摘要
本文提出表达河漫滩发育特征的定量指标,并根据这一指标将河漫滩发育分为垂直加积型、过渡型和侧向加积型。在此基础上对河漫滩发育模式与河型特别是与气候因子的关系进行探讨。通过研究对河流发育过程中的古地理环境变迁作出一定的推论。从而对地质历史时期中区域环境的重建提供佐证。
A quantitative index expressing the developing characterisics of carse is given in this paper by which the development of carse are divided into three types, vertical additive deposition, transition and Lateralness. It is discussed that the relationships between the developing model ofcarse and river types, especially-the climatic factors on the basis. It is given that some conclusions on the changes of the ancient geographic envionment in the developing process of river, and the evidences are supplied rebuild the regional environment during stratigraphic historical period.
