摘要
本文对从小凌河口至山海关的辽西海岸地貌类型及其主要特征进行了讨论。辽西滨岸地貌在发育过程中因受构造体系、新构造运动、海平面变化及河流物质供给等因素的影响,具有明显的阶段性、填充性和复杂性的特征。并对晚更新世以来古地理环境的演变进行了探讨。
The coastal geomorphic types and main characteristics of the west part of Liaoning Province were discussed in this paper.The development of the geomor- phic features of the west coast of Liaoning was influenced by structural system, neotectonic movement,eustatic changes and materials supplied by rivers.There- fore,it showed some remarkable features such as the periodicity,and complica- tion.Based on the core data,sporo-pollen assemblage and microfossils,the paleogeographic environment since the late Pleistocene was studied.According to map comparison and material supply,the deposition-erosion tendency was analysed of modern beaches.
