中文摘要：

转变从对旧石器时代在 10000 一 BP 附近过时是人的历史上的一个重要事件。我们在 Donghulin 从一个早过时的地点基于样品在 Zhaitang 区域(北京) 分析了 paleoenvironment。这个地点被认为在这个区域表明旧石器时代过时的转变。这个地点与几架人的骨骼产出埋葬，作为 Donghulin 人知道。我们在 Donghulin 区域进行了 geomorphological 和第四级的地质的调查，并且也分析了沉积和花粉，使我们能讨论本地人的生活环境。Donghulin 人主要从 111009600 cal 生活了 BP；温暖跟随更年轻的 Dryas 的一个时期。气候好，陆地被干燥适度的草地盖住，并且以后，弄湿适度的草地大草原。Donghulin 人通常住在泛滥平原；这扁平、温暖、湿，与为有利生活环境的丰富的植物和动物。我们的研究帮助在 10000 一 BP 附近在北京区域重建人的生活环境，并且在旧石器时代过时的转变期间在北方中国关于环境背景理解更多。

英文摘要：

The transition from Paleolithic to Neolithic around 10000 a BP was a significant event in human history. We have analyzed the paleoenvironment in the Zhaitang area （Beijing） based on samples from an early Neolithic site at Donghulin. This site is considered to demonstrate the Paleolithic-Neolithic transition in this area. The site yielded burials with several human skeletons, known as ＂Donghulin man＂. We conducted a geomorphological and quaternary geological investigation in the Donghulin area, and also analyzed sediments and pollen, enabling us to discuss the living environment of the local people. Donghulin man lived mainly from 11100-9600 cal a BP; a period of warming following the Younger Dryas. The climate was good, the land was covered by dry temperate grassland, and later, wet temperate meadow steppe. ＂Donghulin man＂ usually inhabited the floodplain; this was flat, warm, and wet, with abundant plants and animals for a favorable living environment. Our research helps to rebuild the living en- vironment of humans in the Beijing area around 10000 a BP, and to understand more about the environmental setting in north China during the Paleolithic-Neolithic transition.
