| 摘 要： | 对卧龙自然保护区各林分中的145个林隙进行调查,并对林隙特征进行研究,结果表明:卧龙自然保护区林分中林冠空隙的大小变化范围为5.4～298.3 m2,平均为47.75 m2,扩展林隙的大小变化范围为21.6～379.4 m2,平均为218.1 m2;林隙形成的主要原因是倒木、人为砍伐及折干;林隙形成木从1～6株不等,每个林隙以2～3株形成木最多,平均每个林隙的形成木有2.6株;林隙形成时间以0～20 a时间为主,其中在5～15 a期间形成的林隙最多。

| Abstract: | An investigation into the 145 forest gaps in Wolong Nature Reserve was conducted,and the gap characteristics were re-searched.The results showed that the change range of forest canopy gap was 5.4~298.3 m2,the average was 47.75 m2;the change range of expand forest gap was 21.6~379.4 m2,the average was 218.1 m2;the main causes of forest gap formation were fallen wood,human cutting,trunk snapping;the number of gap maker was between 1 and 6,the biggest number in each forest gap was 3 and the average was 2.6;the... |
