淮河作为中国7大江河之一,有关其形成时代的研究相对匮乏且存在较大的争议。论文通过梳理淮河流域内已有的研究工作,综合层状地貌面和沉积地层记录探讨了淮河不同河段的形成时代。新生代期间,淮河流域内的水系曾经历2次较大的调整,分别发生在古近纪末和上新世末。古近纪和新近纪期间,淮河流域曾广泛发育湖泊沉积,以河湖相沉积环境为主。而第四纪期间,流域内古地理环境逐渐过渡为以河流相沉积环境为主。现代淮河河湖体系的形成发生在早至中更新世,其后经历不断的演变至今。构造活动和气候变化是驱动淮河流域水系演变的主因。上新世末至早更新世初的青藏运动导致了淮河流域内新近纪水文体系的解体...

Development and evolution of large rivers is a classic subject of geomorphology. As one of the seven large rivers in China, the Huaihe River locates in China's north-south transitional zone. However, there is much controversy about its formation and development. In this study, we explored and discussed the formation of different sections of the Huaihe River based on the analysis of topography and sedimentary stratigraphy. The results show that there were two major adjustments of the river system in the Huaihe River Basin during the Cenozoic period, which occurred at the end of the Paleogene an...
