摘 要：
兰坪虫草是新近发现的冬虫夏草近缘种,具有较高药用价值,其野生资源逐年减少,有必要加强保护研究。本研究从兰坪虫草生境中的海拔、坡向、土壤、温湿度、植被、寄主食物等方面调查了兰坪虫草的生态学特性,结果表明:兰坪虫草主要分布于横断山区海拔2 600~3 400 m的高山草丛,通常呈片状分布;生境中土壤主要为棕壤或黑褐土,土质较疏松、微酸性,含水量适中;寄主云南蝠蛾的食物多样,主要以草本植物如艾蒿、西南鸢尾、血满草、龙牙草、大理蓟等的幼嫩根茎为食,偶以枯枝落叶层的腐殖质为食;生境中分布的昆虫及病原菌是调节兰坪虫草寄主蝠蛾生态平衡的重要生物因子。本研究结果将为兰坪虫草的仿生态栽培及其资源保护提供参考。

摘 要：
Ophiocordycep lanpingensis H Yu & ZH Chen is a newly found closely related species of Ophiocordycep sinensis(Berk.) G.H.Sung,J.M.Sung,Hywel-Jones & Spatafora and has high medicinal value.It is necessary to strengthen the protective research of O.lanpingensis because its wild resource is decreasing.We investigated the ecological characteristics of O.lanpingensis from the aspects of elevation,exposure,soil,humiture,vegetation,and food of the host.The results showed that O.lanpingensis mainly distribute in mountain-grasses of 2 600 ~ 3 400 m elevation over Hengduan Mountains Region,usually patchy in distribution.The soil is mainly brown or black brown,loose,mild acid,with lower water content.The foods of Hepialus yunnanensis Yang,Li & Shen were diverse,mainly relied on green rootstock of herbaceous plantssuch as Artemisia argyi Levl.& Vant.,Iris bulleyana Dykes.f bullegana,Sambucus adnata Wall.,Fragaria nilgerrensis Schlecht.& Gay.,Cirsium taliense(Jeffrey) Lévl.,and occasionally on humus of litter layer.The insects and pathogenic microbes in the habits might be the factors to regulate the ecological balance of Hepialus larva.The study would provide reference for the simulation-forestry ecology cultivation and the resources protection of O.lanpingensis.
