| 摘 要： | 沙地云彬是我国内蒙东部沙地森林草原过渡带的特有濒危树种，沙地杉林是陆地上非常特殊的森林生态系统类型。本文研究了沙地云杉的种群动态，建立了沙地云杉种群生命表、年龄结构、存活曲线和生殖力表，同时研究了沙地云杉种群分布格局及增长动态，可为沙地治理和沙地森林生态系统研究提供科学依据。

| Abstract: | Picea mongolica is an endemic and endangered tree species in sandy forest steppe ecotone in eastern Inner Mongolia Autonomous Region of China, and P. mongolica forest is a very special sandy forest ecosystem. In this paper, population dynamics of P. mongolica in sandy forest steppe ecotone were studied; the population life table, age structure, survival curve, and fecundity schedule were established; and population distribution pattern and increasing tendency were also studied to provide some scientific bases for sand controlling and researches on sandy forest ecosystems.
