【摘要】 三江平原低山丘陵区水曲柳无性更新—伐根萌芽更新进行了初步研究 ,以不同径、高的伐根所产生萌生枝数量、基径与高度为指标 ,探讨了该更新方式的规律与动态 ,得出由伐根萌芽所产生的萌枝数量与伐根径的变化呈多项式分布关系 ,与伐根高的增大呈对数分布关系 ,且对水曲柳萌生枝的动态做了初步分析得出其萌生枝可代替主干形成高大树木。更多还原

【Abstract】 Stump sprout play an important role in the restoration of second ary for est. In the study, ma1inly discussed the relation between the height and diamete r of stump and the number (including the total, dead and living) and height of s tump sprout as well as the dynamic of stump sprout regeneration. Discovered the number of stump sprout present multinomial pattern as increase of the stump diam eter and do logarithmic pattern as the increase of stump height, moreover, disco vered the stump sprout can develop to be big tree in stead of the trunk fallen b y investigation and analysis of stump sprout dynamic.更多还原
