摘　　要：通过对内蒙古巴彦淖尔花岗岩石林的调查和研究,对其形态类型和成因作了详尽的阐述。研究区的花岗岩石林从形态上可分为石柱、石锥、石蛋、蘑菇石、石排5种类型。根据形态特征的分析,该石林是由晚古生代花岗闪长岩—黑云二长花岗岩经重力崩塌、风化、流水侵蚀等外力作用而形成的一种特殊地貌,其形成发育受岩性、地质构造、气候条件等因素的控制。Based on the field investigation on the granitic stone forest in Bayan Nur, Inner Mongolia, in this pa- per the features and formation causes of the granitic stone forest were discussed in detail. The granitic stone forest was divided into five types, i.e. the stalagnate , talus cone, stone egg, mushroom stone to the morphologic features of the granitic stone forest, it was considered that the stone and stone row. According forest is a kind of special landform and formed from the Late Paleozoic granodiorite-biotite monzonitic granite under the effect of external forces, such as gravitational collapse, weathering, water erosion and wind erosion. The formation and development of the stone forest are affected by lithology, geological structure, climate conditions, etc.
