The results showed that: 1 The survival curve of the population conformed to the type of Deevey-Ⅲ; 2 With an increase in the population mortality ratio and a decrease in the survival rate, the mortality ratio greatly increased in ages 0-40 years, reaching 89.7%; 3 There existed two peaks of mortality in the lifespan, one was from seedlings to young trees (0-40 years) and the other in the adult stage (180 years).

结果表明：1岷江上游林线地段岷江冷杉种群存活曲线趋於Deevey-Ⅲ型。2林线地段岷江冷杉种群生存率呈单调下降趋势，生存率下降趋势前期高於后期，说明岷江冷杉种群幼苗死亡率高，种群后期比较稳定。3林线地段岷江冷杉林整个生长期中出现了两个死亡高峰期，一个出现在幼苗向幼树过渡时期（0~40年），另一个出现在中龄时期（180年）。

On the basis of census of all individuals of the populations at different plots, the structure and dynamics of the populations were described. The result showed that P. tabulaeformisf.shekannesis were growing populations, and the distributions of the structure were reverse J. The density decreased with the increasing of Size-class structure. The populations developed the characteristic of increasing in the early stage and stabilizing in the late. The survive curve of Pinus tabulaeformisf.shekannesis were between DeeveyⅡand DeeveyⅢ. The analysis of time sequence showed that most of the inividuals would be adult after 20 years.

结果表明：柴松种群结构呈反J分布型，种群处于增长阶段；种群的密度随径级的增加而降低，种群密度与径级呈现出明显的负相关；四个函数估计值说明柴松种群具有前期增长、后期稳定的特点，其存活曲线介于DeeveyⅡ型和DeeveyⅢ型之间；随时间推移，种群中树和大树数量逐渐增多，种群在20年后开始大量进入成熟阶段。

The survival curve of the population was between Deevey Ⅱ and Deevey Ⅲ with two peaks of mortality rate. Four functions (survival rate, mortality rate, mortality density function, hazard rate) all indicated that the population increased at the early stage and kept stable at the late stage.

其存活曲线介于Deevey-Ⅱ型和Deevey-Ⅲ型之间，呈现2个死亡高峰。4个生存函数值（生存率、积累死亡率、死亡密度、危险率）均说明该种群具有前期增长、后期稳定的特点。

The results showed that the number of young individuals was larger than that of middle aged and old individuals in the B. platyphylla population. The population had one peak of mortality in size class Ⅴ. The survival curve of the population appeared to be the Deevey-Ⅱ type. The population was a rise type at present.

结果表明：白桦种群幼年个体丰富，中老年个体相对较少，种群在第V龄级出现死亡高峰，种群存活曲线属于Deevey-Ⅱ型，白桦种群目前表现为增长型种群。

The impacts on the diameter levels V and VI were indicated as abnormal increase of survivorship, negative values of mortality and decrease of mean life expectance whereas the impacts on the diameter levels III and IV were opposite to the levels V and VI. The survivorship curve of the Quercus variabilis population was fit with Deevey II.
