摘要:
 在青海省三江源自然保护区麦秀林区，对青海云杉（Picea crassifolia）种群进行垂直样带调查，分析了不同发育阶段和不同海拔高度青海云杉空间格局及其影响因素。结果表明：1）青海云杉种群幼苗、幼树阶段个体数量仅占总体数量的6.6%左右，远低于其他3个发育阶段，已处于衰退的早期阶段；2）不同发育阶段的青海云杉种群均呈集群分布，除幼苗、幼树外，随径阶的增大或年龄的增加，种群呈扩散趋势；3）分布于不同海拔的青海云杉种群均趋于集群分布，但其聚集程度不尽相同。
Abstract:
 A vertical transect investigation on Picea crassifolia forests was conducted in Maixiu Forest Farm of Sanjiangyuan Nature Reserve, Qinghai Province, China. The objectives were to analyze the spruce population structure type, the characteristics of the population’s spatial distribution pattern and their factors in different habitats. The results showed that the amount of seedlings/saplings, accounting for only about 6.6% of the total，were far lower than that of the other three demographic stages (small trees，middle trees，and big trees). The population structure diagram had already been in the early stages of a recession. P. crassifolia population in different development stages showed clumped, except for seedlings/saplings, there was a spread trend with the increase of DBH and age. The spruce populations in different altitudes presented a clumped distribution, but clustering intensity had different values.
