Epiphytes in man-made forests simulating a mixed tropical forest of South Vietnam are studied. With respect to the number of species, epiphytic orchids are better represented than ferns (six vs. five species); on the other hand, the latter prevail in the number of individuals. A comparison of the floristic composition of the epiphytic community of plantations with a nearby primary forest (Stugrun–Rădulescu index ρsr = 0.68) and two other South Vietnam forests (Ma Da Forestry and Phu Quoc Island; ρsr = 0.61 and 0.71, respectively) did not reveal significant similarities. However, these data indicate that a relatively complex epiphytic community, which can accumulate up to 100 kg/ha of deposited organic matter and plant mineral nutrients in crowns, has been formed in the man-made forests over 20 years.

南越人工林附生群落的形成

研究了模拟南越热带混合森林的人造森林中的附生植物。就物种数量而言，附生兰花比蕨类植物更具代表性（六个对五个物种）；另一方面，后者在人数上占优势。人工林附生群落与附近原始森林（Stugrun-Rădulescu 指数 ρsr = 0.68）和另外两个越南南部森林（马大林业和富国岛；分别为 ρsr = 0.61 和 0.71）的植物区系组成的比较没有揭示显着的相似之处。然而，这些数据表明，在20多年的人工林中，已经形成了一个相对复杂的附生群落，在树冠中可以积累高达100公斤/公顷的沉积有机物和植物矿质养分。
