Phytocenotic Characteristic of the Achnatherum splendens (Trin.) Nevski Communities of Western Transbaikalia

摘要

The phytocenotic characteristics of cheegrass (Achnatherum splendens (trin.) Nevski) communities developed on solonchaks in the haloxerophytic steppe of western Transbaikalia are given. The specific features of their composition and structure have been revealed. The similarity of the species composition of cheegrass communities is slight or medium. The botanical composition accounts for 14 species of halophytes and 17 species of halotolerant glycophytes. The communities and their production are mainly formed by three to four species, including the dominants. The production of the cheegrass communities is at a normal level (1626 g/m2 per year).
