摘　　要：对榕树在热带雨林生态系统中的地位进行了研究和分析 ,并对聚果榕、鸡嗉果榕的成熟果实进行了成分分析。结果表明 :除糖、脂肪、蛋白质等营养成分外 ,聚果榕、鸡嗉果榕的榕果均含有丰富的矿质元素和多种人体必需氨基酸 ,维生素 C的含量特别丰富 ,分别为 0 .68mg· g-1和 0 .2 8mg· g-1。矿质元素中 ,以钾、钙、镁的含量最为丰富。榕果能为食果动物提供全面而均衡的营养成分 ,榕果具有数量多、产量高、一年四季均挂果的特点 ,是热带雨林生态系统食物链的重要组成部分。Fig trees are a keystone species in the ecosystem of tropical rainforest in Xishuangbanna.Fig trees provide habitats and food for many animals.Among figphagous animals,the frugivorous animal has the largest size except pollinators and others are leafphagous animals and trunkphagous ones sequently.Fig trees have a high comprehensive utilization value.Its shoot can be used as vegetable.Many parts of the fig tree can be used as medicine such as root,bark,leaf and syrup.Figs can be consumed as fresh fruit and are a good kind of stock food. The fig nutritional elements of Ficus recemosa L.and Ficus semicordata Buch. Ham. were analyzed. They are rich in mineral elements and amino acids besides common nutritional components such as sugar,grease and protein.Particularly,there is very rich vitamin C in the figs comparing with other common tropical fruits. The amount of Vc in the two figs mentioned above are 0 68 mg·g -1 and 0 28 mg·g -1 respectively.The richest mineral elements are K,Ca and Mg.Figs can provide a full and balanced diet for frugivorous animals. They are rich in quantity and available all the year. Figs play an inportant role in the food chain in tropical rain forest ecosystem.
