摘要: 以长白松(Pinus sylvestriformis)种群为例,通过种群发展历史、种群大小结构研究,发现种群的胸径服从正态分布N(16.87,6.802),确认该种群为自然同龄种群.种群的空间分布格局呈很高的均匀性,趋于随机分布甚至均匀分布,分布格局动态表现出由均匀分布向随机分布变化的趋势.

Abstract: Studies on the history and size structure of Pinus sylvestriformis population show that the DBH of the population is submitted to normal distribution (N 16.87, 6.082), being natural population with same age. Its spatial pattern has a higher evenness, and tends to a random or even distribution. The dynamics of distribution pattern shows a transformation from random to even distribution.

Key words: Pinus sylvestriformis, Natural population with same age, Spatial distribution pattern, Random distribution, Even distribution, species biodiversity, canopy coverage, evergreen broadleaved forest, canopy vertical structure
