中甸刺玫是云南香格里拉特有的极危植物和著名的高山花卉。通过对其分布及种群现状进行全面系统的调查,绘制了中甸刺玫的地理分布图及基于株高和冠幅的年龄结构图,编制了相应的种群静态生命表并绘制了相应的存活曲线。结果表明,除人工引种保存的69株个体外,中甸刺玫自然分布在香格里拉县小中甸镇沿硕多岗河的狭长型地带内,现有自然分布点44个,植株562株,其中幼苗61株。大多数分布地点仅有1至几株成年植株,几乎没有更新。个体数多的分布点中植株的表型变异较大,花型、瓣性和花色等丰富。中甸刺玫Ⅱ龄级至Ⅴ龄级的个体数较多,幼苗和老年个体较少,种群年龄结构在一段时间内比较稳定,但长远来说处于衰退状态。中甸刺玫的死亡率随着龄级的增加而增加,株高结构中存活数在Ⅱ龄级最高,冠幅结构中存活数则在Ⅲ龄级最高,随着龄级的增加存活数降低。
Zhongdian Rose is a rare and endemic Yunnan Shangri-La plants and famous mountain flowers. Through a comprehensive and systematic survey of its distribution and population status, the geographical distribution map of Zhongdian spiny rose and the age structure map based on plant height and crown width were drawn, and the corresponding static life table of the population was compiled and the corresponding survival curves were drawn . The results showed that in addition to the artificial introduction and preservation of 69 individuals, the natural distribution of Pinaceae in Zhongdian Xiaolandian Town, Shangri-La County, along the long strip of Shuodoganghe, has 44 natural distribution points and 562 plants, of which 61 seedlings. Most of the distribution sites are only 1 to a few strains of adult plants, with almost no update. The phenotypic variation of plants in the distribution of individual number is large, the flower pattern, petal and flower color are rich. Zhongdian sparse rose II to Ⅴ age class number of individuals more seedlings and elderly individuals less population age structure in a period of time more stable, but in the long run in recession. The mortality of Zhongmei rosewood increased with the increase of age grade. The survival rate of plant height structure was the highest in age group Ⅱ, while the survival rate in crown structure was the highest in age class Ⅲ, and the survival number decreased with age .
