摘　　要：应用生命表和生存分析理论,编制了篌竹竹笋-幼竹无性系种群的动态生命表,篌竹无性系种群的静态生命表,并绘制了存活曲线、死亡曲线和死亡率曲线。结果表明:(1)篌竹竹笋-幼竹无性系种群的存活曲线趋向于DeeveyⅡ型,死亡率高达68%,死亡曲线有两个高峰,分株死亡主要集中在前期,主要原因是母竹营养供应不足。(2)篌竹无性系种群的存活曲线也趋向于DeeveyⅡ型,平均期望寿命随年龄增加而下降。The paper worked out a dynamic life table of bamboo shoot-young clone population of PhyUostachys nidularia Munro, a static life table of Phyllostachys nidularia Munro, drew the curves of survival, mortality, mortality rate. The results showed that： （1） The surviving curve of bamboo shoot-young clone population of Phyllostachys nidularia Munro tended to the type of Deevey Ⅱ . The mortality rate of bamboo shoot was 68 %. The mortality curve had two climaxes.The death of rameat was mainly at the preliminary stage. The main reason of death was the scare of nutrition. （2） The survivorship curve of Phyllostachys nidularia Munro clone population also tended to the type of Deevey Ⅱ . The expect life-span decreased with the age increase.
