| 摘 要： | 为了探讨湘桂走廊内岩溶发育特征、水文地貌学意义及区内峰林平原形成原因，文章通过实地调查区内地貌形态、岩性以及地貌类型的空间展布特征，运用岩溶水文地貌学理论探讨区内水文地貌的形成与演化。根据区内地貌形态的空间展布特征，分析认为区内水系经历一次反向袭夺过程；区内地貌演变受到越城岭、海洋山两个隆起的影响，平原面积变小，湘江向东北退缩；区内地貌演化至少经历了古湘江期、灵河孕育期、灵河期等三个夷平时期。文章在分析区内峰林平原形成动力机制的同时，提出岩溶流域潮间带概念模型和岩溶流域牵动交互式袭夺模式，丰富了峰林平原成因类型和岩溶水文地貌学的研究方法，提出的科学术语具有重要科学意义。

| Abstract: | To explore the karst development characteristics， hydrogeomorphological significance and the causes of formation of peak forest plain in Hunan-Guangxi Corridor，in this paper，the investigation of spatial distribution characteristics of landforms， lithology and landform types in the area are conducted ，and the formation and evolution of hydrogeomorphology are discussed under the guidance of karst hydrogeomorphology theory.The analysis of the spatial distribution characteristics shows that the water system in this area has undergone a reverse seizure process； its regional geomorphic evolution is affected by the uplift of Yuechengling and Haiyangshan mountains， which has led to the narrowing of the Hunan-Guangxi Corridor and diversion of the Xiangjiang river to northeast. The geomorphic evolution has experienced at least three flattening periods， the ancient Xiangjiang period，the Linghe incubation period， and the Linghe period. In addition，the concept model of the karst basin intertidal zone as well as the interactive capture mode of karst basin are put forward for the first time when the formation dynamic mechanism of peak forest plain is analyzed， which enriches the genetic type of peak forest plain and the research methods of karst hydrogeomorphology. The scientific terms put forward here is also of important scientific implications. |
