Abstract

We studied plant biodiversity (trees, shrubs and herbs) in two kinds of forests, natural and coffee agro forests and comparing diversity of plant species between them. The natural forest contained 63 plant species in total, of which 44 were trees, 5 were shrubs, and 14 were herbs. The planted forest, on the other hand, contained 42 species of flora, including 35 trees, 1 shrub, and 6 herbs. In the natural forest, the ShannonWiener diversity indices for trees, shrubs, and herbs were 3.26, 1.53, and 2.57, respectively. In the coffee agro forest, it was 2.91 for tree species, 0.00 for shrub species, and 1.77 for herb species. Simpson diversity index were 0.95, 0.77 and 0.91 for trees, shrubs and herbs respectively in the natural forest. However, it was 0.92 for tree species, 0.00 for shrub species and 0.82 for herb species in the coffee agro forest. Jaccard’s similarity index showed that 72% species of trees, 20% species of shrubs and 33% species of herbs were same in natural and coffee agro forest.

印度安得拉邦东高止山脉天然林与咖啡农业林植物物种多样性比较研究
我们研究了天然林和咖啡农业林两种森林的植物多样性(乔木、灌木和草本植物),并比较了它们之间的植物物种多样性。天然林共包含63种植物,其中乔木44种,灌木5种,草本14种。人工林则有42种植物,其中乔木35种,灌木1种,草本6种。天然林中乔木、灌木和草本的shannon - wiener多样性指数分别为3.26、1.53和2.57。在咖啡农业林中,乔木树种的比值为2.91,灌木树种为0.00,草本树种为1.77。天然林乔木、灌木和草本的Simpson多样性指数分别为0.95、0.77和0.91。而咖啡农业林中乔木、灌木和草本树种的平均密度分别为0.92、0.00和0.82。Jaccard相似指数表明,天然林和咖啡农林有72%的乔木、20%的灌木和33%的草本植物相同。
