报道了砍伐和焚烧农业(Ohum)后的演替植物群落。(2)1年生、3年生、5年生、10年生和20年生休闲林的个体更新和死亡格局表明，老休闲区的苗木种群比新生休闲区的苗木种群死亡更严重。10岁和20岁的Flowers没有招募人员。在5年生的休耕中，成年枝条的死亡率最高。(3)根据生态条件的变化，讨论了种群数量和繁殖产量的变化，并讨论了这些结果与JHUM循环的关系。
successional plant communities following slash and burn agriculture (Ohum) are reported. (2) The recruitment and mortality patterns of individuals in 1-, 3-, 5-, 10- and 20-yr-old fallows showed that the seedling population experienced more severe mortality in older fallows than in newer fallows. No recruitment occurred in 10- and 20-yr-old fallows. The mortality of adult shoots was greatest in a 5-yr-old fallow. (3) The changes in population size and reproductive output are discussed in the light of changing ecological conditions and the implications of the results are discussed in relation to the jhum cycle.
