摘 要 ：自然稀疏是林分内的个体由于竞争有限的资源而引起的一部分个体死亡的现象。评述 4 0 a来世界上有关纯林自然稀疏的研究内容 ,包括了自然稀疏法则 ,异速生长模型、平均个体重与密度的时间轨线 ,种的自然稀疏线和自然稀疏动力线的关系 ,自然稀疏线的斜率与生物量的关系 ,自然稀疏与竞争密度效果的关系 ,自然稀疏的机理。

Abstract:Self thinning is a phenomenon of the mortality of some individuals caused by intraspecific competition. The researches on self thinning pure stands for 40 years in the world were summarized and evaluated including self thinning rule, allometric model, mean individual weight density trajectory during the course of self thinning, species self thinning line and dynamic thinning line, the relationship between the slope of self thinning line and biomass, the relationship between the self thinning and co...
