| 摘 要： | 根据安曹下杉木丰产林全林林窗样地调查资料,分析了杉木林林窗的大小结构、形成方式及林窗形成木的数量特征。结果表明,在安曹下杉木林中,林窗的面积为22.75-319.92 m2,平均面积为102.3 m2,林窗大小多为50-200 m2,其中以50-100 m2所占的数量比例最大,且所占的面积比例也最大;林窗形成方式由砍伐形成的最为普遍,占形成木总数的70.45%,其次是由于枯立而形成的,占22.73%;林窗大多由1株形成木形成,平均每个林窗拥有形成木1.33株。

| Abstract: | Based on the data of gaps in Cunninghamia lanceolata forest in Ancaoxia,China,the size and formation pattern of gaps as well as the quantitative characteristics of gap makers were studied.The results showed that the size of all gaps varied from 22.75 to 319.92 m2 and had an average area of 102.3 m2;most gaps ranged from 50 to 200 m2 in size;the gaps of 50-100 m2 took up the largest percentage in number and area.The most common gap formation in the forest was felling(70.45% of the total of gap makers),with standing dead trees(22.73% of the total) coming in second. Most gaps were formed by a single maker,and a gap contained 1.33 gap makers on average. |
