Turkish population of 241,198, mainly in Qinghai, Gansu (30), Daur population of 132,394, mainly in Inner Mongolia, Heilongjiang.

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）。

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 population density was different at various altitudes, and among them, the biggest one was the population C. The life tables showed that the death rates at age class Ⅱ,Ⅲ,Ⅳ were higher, so the death rates decreased with the diameters class increasing, after age class Ⅳ or Ⅴ, however, the death rates increased again. The expected life was longer before class Ⅳ, and decreased gradually with the age increasing. The survival curves of different populations was close to Deevey Ⅲ type. The dynamics of C.

不同海拔的种群密度存在差异，其中C种群密度最大；静态生命表显示，种群在Ⅰ、Ⅱ径级时死亡率较高，随着年龄增加，死亡率逐渐降低，但到了Ⅳ、Ⅴ径级，由于生理衰老死亡率又上升；种群期望寿命在Ⅱ、Ⅲ、Ⅳ径级较高，随着年龄增加，期望寿命逐渐下降；不同海拔的米槠种群的存活曲线均接近于Deevey Ⅲ型。

As a result, the P schrenkiana population has reverse-J shaped DBH class, age structure and tree density patterns but with a bell-shape biomass pattern. The Schrenk spruce population also has a classical linear survivorship curves between Deevey Ⅱ and Deevey Ⅲ type.

研究结果表明中部天山雪岭云杉种群的胸径、年龄结构和种群密度都呈倒－J型分布，种群生物量呈钟型分布，存活曲线基本介于Deevey Ⅱ和 Deevey Ⅲ型之间。

The result shows that the Giant Panda habitat in Gansu is an under-plant population of forest communities with Fargesia denudate as the dominant species; that Giant Panda make movements at the altitudes ranging from 1 600 m to 2 000 m in Wenxian County and Diebu County; that the characteristics of bamboo population, geographical environment, along with the integrity of forest communities, are taken as the three dominant factors in influencing the life of Giant Panda;and that the features of the habitat are basically stable but reasonable distribution together with strong artificial disturbance is considered as the potential factor resulting in the habitat unstable.

结果表明：甘肃省大熊猫主要栖息在以缺苞箭竹为优势的下木种群森林群落中，其垂直活动范围主要集中在海拔1 600～2 800 m处，水平分布在文县和迭部一带；竹类种群的特性、地理环境和森林群落的完整性是大熊猫栖息生存的3个主要综合要素；甘肃省大熊猫的生境特征基本稳定，但该区竹类种群的正态性分布和人为干扰强度是构成其生境不稳定的重要潜在因素。
