中文摘要	沙漠河岸作为独特的地理单元,在世界主要沙漠中普遍存在,风水复合地貌过程是其独特性的突出表现.以塔克拉玛干沙漠策勒河为例,利用" 3S"技术,对策勒河下游地区70年代以来四期Landsat卫星图像,分析近40a以来的风水复合地貌过程的时空变化和分布特征.结果表明:策勒河下游地区风水复合地貌过程可以分为流水地貌过程为主、风力地貌过程为主以及风水复合地貌过程为主三种类型;流水地貌过程主要表现间歇性流水河道的变迁、冲沟的盈涸及其冲洪积扇流水出露在一定程度上影响沙丘发育过程;风力地貌过程主要发生在河流绿洲边缘流动沙丘地带,表现为河岸沙丘侵入河道;风水复合作用区,风沙和流水交互作用影响沙丘发育过程,风力作用促使沙丘顺着主风向延伸,流水作用则削弱沙丘的发育过程.本研究有助于理解干旱区风水复合地貌过程演变机制,丰富风沙地貌的相关研究内容,实践上为沙漠绿洲的生态保护和防沙治沙工程提供科学依据.
英文摘要	River banks in deserts are unique geographical units due to the prominent processes of aeolian - fluvial interactions occurring in such environment. taking the Qira River in the Taklimakan Desert as an example,the "3S" technology was used to measure the temporal and spatial changes and distribution characteristics of aeolian - fluvial geomorphology processes in the past 40 years. The results show that the geomorphic processes in the lower reaches of the Qira River can be divided into three types: flowing water and geomorphic processes,wind and geomorphic processes,and aeolian - fluvial complex geomorphic processes. Flowing water and geomorphic processes are mainly characterized by temporary changes in river courses and their impacts. The wind and geomorphic processes mainly occur in the areas with low vegetation coverage on the upwind of the oasis and on the edge of the sand dune without transient water flow. This is reflected by river bank dunes intrusion into the river channel. The geomorphic process of aeolian - fluvial mainly occurs temporarily. The flow of water on the edge of the dunes shows that the flow can slow the movement of the sand dunes both directly and indirectly. The results of this study help to understand the evolution mechanism of the geomorphic process of the aeolian - fluvial in arid areas and enrich the related research contents of the wind and sand landforms. In practice,it provides a scientific basis for the ecological protection of desert oasis and desertification control projects.
