摘要
东北红豆杉是国家Ⅰ级重点保护野生濒危物种。通过对辽宁省现存东北红豆杉的地理分布特征、种群数量以及种群结构进行调查分析,结果表明:辽宁省天然东北红豆杉仅存60株;在5个区域呈相对集中分布;个体林木胸径分布在6cm以下;种群结构不均衡,通过自然繁育困难。亟待加强保护和人工促进种群恢复。
Taxus cuspidata is a national first-class key protected wild endangered species.The geographical distribution characteristics,population number ＆amp; population structure of Taxus cuspidata in Liaoning Province was investigated.Result shows that there are only 60 strains natural Taxus chinensis in Liaoning Province,relatively concentrated in 5 Area;the DBH of individual trees concentrate below 6 cm;the population structure is imbalance;natural breeding is very difficult,which calls for strengthened conservation to promoting population recovery and back to its original place.
