Abstract: In the previous paper authors found the vegetational and climatic changes in the past 30,000–10,000 years in Beijing. This paper is based on the informations of the sporo-pollen assemblages obtained from the Gaolizang, Dawangzhang, Yinjiahe, Xiwu- tiyng etc. with drilling cores in the vicinity of Beijing. About 12,000–10,000 years ago deciduous broad-leaved trees were flourishing in Beijing. At that time the climate was warm and rather wet. 10,000–8,000 years ago, the herbaceous plants, such as Artemisia, Compositae were flourishing in plain of Beijing and mountainous region was dominant in subalpine conifer forest, consisting of Pinus, Picea and Abies, According to the needle-leaved forest increasing at that time we think about 9,000 B. P. that climate was cool and wetter. In the past 8,000–6,000 years, needle-leaved and deciduous broad-leaved mixed forest, consisting of Pinus, Quercus and Betula thrived under a warm and wetter climate, the bogs were better developed in plain. During 6,000–2,000 years, in general review on the sporopollen assemblages of the Beijing we think that the climate was warm, especial about 5,000 years ago, the flora was mainly composed of deciduous broad-leaved trees, such as Ulmus, Quercus, Morus and Betula. But during 5,600 years ago or so, spruce-fir forest became predominant in the low land and the plain of Beijing again. At that time the annual mean temperature was lower than that of the present. It was corresponed to new glacial period. The flora mainly composed of Pinus was obviously reduced since 2,000 years. The glassland even increased in Beijing.
