摘要
通过静态生命表分析赤松 (PinusdensifloraSieb .etZucc .)种群的生命结构与数量动态。结果表明 ,赤松种群具有不同年龄等级结构 ,死亡高峰出现在 5～ 15年 ,此时正是幼龄期向成年期的过渡阶段 ,度过此阶段的赤松个体大多能达到生理寿命。由此看出 ,赤松种群静态生命表能较精确地反映赤松种群的数量动态规律。
By using the static life table, the life structure and quantitative dynamics of \%Pinus densiflora \%Sieb. et Zucc. population in Shandong Province were analysed. The results indicated that \%P. densiflora\% population has different age\|grade structure, and that mortality summit of the species population appears during the time from age 5 to age 15——from its young period through grown\|up period, and the individuals pulling through this period can almost attain their physiological life\|span. So the static life table can reflect accurately the regularity of the quantitative dynamics of \%Pinus densiflora\% population.
