摘要
本文通过地质、地貌和古水文调查资料的分析,并结合计算机数值模拟研究讨论了冰后期海面上升对长江中下游河床泥沙加积、水位变化,沿岸湖泊发育及荆江河曲形成的影响。
It has been confirmed by previous studies that intensive channel aggradation and water-stage rise have happened in the middle and lower reaches of the ChangJiang River during the postglacial period. In the study, a deductive analysis, based on the results of geological, geo-morphological and archaeological surveys, shows that these changes possibly resulted from sea level rise after the last glacial maximum. This is confirmed further by our simulation modelling on the impacts of postglacial sea-level change on the ChangJiang River. The simulating outputs provide a reasonable explanation to the channel headward aggradation, water-stage rise, development of the Jinjiang meander and to the origin of the lakes along the river.
