The paper on palynology and archaeology reveals the living environment of ancestor and the mutual relationship between human activity and environment change by pollen analysis of Qiguoshan Section in Chifeng Area. The results show that 8?400-6?200 a B.P., the climate was warm and moist with grassland vegetation, ancestors did hunting, fishing, planting and herding; 6?200-4?000 a B.P., environment changed gradually bad, and the agriculture level dropped with destroying forest; 4?000-?2?500 a B.P., climate was...

The paper on palynology and archaeology reveals the living environment of ancestor and the mutual relationship between human activity and environment change by pollen analysis of Qiguoshan Section in Chifeng Area. The results show that 8?400-6?200 a B.P., the climate was warm and moist with grassland vegetation, ancestors did hunting, fishing, planting and herding; 6?200-4?000 a B.P., environment changed gradually bad, and the agriculture level dropped with destroying forest; 4?000-?2?500 a B.P., climate was temperate and arid with grassland vegetation, ancestors planted dry crop; 2?500 a B.P.-today, vegetation was the typical grassland of Artemisia , with comparatively temperate arid climate, the agriculture and animal husbandry was comparatively developed, and influences of human activities on environment have been enhanced.

考古孢粉学角度 ,根据赤峰七锅山剖面孢粉分析 ,结合赤峰地区古文化遗址的考古资料 ,探讨了赤峰地区 80 0 0aB .P .以来的先人生活环境 ,以及人类活动和自然环境演变的过程之间的相互关系。结果表明 :84 0 0~ 62 0 0aB .P .为温暖湿润的草原气候 ,先人既狩猎捕鱼 ,也种植作物和放牧 ;6 2 0 0~ 4 0 0 0aB .P .,随着森林的破坏 ,环境逐渐恶劣 ,农业水平下降 ;4 0 0 0~ 2 5 0 0aB .P .植被以草原为主 ,气候温干 ,先人以旱作农业为主 ;2 5 0 0aB .P .至现在 ,植被为典型的蒿草草原 ,气候温和偏干 ,农业和畜牧业相对发展 ,人类活动加剧。

Great progress on Quaternary palynology has been achieved with the research of global change. The study on relationship between pollen, vegetation and climate has been one of the foci on palynology in the world especially in recent years. Studies on the air pollen have been applied extensively to various aspects including the monitoring of the air environment pollution, studying the allergic properties of pollen, agricultural yield prediction, and the reconstruction of vegetation and environment of Quaternary....

Great progress on Quaternary palynology has been achieved with the research of global change. The study on relationship between pollen, vegetation and climate has been one of the foci on palynology in the world especially in recent years. Studies on the air pollen have been applied extensively to various aspects including the monitoring of the air environment pollution, studying the allergic properties of pollen, agricultural yield prediction, and the reconstruction of vegetation and environment of Quaternary. In recent years, for developing study of paleo_environment in the world, the Pollen Databases have been set up globally, using surface pollen studies. The "China Quaternary Pollen Database"(CPD) was developed over a 50 year period. Using these pollen data from CPD, biome simulation and reconstruction of modern (0 kaBP), Middle Holocene (6 kaBP) and the last Glacial Maximum (18 kaBP) have been carried out systemically, while pollen_climate transfer function and pollen_climate response surface have also been established. Some headways have been made on the alluvial pollen and the Palynology of environmental archaeological sites, which have yet to be studied in depth. The study on pollen rain of characteristic indicator species has important significance for reconstructing paleo_ecological environment.

随着全球变化研究的不断深入 ,第四纪孢粉学研究已取得了长足的进步 ,特别是近些年来 ,孢粉 植被 气候关系研究已成为世界孢粉学界的热点之一。空气孢粉学的研究在大气环境污染监测、花粉过敏症、农业收成预报和第四纪植被与环境重建等方面得到了广泛应用 ,并不断发展 ;近年来 ,为开展全球范围的古环境研究 ,各大洲相继建立了孢粉数据库 ,大量开展表土孢粉研究。中国第四纪孢粉数据库的建立 ,汇集了我国近半个世纪积累的孢粉资料 ,并利用中国第四纪孢粉数据 ,系统开展了中国现代表土孢粉、6kaBP(中全新世 )及 1 8kaBP(末次盛冰期 )的生物群区模拟及重建 ,建立了花粉 气候转换函数和响应面模型 ,并取得了良好的结果 ;冲积物孢粉学和环境考古孢粉学研究 ,也取得了一定成果 ,但研究还有待于深入 ;特征指示种花粉雨研究 ,对古生态环境重建也具有重要的意义。
