On the base of the classification statistic of Mesozoic and Cenozoic pollen and spore data in the different depression of Erlian basin
the paleoclimate was reconstructed depending on the different parent vegetation eco-environment of the pollen and spore. Meanwhile
according to climatic indicator of Erlian basin’s lithofacies and continental special deposits
the paleoclimate was reconstructed by the qualitative analysis. Then paleocliamite evolution rule of Erlian basin from Mesozoic to Cenozoic can be concluded by the contrast of spore-pollen quantitative analysis and deposits-indicator qualitative analysis.
