摘要: 本文以乌鲁木齐河源区和沙湾县为例,讨论天山现代冰缘环境中多年冻土带发育的石冰川的形态、大小、类型、发育条件和形成年代等问题.石冰川主要出现在年均温0~-9℃的阴坡或半阴坡,形成于10000a,B.P以来.

Abstract: Based on field survey and air photo interpretation, the shape, size, type, environmental condition, and forming date of the rockglaciers are considered in permafrost belt of the periglacial area at the Tianshan Mountains. Small size talus-typed rockglaciers are predominant in the head area of the Urumqi River, while on halt of the rockglaciers are large moraine-typed in Shawan County. The rockglaciers are distributed at the areawhere mean annual air temperature is 0-9℃, and mostly on northward slopes. Therockglaciers formed since 10000a B. P.
