摘要
新疆天山中部的大尤尔都斯盆地,是世界著名的天鹅保护区,由于受特殊地理位置及地形的影响,该区域植被分布以高山沼泽植被及高山草甸、草原植被为主。
In the Big Youerdosi Basin, dominant environmental factors affecting vegetative distribution are soil moisture, saIt and SO_4^- contents. Carex. and Stipa purpurea + Festuca sulcata formations are affected mainly by soil moisture content. The former is distributed only in places where moisture content is larger than 30%, and the latter is only distributed in where moisture content is less than 30%.The distribution of Leymus secalinus formation is dominated by soil SO_4^- content.
