摘要: 本文用种群大小结构代替年龄结构研究了沙地云杉种群的大小结构、分布格局和动态规律.结果表明,样地1、2、3、5的沙地云杉种群属于增长型,样地4的沙地云杉种群为稳定型,将样地1、2、3作为一块样地,其分布格局为集群型,但从幼树到大树,则由集群分布变为随机分布.

Abstract: The size structure and distribution pattern of Picea mongolica population on sand dune and their rerlationship to eco-environment are studied by size structure in place of age structure. The results show that the population is charactrerized by increasing type in plots 1,2,3 and 5, and static type in plot 4. Regarding plots 1,2 and 3 as a plot, the population distribution pattern in contagious, which becomes random when young trees are getting matured.

Key words: Picea mongolica, Size structure, Distribution pattern, Population dynamics
