During the study, researchers recorded the width of the tree rings of balsam firs. Each ring marked a year of the tree's growth. A narrow ring indicated that the tree's growth had been suppressed that year.

在此研究中，研究者们记录了胶冷杉的年轮和宽度，一圈年轮代表胶冷杉成长了一年，某一圈较为细密的年轮代表在这一年内胶冷杉的成长受到了压制。

During the study, researchers recorded the width of the tree rings of balsam firs. Each ring marked a year of the tree's growth. A narrow ring indicated that the tree's growth had been suppressed that year. The narrow rings appeared only after wolf populations decreased, allowing a greater number of moose to survive and eat more balsam firs.

研究期间，研究人员记录了香脂冷杉树轮的密度，一个树轮表示树生长了一年，有一圈年轮显示出树木在那一年的生长受到了阻碍，根据树的年轮推断出现阻碍的这一年，正是狼群数量减少，鹿的数量大量繁殖的那一年，鹿比平常吃了更多香脂冷杉。

At all the shrub layer and herb layer plants, both widely distributed in the cloud belt elevation fir forest types, there is also limited to certain types of spruce-fir forest types.

在所有灌木层和草本层植物中，既有广泛分布于各海拔带云冷杉林中的种类，也有仅限于某一云冷杉林类型中的种类。

Major results were summarized as follows:(1) A total of 58 tree species from 53 genera in 36 families among which 8 species were Rosaceae, 5 species were Liliaceae, 5 species were Eriaceae, 3 species were Ranunculaceae, 3 species were Compositae, 2 species were Cupressaceae, 2 species were Caprifoliaceae, 2 species were Umblliferae, and other 28 tree species were only one receptively. These were recorded in the 8 plots of the A. georgei var. smithii forest;(2) Number of families, genera, species and Margalef index correlated negatively with altitude (P.05), with a peak at 3600 m.(3) Shannon-Wiener index correlated negatively with altitude (P.01), and maintained stable at the altitudes between 3700~4100 m, evenness with altitudes, however, this trend was insignificant.(4) Jaccard index increased sharply with increasing altitude at the altitudes between 3600~4100 m, and was lower between different vegetation types at the altitudes between 4100~4200. Cody index β(subscript c decreased with an increasing altitude, but there were 2 troughs between 4000~4100 m and 4200~4300 m.(5) Maximum tree height H(subscript max and HH(subscript max=37 mcorrelated negatively with altitude (P.05); but basal area and BA BA(subscript max=5.3m^2 correlated with altitudes, however, this trend was insignificant.

结果表明：(1)在调查的8个急尖长苞冷杉林样地内共有植物58种，分属于36科53属，其中植物较多的科有蔷薇科8种、百合科5种、杜鹃花科5种、毛茛科3种、菊科3种、柏科2种、忍冬科2种、伞形科2种，其余的28科各只有1个种；(2)物种科、属、种数、Margalef指数D(下标 M与海拔存在显著的负相关性(P.05)，在分布急尖长苞冷杉最低海拔3600m处出现物种丰富度的最大值；(3)多样性指数与海拔之间有极显著的负相关性(P.01)，并且在3700~4100m之间多样性指数保持稳定；均匀度指数与海拔梯度之间存在负相关性，但不显著；(4)Jaccard指数C(下标 j在海拔3600~4100m随海拔的升高而升高，在生境过渡带的4100~4200m之间Jaccard指数C(下标 j较低；Cody指数β(下标 c随海拔的升高呈下降的趋势，但在4000~4100m和4200~4300m 海拔区间出现2个低谷；(5)最大树高H(下标 max和最大胸径DBH(下标 max与海拔之间存在显著负相关性(P.05)；胸高断面积之和和立木密度与海拔之间存在负相关性，但不显著。

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）。

In addition, the authors suggest:① The research of firs hybridization should be carried out on a large scale in China;② In hybridization, the phylogeny of Abies must be considered, and we should put emphasis on the intro-section hybridization;③ The research on the strobili phenology of firs can ensure the hybridization succeed;④ The research is also important for the hybridization to study the genetic diversity of Abies;⑤ We can use the biotechnology and the knowledge of modern molecular biology to overcome the difficulties of breeding.

作者对我国开展这项研究提出了几点看法：①应大力开展我国冷杉树种间，以及与国外冷杉树种间的杂交研究；②杂交时必须考虑种的系统关系学并以派内杂交为主导方向；③对我国冷杉属树种进行开花结实习性研究；④开展我国冷杉属树种的系统学和遗传多样性研究；⑤结合现代生物技术和分子生物学知识，克服常规杂交中的困难。
