【摘要】 本文对三种不同群落中的刺五加种群编制了生命表,并根据致死力k_X、的动态变化趋势分析了环境阻力与种群动态的关系。环境与种群的相互作用大致分为六个阶段。种群的存活曲线属DeeveyⅢ型。更多还原

【Abstract】 The life tables of A.senticosus population in three different communities have been.made.The relationship between environmental Pressure and population dynamics has been analysed according to the dynamic variation trend of kx(killing power).The interactions between environment and population can be approximatly divided into six phases.The survivorship curve of the population belongs to the Deevey Ⅲ type.更多还原
