摘要

本文详细研究了黄河清水沟裂片近30年来的演化过程。自1976年以来，合成假彩色遥感图像用于检测岸线和河道的变化。利用1976 ~ 2005年的水深资料，研究了清水沟裂片水下三角洲的沉积和侵蚀模式。作为对清水沟河道演化的响应，水下三角洲的演化分为4个阶段，即多中心沉积阶段、单一稳定沉积阶段、缓慢沉积阶段和沉积侵蚀阶段。在此基础上，探讨了影响三角洲裂片演化的因素。

EVOLUTION OF THE QINGSHUIGOU SUBAQUEOUS DELTA LOBE OF YELLOW RIVER

The evolution of the Qingshuigou lobes of the Yellow River in the past 30years is studied in details in this paper.Composite false color remote sensing images since 1976 were used for detecting the changes in shoreline and river channels.Bathymetric data from 1976 to 2005 were processed for study of the depositional and erosional pattern of the subaqueous delta of Qingshuigou lobe.The evolution of the subaqueous delta was divided into 4 phases,multi-center depositional phase,single stable depositional phase,slow depositional phase and depositional erosional phase as the response to the evolution of Qingshuigou channel.Moreover,the factors influencing the evolution of the deltaic lobe were investigated.
