Abstract:
The data of Cenozoic sporopollen fossils obtained from ZKA01 drill hole in Leizhou Peninsula of Guangdong Province were systematically analyzed.Through the analysis of spore-pollen data, 8 sporopollen assemblages can be recognized from this drill hole.In the late Oligocene, the vegetation types in this area reflected the obvious vertical distribution of vegetation; coniferous forests were distributed in the surrounding mountains, and deciduous broad-leaved and evergreen broad-leaved mixed forests grew in the plain.In the early and middle Miocene, the vegetation types in this area evolved from deciduous broad-leaved and evergreen broad-leaved mixed forests into evergreen broad-leaved forests and tropical rainforests.In the late Miocene, the vegetation types in this area evolved into coniferous forests in mountain areas and deciduous broad-leaved and evergreen broad-leaved mixed forests in plain areas.During the Pliocene-Early Pleistocene period, the vegetation types in this area were deciduous broad-leaved and evergreen broad-leaved mixed forests, and the temperature changes fluctuated significantly.The climate change characteristics of Late Oligocene to Early Pleistocene period were reflected by spore-pollen assemblages, which had good comparability with the trend of global climate change.
