【摘要】 本文探讨了火烧迹地上红松种群(Pinus koraiensis population)自然更新格局的动态变化和趋势.从传统的2×2(m~2)更新样方的系统抽样资料统计分析中,清晰地显示出,更新格局随着时间的推移发生着规律性的变化.处在进展演替状态的新生群落,当红松种群在群落中自然更新发生时,其格局将由群团型格局向随机型格局发展,过程可能十分复杂,主要决定于种群的生物学特性和生态环境的相互作用.更多还原

【Abstract】 The present paper studies the dynamic change and tendency of natural regeneration pattern of Korean pine ( Pinus Koraiensis) population . From the statistic analysis of the systematic sampling data according to the traditional 2×2 ( m1 ) regeneration patter n , it is obviously shown that the regeneration pattern undergoes regular changes with the advance of time.As a new-born community in a state of evolution , when the natural regeneration of a Korean pine pupulation takes place, its pattern tends to change from the aggregate type to the random type . The process may be very complicated , mainly depending on the interaction between the population’s biological traits and the ecological environment.更多还原
