摘要
林隙面积分布格局是林隙的一个重要特征。林隙的大小不同 ,直接影响着林隙内的生态环境 ,进而对树种生长与更新产生不同的作用。通过对万木林中亚热带常绿阔叶林 96个林隙面积的调查 ,研究其冠空隙和扩展林隙面积的分布特征 ,用韦布尔 (Weibull)分布模型拟合冠空隙和扩展林隙的面积分布格局。结果表明 :中亚热带常绿阔叶林林隙冠空隙和扩展林隙面积分布格局均符合Weibull分布。
The distribution pattern of gap area is an important characteristic of gap. The size of gaps directly affects the ecological environment of gap, and has an significant effect on the growth and regeneration of the trees. Through field investigation of 96 gaps in the mid-subtropical evergreen broad-leaved forest in Wanmulin Natural Reserve of Fujian Province, the characteristics of canopy gap areas and expanded gap areas were studied, and the distribution of the areas of gaps were simulated with Weibull model. The results showed that both canopy gap area and expanded gap area all followed Weibull model.
