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)
