北京濒危植物丁香叶忍冬生态特征初步研究

The research of characteristics of Lonicera oblata

为科学保护濒危植物丁香叶忍冬,对其自然生态环境和生长状况进行初步研究,主要对海拔高度、光照条件、温湿度条件、群落组成结构、人为影响、植株生长、开花特征进行观测。结果显示,丁香叶忍冬在松山已经处于极度容易灭绝状态。对现存植株需进行严格保育,亟待增加种群数量,且有必要对其开花、传粉、结实生物学机制进行研究。

Being endangered plant in Beijing, Lonicera oblata was included in the List of Key Protection of Plant Species in Beijing, with only two individual plantlets growing in Beijing Songshan National Nature Reserve. In order to efficiently protect the species, we firstly investigated its environmental factors, carried out a preliminary research on its biological characters, which involved altitude of location, illumination, temperature, humidity, community, disturbing from human and sexual propagating characters. The results indicated that Lonicra oblata in Beijing was in peril of extinction. It is suggested that habitat improvement needs to be conducted, the population quantity should be rapidly increased and its biological mechanism of flowering and pollination would to be studied.
