| 摘 要： | 下荆江河势演变过程及特点是因其所处的特殊地质环境决定的 ,作为动力因素的水文条件也受地质环境的制约。只有深刻理解水文条件与河道地质环境相互作用过程与演化趋势对下荆江河道演变的决定性作用 ,才能找出合乎实际、科学的河势控制方案。阐述了下荆江演变过程及特点、所处的区域地质环境 ,分析了形成这些特点的基本原因 ,论述了建国后控制河势的过程和基本经验教训 ,分析了今后进一步控制下荆江河势的原则要求。

| Abstract: | The process and characteristics of its river pattern change depend on its unique geologic environment.The hydrologic condition,as a dynamic factor is also restricted by geologic environment.Only by understanding the decisive effect of the interaction process and change tendency of the hydrologic condition and the channel geologic environment on the channel change of the Xiajingjiang River can a practical scientific scheme for controlling the river pattern be worked out.The change process as well as its characteristics,and the geologic environment in the region is expounded.The basic reason why these characteristics are formed is explained.The process of controlling river patterns and the main experience and lessons after the founding of our country are analyzed and foundamental.requirements for the further control of the river pattern are discussed. |
