滇西北云南红豆杉种群空间分布格局
Spatial Distribution Pattern of Taxus yunnanensis Population in Northwest Yunnan Province
摘要
Abstract
Taxus yunnanensis is an endangered species distributed mainly in southwestern China. Based on the distribution characteristics of T. yunnanensis population, 9 sampling plots, each with an area of 400 m2 were established in the concentrated distribution area in northwest Yunnan to investigate the spatial distribution pattern and dynamics by using discrete distribution theory. The results showed that most of individuals concentrated in size class HI and IV , and few or none individuals appeared in size class I and Ⅱ indicating that the regeneration of T. yunnanensis was difficult. At different sampling areas, such as 5 mX 5 m, 5 mXlO m and 10 mXlO m, T. yunnanensis populations all performed the pattern of congregation distribution. T. yunnanensis populations also performed the pattern of congregation distribution at different age stages, indicating that congregation distribution was the basic attribute of spatial distribution of T. yunnanensis population in northwest Yunnan.关键词
