对西双版纳勐仑地区的热带雨林刀耕火种撩荒后在不同抚育方式下恢复起来的次生植被进行了群落数量特征、种群年龄结构及立木材积与蓄积量的比较分析，并探讨了热带次生植被的抚育管理方式及途径．结果表明，在９００ｍ２的固定样地上，天然更新的次生群落计有维管束植物７３种，分属于３６科５９属．其科、属、种组成比经人工抚育的次生群落分别高２４．１４％、４３．９０％和７５．５６％，其结构层次也较复杂，但材积量仅为后者的１／４．
The characteristics of community quantity, population age structure and stand volume and stock volume of secondary vegetation restored by different tending ways after slash-and-burn of tropical rain forest in Menglun district of Xishuangbanna in Xishuangbanna were studied. The effects of tropical secondary vegetation Tending management methods and ways. The results showed that there were 73 species of vascular plants in the newly regenerated secondary community, belonging to 36 families and 59 genera. Its families, genera and species composition are 24.14%, 43.90% and 75.56% higher than that of artificial secondary families, respectively. Its structure level is also complicated, but its volume is only 1/4 .
