摘要
本文通过全国各油气区43个地区第三纪孢粉序列的深入研究,在编制孢粉母体植物生态表的基础上,首次建立了利用孢粉统计资料定量划分孢粉植被类型、气温带、干湿度带三个模式,并对第三系分统进行了孢粉植被类型、孢粉气温带、孢粉干湿度带的定量划分。研究成果揭示了我国第三纪各时期的气候特征及其演化。
Based on a thorough study of tertiary spore-pollen sequence from 43 hydrocarbon-bearing regions in China, and a compiling of an ecological table of spore-pol-len parent plants belonged to more than 130 genera. Three patterns for a quantitative classifi-cation of vegetation category climatic zone, aridity and humidity, using spore-pollen statisti-cal data, have been establish for the first time. Quantitative classifications of vegetation cate-gory, climatic zone, aridity and humidity in Tertiary have been accomplished, showing theclimatic characters and its evolution at different times during Tertiary period in China.
