高山冰川前缘地带景观生态的发育与演替──以天山1号冰川前缘为例

The Development and Evolution of Landscape in Front of Alpine Glacier──A Case Study from the Front Area of No. 1 Glacier in Tianshan Mountain

高山冰川前缘地带长期处于高寒的冰缘环境背景之下，其生态系统的发育具有原始性和简单性，随着冰川作用时间长短的变化，其冰碛母质、植被和土壤同步演替，并表现为一定的演替模式（植被：微生物→藻类→地农、苔藓→高山亚高山植物；土壤：原始土→新成土→寒冻雏形土）；在景观上也呈现出明显的生态分异特征。

Under the background of alpine periglacier environment for a long time, thedevelopment and composition of ecosystems are of simplicity and originality in front area ofalpine glacier- With the change of the time of glaciation,the evolutional processes of parentmaterials of moraines, vegetation and soil have same space (Vegetation: microbe-algaelichen -moss -alpine meadow; Soil: primitive soil -orthic entisol -cryic combisol ). andlandscape has obvious ecological differential features.
