摘要: 研究区位于天山乌鲁木齐河源区海拔3000m以上的高山冰缘环境中。末次冰期冰碛和新冰期冰碛上发育高山草甸土,海拔3000-3700m.小冰期冰碛上发育高山寒冻土,海拔3700-3800m.土壤的剖面结构、粘土矿物组成和化学成分分析均表明土壤的发生演化与冰川作用密切相关。

关键词: 冰碛, 土壤, 粘土, 冰期

Abstract: The research area is located at the head area of Urumqi Rjver,above 3000m and in al-pine periglacial environment.On the moraines of the Last Glaciation and Neo-glaciation al-pine meadow soils develop from 3000 to 3700 m.On the moraines of Little Ice Age alpinefrost soils develop from 3700 to 3800 m. The profile patterns,clay minerals and oxides of thesoils show that the pedogenesis and evolution of the soils is related to glaciations.

Key words: moraine, soil, clay, glaciation
