| 摘 要： | 林隙特征(gap characteristics)是研究林隙的作用、影响以及动态变化规律的基础。研究工作以燕山山地新丰林场油松人工林为研究对象,采用样带法进行野外调查,分析了林隙的形成方式、形状、大小、年龄结构、边缘木等特征。结果表明:人工近熟油松林林隙的形成主要为抚育间伐和择伐等人为因素形成,自然形成的较为罕见;形状为近椭圆形,且林隙的形状与面积并无相关性;林隙的面积多集中在40～60m~2,所占数量比例和面积比例均为最大,分别为33.33%和22.22%;以高度为14～16m的林隙居多,略低于林分的平均高;发育后期的林隙及前期的林隙居多,分别占到林隙总数的40.00%和31.11%。

| Abstract: | Cap characteristics is the basic of researches on gap's functions,effects and dynamics.In this paper,we completed field work by transect sampling method in Pinus tabulaeformis plantantion of XinFeng forestry centre in Yanshan Mountain,and analysed forming - manner,sharp,size,age structure,border tree of gap.The results showd that the main reasons of gaps formation of near - mature - P.tabulaeformis plantantion were thinning,selective cutting,and other artificial factor,whereas the way of gaps formation by n... |
