一、前言河道分汊研究是我国解放以来重点研究课题之一。用历史地貌学研究河道分汊已成为必要手段。无论从地貌学的数量化和生产建设部门的要求上,对地貌发育和演变要有年代上的确定,才能计算出所需要的参数,而历史地貌学正可达到这一目的。因为它的任务之一就是要研究古代地貌的情况。本文目的即在于介绍用历史地貌学方法去论证今天地貌形成的过程,并且具体 I. Introduction The study of river division is one of the key research topics since the liberation of our country. It has become necessary to study the watershed division with historical geomorphology. No matter from the quantification of geomorphology and the requirements of production and construction departments, the determination of geomorphologic development and evolution should be determined on the basis of the age before the required parameters can be calculated, and the historical geomorphology can achieve this goal. Because one of its tasks is to study the ancient landscape. The purpose of this paper is to introduce the process of using historical geomorphology to demonstrate the formation of today’s landscape,
