青海杂多县冬虫夏草的生态调查

对青海省杂多县冬虫夏草及其寄主的自然生境进行调查研究发现,该县虫草主要分布于海拔4 000～4700m的高寒草甸或高寒灌丛中。因海拔、植被、地形和水热条件的不同,虫草及其寄主具有明显的垂直地带性分布特征。在青藏高原长期的进化过程中,虫草寄主形成耐寒、耐涝、耐饥的生态习性。水、热、光是完成虫草有性世代的主要因子。

Ecological Investigation of Cordycepes sinensis in Zaduo of Qinghai Province

In this paper the natural environment of Cordycepes sinensis and its host insect in Zaduo of Qinghai was studied.The results showed that Cordycepes sinensis was mainly distributed in alpine-cold meadow and alpine-cold bush with altitude 4 000 m to 4 700 m.It was characterized by a clearly upright-distributing due to the different altitude,vegetation,landform and atmospheric temperature,humidity.Its host formed the ecological habit of enduring cold,flood and hunger in Qinghai-Tibetan platean.Water,heat and daylight were the main genes that the sexual generation was completed.
