Eocene palynological samples from 37 widely distributed sites across China were analysed using co-existence approach to determine trends in space and time for seven palaeoclimate variables: Mean annual temperature, mean annual precipitation, mean temperature of the warmest month, mean temperature of the coldest month, mean annual range of temperature, mean maximum monthly precipitation and mean minimum monthly precipitation. Present day distributions and observed climates within China of the nearest living relatives of the fossil forms were used to find the range of a given variable in which a maximum number of taxa can coexist. Isotherm and isohyet maps for the early, middle and late Eocene were constructed. These illustrate regional changing patterns in thermal and precipitational gradients that may be interpreted as the beginnings of the modern Asian Monsoon system, and suggest that the uplift of parts of the Tibetan Plateau appear to have taken place by the middle to late Eocene.
对来自中国 37 个广泛分布地点的始新世孢粉样品进行了共存分析，以确定七个古气候变量（年均温、年降水量、最热月均温、最冷月均温、年均温差、最大月均降水量和最小月均降水量）在空间和时间上的变化趋势。利用化石形态最近的活体亲属的现代分布和观测到的气候，确定了一个给定变量的范围，在此范围内可以最大限度地共存多个分类单元。构建了早、中、晚始新世的等温线和等雨量线图。这些图说明了热梯度和降水梯度的区域性变化模式，可解释为现代亚洲季风系统的开端，并表明部分青藏高原的隆升可能发生在中到晚始新世。
