摘　　要：措勤东部属于极端缺水的地区,利用遥感技术开展第四系松散堆积物含水性调查具有重要作用。本文选用ETM753与8波段融合图像作为遥感解译底图,结合地形地貌、地质和气象影响,建立残积、冲积、洪积、冲洪积、冰川永久积雪、湖积、沼泽和坡积的识别知识体系,划定第四系松散堆积物的高、中、低、差四个含水等级,利用G IS实现第四系松散堆积物及其含水性的高程、坡度和坡向分布,为区内水资源的深入调查提供有力支持。Eastern Cuoqin belongs to extreme water shortage region, and it is important to investigate water-bearing ability of Quaternary loose deposit by using remote sensing. This paper selects ETM753 and 8-band to fuse image as interpreting image, considering topographic, geomorphic, and geological effects. It establishes recognition knowledge system of residual deposit, alluvial deposit, diluvia material, alluvial-proluvial, permanent snow and glacier, lacustrine deposits, swamp, and colluviums. Then, it defines four grades of loose deposit of Quaternary, including high, medium and low, and poor. Finally, it uses GIS to analyze the relationship among Quaternary, loose deposit and spatial information including elevation, slope and aspect. This research can be used in deeply water resources investigation.
