摘　　要：与上海科技馆生物万象展区内人工光照下热带雨林植物的养护相结合,本文探讨了大型室内热带雨林地区植物的光合作用特性。结果表明,展区中大部分植物叶绿素a/b较低,被测的4种植物的叶绿素a/b为2.57～2.85,表现出对弱光的适应性。展区内CO2浓度较高(约800～900 mol.L-1),这有利于植物在弱光下的生长。适生于展区环境的植物有爬树龙(Rhaphidophora decursiva(Roxb.)Schott)、红宝石(Philodendron erubescens CV.Red Emerald),鸡蛋花(Plumeria rubra var.acutifolia)、篦齿苏铁(Cycas pectinata)、酒瓶椰子(Hyophorbe lagenicaulis)。The photosynthesis of the tropical rainforest plant in the exhibition area with weak artificial illumination in Shanghai Science ＆ Technology Museum was studied. The result showed that plants in the exhibition area express the adaptability of the weak light,such as their chlorophyll a/b ratio is lower. The chlorophyll a/b ratio of the tested plants is 2.57-2.85. In the exhibition area, CO2 concentration is higher （about 800-900 mol · L^-1） that benefit for the plants in shade. There are Rhaphidophora decursiva （Roxb.） Schott, Philodendron erubescens CV.Red Emerald, Plumeria rubra var.acutlfolla, Cycas pectinata and Hyophorbe lagenicaulis suit for the condition like this area.
