摘　　要：呼伦湖是东北亚典型的新生代构造湖盆,通过大量卫星观测数据、GIS平台成图,从区域地质角度总结了呼伦湖地区的地质地貌特征,内容涉及呼伦湖构造特征、演化历史、湖岸侵蚀、地貌水系等。文章将呼伦湖与我国东北地区海拉尔断陷盆地的发展演化相结合,揭示了环太平洋构造带岩石圈伸展作用对呼伦湖构造演化的重要意义。研究结果可以建立呼伦湖中、新生代以来构造演化历史,对“呼伦贝尔景观和中国东北古代少数民族发源地”申报世界遗产的研究有重要帮助。Hulun Lake is a typical Cenozoic tectonic lake basin in Northeast Asia.This article summarizes the geological and geomorphological characteristics of Hulun Lake area from a regional geological perspective through a large number of satellite observation databases,GIS platforms and field visits.The content involves Hulun Lake structure characteristics,evolution history,lake bank erosion,geomorphic water system.Combining Hulun Lake with the development and evolution of the Hailar fault depression basin in northeastern China,this article reveals the significance of the lithospheric extension of the Pacific Rim tectonic belt to the Hulun Lake structural evolution.This study can establish the history of tectonic evolution of the Hulun Lake in the Mesozoic and Cenozoic times,and is of great help to the study of“Hulun Buir Landscape&Birthplace of Ancient Minority Groups”to be declared as a world heritage.
