摘　　要：大别山北麓的六安市境内分布有典型的丹霞地貌,目前具有代表性的主要包括皖西大裂谷、大别山石窟和嵩寮岩等3处。在前期对该地区丹霞地貌进行实地调查的基础上,通过现场统计、文献检索和景观对比等方法,对大别山北麓地区丹霞地貌的地学背景和景观特征进行了分析和研究。研究认为大别造山带的动力机制、山前盆地构造和凤凰台组红色砂砾岩等是该地区丹霞地貌发育的基本条件。在此基础上,通过对该地区丹霞地貌的形成机理和景观分类的研究,认为该区丹霞地貌具有岩层沉积相变化、丹霞地貌发育阶段的多样化、地貌景观组合特征典型和透镜体微观结构较为发育等特征。该研究为今后对大别山北麓丹霞地貌的沉积环境、岩石学特征、丹霞地貌发育与大别山构造的关系以及丹霞地貌的旅游开发等研究打下了基础。There are some typical Danxia landforms at the northern slope of Dabie Mountain,Lu＇an City.Its representative includes West Anhui Great Rift Valley of,Dabie Mountain Grottoes and Songliaoyan.On-the-spot investigation of the Danxia Landform in the early stage,through the field statistics,document retrieval and landscape contrast method,we had analyzed geological background and landscape characteristics of Danxia landform on the northern foot of the Dabie Mountain in this paper.The results showed that the Dabie mountain orogenic belt driving mechanism,the foreland basin tectonic and Fenghuangtai Group red sandy rocks,is the basic condition for the development of Danxia Landform in the region.On this basis,through the study of the formation mechanism and landscape classification of the Danxia landform in this area,its characteristics include Danxia landform has the change of strata sedimentary phases,the diversification of development stage of Danxia landform,the features of landscape composition is typical and the micro structure of the lens.The paper is the foundation for the study of Danxia landform sedimentary environment,petrology,the relationship of Danxia landform development and Dabie Mountain tectonics and Danxia landform tourism development.
