摘要
第四纪自然环境的形成和演变是第四纪地质史研究的中心环节。第四纪时全球的气候变化与青藏高原的强烈隆升,是影响贵州自然环境的重要因素。由于地势升高、气候变化与生物演化等,贵州第四纪自然环境经历了巨大复杂的变化。
The formation and evolution of Quaternary natural environment is the key link of Quaternary geological study. The changes of Quaternary natural environment include crustal movement, climatic changes and biotic evolution, etc.
Guizhou Plateau was initially formed in Early Pleistocene with the rising of Qinghai -Xizang Plateau, with the climate mild and humid at that time. The magnificent , Guizhou Plateau, was finally formed in Middle Pleistocene due to strengthening of the crust uplift. In fluenced by the climate which was getting cold and the rising of land, glaciers were developed on the Plateau, with moist-heat interglacial period in Late Pleistocene. The Late Pleistocene underwent changes from glacial age to interglacial period and then to glacial age, but glaciers occurred on the Plateau only in the Lushan glacial age. The rising of land was the main feature of Guizhou crustal movement in Holocene, undergoing long evolution since Quaternary and forming the present plateau features, the climate approximately similar to that of today.
