摘要: 比较了国内外已有的乔木郁闭度测量方法的优缺点,在样点法特别是观测管法的基础上,以北京延庆地区乔木林为对象,对郁闭度的激光测量进行了研究。实验改进了观察管法,对在野外测量乔木林郁闭度时精确测量所需样点数进行了研究,可以为野外快速、简洁、精确地测量乔木林郁闭度提供新的方法与参考。

关键词: 郁闭度, 激光测量, 样点数

Abstract: The survey of forest canopy density is an important factor of forest survey.There have been some forest canopy density measurement methods at home and abroad,but all more or less have defects.Based on the point methods and the observation tube method in particular the laser measurement of tree canopy density was deeply studied.The Experiment not only improved observation tube method,but also solved the required number of points for a kind of precise measurement,which is still a controversial issue at home and abroad.This provides a new method and reference for finding a fast,simple and accurate measurement of forest canopy density

Key words: canopy density, laser measurement, the point method
