摘要
为揭示三峡地区地貌演化过程,利用GIS技术,基于DEM,建立起了地貌演化模型,提出了一种可形象直观地进行地貌演化模拟的方法,形象再现了50×104a前三峡地区的地貌形态,并对50×104a以来三峡地区地貌演化进行了过程模拟,结果表明50×104a以来,中部抬升幅度最大.
In order to reveal the evolution process of Three Gorges area, a geomorphy evolution modeling is set up on the basis of DEM by using GIS technology, and a visual method of geomorphy evolution simulation is presented. Geomorphy features of 500 000 years ago in this area, therefore, reappear and a process simula- tion is also carried out to demonstrate the geomorphy evolution of this area during the past 500 000 years. The result indicates that the lifting amplitude of midland is the highest in the past 500 000 years.
