摘要
在作者曾对长江中下游河道平面形态进行统计和河型分类的基础上，本文对不同河型的形态指标作了进一步分析，获得了不同河型的平面形态诸因素之间的关系及河型转换中的形态条件，初步阐述了形态分析在河道整治中的作用。
Based on the investigation of natural reaches of the Middle and Lower Yangtze River andthe classification of their channel patterns, this paper analyses the geometry criterion of various channel patterns in detail, and obtains the different relations between geometry elements and the transform-ing conditions. Finally, it is stated that geometry analysis plays an important part in river regulation.
