不同坡向濒危植物南方铁杉的分布格局

Spatial Distribution Pattern of the Endangered Plant Tsuga chekiangensis in Different Aspect

以福建省武夷山国家级自然保护区内南方铁杉群落调查资料为基础,应用C、CI、Iδ、M*、PAI、Ca等聚集度指标测定方法研究濒危植物南方铁杉的空间分布格局,结果表明,南方铁杉的空间分布呈随机分布,但不同坡向南方铁杉分布格局的成因不同。

Based on the investigation of the Tsuga chekiangensis plantations in the Wuyishan National Nature Reserve, the concentration class index, C, CI, I8, M＊, PAI and Ca were used to research spatial distribution pattern of the Tsuga chekiangensis plantations in different aspect. The results showed that the spatial distribution pattern of Tsuga chekiangensis Flous was random pattern in population, but the courses of distribution pattern were different in different aspect.
