摘　　要：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．Two secondary vegetations regenerated from the tropical rain forest in Menglun, Xishuangbanna after its. slash and burn cultivation were comparatively analyzed on their quantitative characteristics of community, population age structure, standing tree volume and stand volume. The results show that in a 900m 2 fixed plot, the natura secondary community had 73 species, 59 genera and 36 families of vascular plants. and the numbers of family, genus and species in it were 24.14%, 43.9% and 75.56% respectively higher than those of secondary community with artificial tending. The structure of the natural secondary community was also more complex than that of the artificial one, while the stand volume of the former was only 1/4 as much as that of the latter.
