摘    要:应用生命表和生存曲线对缙云山斑苦竹无性系种群的数量进行统计分析,结果表明,①斑苦竹竹笋-幼竹无性系种群的生存曲线介于B型与C型之间,是一条较为平缓的凹形曲线,其死亡率为40%,②斑苦竹无性系种群的年龄结构比较稳定,但已表现出轻度的衰退迹象。③生存曲线呈波状曲折的C型,各龄级竹子构件的死亡率不同,幼龄和老龄竹死亡率较中龄竹子大.

关 键 词:斑苦竹;无性系种群;生命表;生存曲线;年龄结构

Abstract:his paper deals with the demogarphy of Pleioblastus maculata clone population in Jinyun Mountain by the methods of life table and survivorship curve.The results show :1. The survivorship curve of bamboo shoot-young bamboo clone population for P. maculata is be-tween B-type and C-type , it is a gentle concave curve. This clone populations mortality, rate is 40%.2. Age-class strucrure of bamboo modules for P. maculata is stabler , but it appears slight decline. 3. The mortality rate of bamboo modules of differnent age-class for P. maculata is various. Themortality rate of young and old bamboo modules is higher than medium bamboo. The survivorship-curve of this clone population appears C-type and wavey curve.
Keywords:Pleioblastus maculata  clone population  life table  survivorship curve  age-class structure
