摘要

以内蒙古大兴安岭南段次生林区为研究对象,采用LAI-2200冠层分析仪对林分叶面积指数(LAI)进行了监测。结果表明:除林型Ⅰ外LAI的最大值均出现在5月份且在坡顶,最小值出现在8月且在中上坡位;纯林的LAI值均高于相同月份混交林。6—8月的LAI值与胸径和树高均呈负相关,而各月份的林分密度与LAI值均呈正相关。

Abstract

The research object was secondary forests in southern Daxinganling.Canopy analyzer of LAI-2200 was used to monitor leaf area index(LAI),the results show that the maximum value of LAI occurred in May and was always shown at the top of slope except forest typeⅠ,the minimum value of LAI appeared in August and the middle-top of slope.Besides LAI value of pure forests is higher than mixed forests.The LAI value of June,July and August is negatively related with DBH and tree height,however the LAI value of each month was positively related with forest stand density.

Key words： Daxinganling; secondary forests; leaf area index(LAI)
