| 摘 要： | 松潘黄龙自然保护区第四纪冰川遗迹十分发育，在三岔子一带冰碛物出露齐全、保存完好。通过剖面的测制，再结合孢粉、ESR测年样等成果综合研究，将该地区划分为四次冰期，三次间冰期，Ⅳ个孢粉组合带。阐明了冰川活动与成景作用关系密切，黄龙钙华景观的雏形是在中更新世末形成，大量钙华堆积形成了晚更新世。

| Abstract: | Quaternary glacial vestige is well developed in the Huanglong Nature Reserve, especially, in the Sanchazi Valley. On the basis of profiling in combination with sporopollen analysis and ESR dating, the Quaternary ice age in this region may be divided into 4 glacial stages, 3 interglacial stages and 4 sporopollen association zones. Glaciation was in close relationship with landscape formation. The undeveloped forms of the Huanglong Travertine Landscape were formed at the end of the Middle Pleistocene, while a great amount of travertine accumulation were formed in the Late Pleistocene. |
