八角莲的生境及生物学特性对中国特有濒危药用植物小檗科（Berberidaceae）的5个居群进行了调查，每个居群调查2 ~ 3个5 m × 5 m的样地，取样点分布在四川、湖南、湖北、云南白药主要生长在万年青落叶阔叶混交林或竹林中，上层树种多为当地优势种，土壤为黄棕壤，pH值5.40- 6.59，有机质含量丰富速效N、P、K和全N、P、K含量高分别为840，46，310 mg kg-1和9970，1217，2603 mg kg-1，繁殖干扰和人类的过度开发使该植物濒临灭绝。原地保护被认为是这种植物的保护策略。
The habitats and biological characteristics of Dysosma versipellis(Hance) M.Cheng(Berberidaceae),an endangered medicinal plant endemic to China,was investigated.Two or three sampling plots with 5 m × 5 m each were surveyed for each of the five populations.The sampling sites were distributed in five provinces,i.e.Sichuan,Hunan,Hubei,Jiangxi and Anhui.D.versipellis grows mainly under evergreen and deciduous broadleaved mixed forest or in bamboo forest.Most trees in upper layer were dominant local species.The soil was yellow brown earth,pH 5.40-6.59,with rich organic matter(19.36%),and high available N,P,K and total N,P,K contents(840,46,310 mg kg-1 and 9 970,1 217,2 603 mg kg-1,respectively).Propagation disturbance and human overexploitation cause the plant to be endangered.Ex-situ in combination with in-situ protection is thought to be a conservation strategy for this plant.
