摘　　要：2007年4月通过对云南省德宏州陇川县内40块样地的调查,分析了中缅木莲的年龄结构、高度结构、空间分布格局,编制了特定时间生命表,绘制了存活曲线。结果表明:中缅木莲成年个体数较多,幼年植物个体较少,居群属衰退型居群;个体高度发育,较为连续;其空间分布格局表现为随机分布;从幼苗生长到树木死亡分4个阶段,其幼树、成树阶段死亡率较低,幼苗、老树阶段死亡率较高。We surveyed 40 transects in April 2007,to analyze the age structure,tree height,spatial pattern of Manglietia hookeri tree in plots of Longchuan County of Dehong Prefecture.Its life table and survival rate curve were made in accordance with the results.It showed that the population had more individuals of adult trees but less in saplings,which appeared as declining tendency;the individuals of same size class appeared evenly in height and continuous.Its spatial pattern was stochastic in the plots.It could be divided into 4 stages in the population from seedling to adult.Among them,the mortality in seedlings and adults were low but high in saplings and senile trees.
