摘要: 塔克拉玛干沙漠优势植物化学成分的若干特征与土壤盐分的性质相联系,对优势植物及植物群落的化学元素特征型、盐生植物类群的划分进行了讨论。在塔克拉玛干沙漠环境中,藜科植物占有一定优势、且含有较高的可溶性盐分和灰分,而海蓬子、盐节木、盐穗木是一类富含Na和Cl的植物,芦苇、小獐毛是富含SiO2的植物。

Abstract: This paper dealt with the chemical composition characteristics of dominant plant species in the Taklimakan Desert.Some characteristics of the dominant species are closely related to the soil salt properties.Based on the chemical element characteristics of the dominant plant species and associations,a simple classification of halophyte types was made.Chenopodiaceous plant are the most common dominant species of the desert and have a higher soluble salt contents.Such plants as Salicomia europaca.Halostackys caspica and Halocnemum strobUaceum etc.are Nacl-rich species,whereas Phragrmies communis and Aeluropus litaralis etc.are Si-rich species.

Key words: Dominant plant, Chemical composition, Taklimakan Desert
