| 摘 要： | 以第四纪构造活动、沉积作用以及现今地势高低和地貌形态特征为主要依据,对江汉-洞庭盆地东部中段及其东缘(1:25万岳阳市幅)进行构造-沉积地貌类型的划分与编图。研究区共厘定出9种构造-沉积地貌类型,各地貌类型的地表高程、第四纪地壳升降特征、风化剥蚀和沉积作用等各具特征。构造-沉积地貌类型的划分及其地貌图的编制,既反映出地表地理环境暨地貌特征,又提供直观表达不同地区第四纪地层、构造特征及其反映的地质与环境演化过程的有效途径,有助于促进和深化江汉-洞庭盆地第四纪地质与环境研究。

| Abstract: | Tectonic-sedimentary landforms classification and mapping of the middle segment and eastern areas of east Quaternary Jianghan-Dongting basin (1:250000 Yueyang sheet)were conducted according to Quaternary tectonic activity, sediment and present elevation and topographic characteristics. Nine types of tectonic-sedimentary landforms were defined, and every type of landforms possess special characteristics of elevation, quaternary rising-falling activity, weathering and erosion and sedimentation. Tectonic-sedimentary landforms classification and geomorphologic map not only show geographic environments, but also provide a effective mean to deliver directly Quaternary stratum, tectonic features and geological and environmental evolution, and will promote and deepen studies on the Quaternary Geology and environment of Jianghan-Dongting basin. |
