本文通过鹤庆古湖沉积物的孢粉记录对该区晚更新世的古植被和古气候进行了恢复。该区末次间冰期和末次冰期内部气候波动性特点与深海氧同位素记录有着较好的可比性，反映在全球变化的背景上，气候的不稳定性同样在本区有明显的响应。而且不同季风区气候资料对比也表明，本区冷湿和暖干的气候组合具有明显的区域特征，末次冰期该区夏季锋面降水增多，而间冰期则与之相反。造成这种区域环境效应的原因，与西南季风区大气环流的复杂性、云贵高原的地貌部位以及由青藏高原地表反照率引起的热力学和动力学过程有关。
In this paper, the ancient Pleistocene vegetation and paleoclimate recovered in this area through pollen record of the sediments of Heqing ancient lake. The characteristics of climate variability within the last interglacial and last glacial periods in this area are in good comparability with the deep-sea oxygen isotope records. It is reflected in the context of global change that climate instability also has obvious responses in this area. Moreover, the comparison of climatic data in different monsoon regions also shows that the climate combination of cold, wet and dry climate in this area has obvious regional characteristics, and the precipitation in summer increased in the last glacial period, while the interglacial period was the opposite. The causes of such regional environmental effects are related to the complexity of the atmospheric circulation in the southwest monsoon region, the topography of the Yunnan-Guizhou Plateau and the thermodynamic and kinetic processes caused by the albedo on the Tibetan Plateau.
