依据滇西北鹤庆盆地 1 68m钻孔花粉资料 ,对该区 1 .0 Ma BP以来的古植被演替与气候变化的阶段性特征进行了研究 ,探讨了该区植被和气候对高原隆升不同阶段的响应特点。明显的气候转型发生在 0 .73Ma BP和 0 .42 - 0 .365Ma BP。 0 .1 7Ma BP前后 ,山体抬升引起的树线植被响应不甚明显 ,可能与山体上升到一定高度和垂直带谱的稳定形成有关。 1 3.2 ka BP,构造的差异升降和气候变化导致湖盆被切穿。 Based on the data of 68m boreholes in Heqing Basin, Northwest Yunnan, the characteristics of the succession of ancient vegetation and the features of climate change since 1.0 Ma BP in this area were studied. The effects of vegetation and climate on the uplift of the plateau were discussed Phase response characteristics. The obvious climate transition occurred at 0 .73 Ma BP and 0 .42 - 0 .365 Ma BP. Before and after 0.1Ma BP, the response of the tree line vegetation caused by the mountain uplift was not obvious, which may be related to the stable formation of the mountain up to a certain height and vertical band spectrum. 1 3.2 ka BP, differences in tectonic movements and climate change cause the lake basin to be cut through.
