中国东部季风区表土孢粉组合数据集（现代）

通过对我国东部季风区现代表土样品孢粉组合与气候因子之间的回归分析，分别建立孢粉组合与一月、七月气温和年降水量的转换函数，进而建立了本区末次冰期以来的孢粉-气候数据库，模拟末次冰期盛冰期、消冰期、全新世前北方期-北方期、大西洋期、亚北方期等五个古气候期的冬季和夏季温度场、降水场。结果表明：1)本区气候变率与全球气候变率明显不同。其中，末次冰期盛冰期的降温幅度低于欧洲大陆，而全新世高温期的升温幅度则比欧洲大；2)无论末次冰期还是全新世各气候期，气温和降水量的纬度地带性规律仍然存在，表现在气温的南高北低和降水量的南多北少；3)各气候转型期，本区气候湿热组合特征也与现代一致，表现为雨热同期。

Through regression analysis between pollen assemblages in modern topsoil samples and climatic factors from the eastern monsoon region of China, transfer functions linking pollen assemblages to January and July temperatures as well as annual precipitation were established separately. Subsequently, a pollen-climate database for this region since the Last Glacial Period was developed, which was utilized to simulate winter and summer temperature fields and precipitation fields for five paleoclimatic periods: the Last Glacial Maximum (LGM), deglaciation period, Preboreal-Boreal, Atlantic, and Subboreal stages of the Holocene.
The findings indicate that:
1) The climatic variability in this region differs notably from the global climatic variability. Specifically, the cooling magnitude during the Last Glacial Maximum was lower than that observed across the European continent, while the warming magnitude during the Holocene Thermal Maximum (HTM) was greater than that in Europe;
2) Latitudinal zonality of temperature and precipitation persists across all climatic periods of both the Last Glacial Period and the Holocene, characterized by higher temperatures in the south and lower temperatures in the north, as well as more precipitation in the south and less precipitation in the north;
3) The humid-hot climate combination pattern of this region during all climate transition periods is consistent with the modern pattern, manifesting as synchronized occurrence of warm and wet seasons.
