| 摘 要： | 报道和分析了峨嵋山冷杉森林的衰退状况。对冷杉种群的受害程度、分布规律、症状特点及其与海拔、特定生境、立木径级和林型的关系进行了研究分析。指出峨嵋山冷杉森林衰退是全球森林衰退的组成部份，而不是个别的或偶然的现象；肯定了当地冷杉林衰退具有某些个性特征。由此认为，导致当地冷杉衰退的主要原因可能是某种或某些作用范围广、持续时间长、发生频率高、对全球森林系统构成威胁的因素所致。

| Abstract: | This paper reports and analyses the decline state of the Abies fabri forest in Mountain Emei. The damage degree, distribution and symptom features of the fir populatiori are studied and the relationship of these above with altitude,special habitats, the breast height diameter of the fir trees and forest types is discussed. It is pointed that the fir forest decline in the mountain is not one or two and chance phenomenon,but the part of the forest decline in the world after studying some achivement from Europe and America.Sometimes the paper also agrees there are some special features of the decline there. The essential or major cause to lend the fir decline may be some causes, such as threatenning the system of forest in the world,acting in wide range and long time,and happenning in high frequency. |
