摘　　要：运用GIS技术并且结合现场踏勘,以辽宁省桓仁县广泛分布的裸露型岩堆为研究对象,分别选取独立岩堆体和单个珊格作为分析单元,从高程、表面坡度、表面坡向三个空间维度进行分布特征分析,并结合现场踏勘耦合研究。结果表明:研究区内裸露型岩堆只在震旦系下统钓鱼台组(Z1d)有分布,岩性全部为石英砂岩;裸露性岩堆主要分布的高程为400～800m,坡度25°～40°,坡向为东北向。With the help of Geographic Information System（GIS）and ground observation, the distribution characteristics of the bare rock pile in Huanren County, Liaoning Province is researched. Both the independent rock piles and single grid are selected as the analysis units to reveal the distribution characteristics from different elevation, slope gradient and aspect,and combined with on-site exploration coupling research.. The results show that the bare rock pile in the study area are only distributed in the Diaoyutai Formation（Z1d）, and the lithology is quartz sandstone with 400~800m as the main elevation , 25℃-40℃as the main slope gradient and northeast as the aspect.
