| Abstract: | A peat section at Riganqiao region was systematically studied using the 14C method and sporopollen analysis, three ecological zones could be recognized during these periods. The climate evolution in the Hongyuan area since the Late-glacial epoch reflected by sporopollen records experienced a wet-dry-wet climate change process. |
