的保护以及合理开发利用提出了建议.
According to a statistical analysis of families,genera and species,this paper firstly summarizes the characteristics and features of arbors in Henan.Secondly,the author expounds the latitude,longitude and vertical zone regularities of the arbor distribution in Henan.Thirdly,in view of the floristic geographical differentiation of woody plants,the author divides the arbors into 2 belts 8 areas,as follow: Ⅰ.The evergreen-deciduous forest belt in the North subtropicas Ⅰ1.Mt.dabie-Tongbe area Ⅰ2.The south slope of Mt.huniu area Ⅰ3.Nanyang basin cultivated area Ⅰ4.Huainan plain cultivated area Ⅱ.The broad-leaved deciduous forest belt in the South warm temperature zone Ⅱ1.Mt.taihang area Ⅱ2.The north slope of Mt.huniu area Ⅱ3.The loess hilly tableland cultivated area in the north of Henan Ⅱ4.Huaibei plain cultivated area Finally,some proposals have been put forward for the protection,exploitation and utilization of the woody plant resources.
