Abstract: The northern Yanshan mountain region is in the eastern part of the semi agriculture and semi pastoral zone in the north China, where the climate is semi arid and sub humid in the northern temperate zone and the eco environment is very sensitive. In this region, both physical landscape and culture landscape have the transitional characteristics. Based on a great deal of materials of archeology, quaternary geology, paleogeography, and palynology, the author of this paper reconstructed the process of the changes in human landuse forms and analysed the impacts of different environmental conditions on this process in Megathermal. Considering the spatial distribution of archeological cultures, the scale and morphology of settlement, and the composition of production tools, the author found that there was a close relationship between the physical environment and the human’s landuse forms. The following conclusions were suggested: During Climatic Optimum (8 000—5 000aBP), the local Neolithic cultures of zigzag patterns, which include Xinglongwa Culture, Zhaobaogou Culture, and Hongshan Culture, developed continuously in a favorable environment. Most of them had large scales and well arranged sedentary settlements. The Xiaoheyan Culture, which existed around 4 500 aBP, represented the ending of the cultures of zigzag patterns. Both quantity and quality of its settlements decreased considerably, and the agricultural production also descended. These changes of the culture were identical with the environmental changes around 5 000aBP. During 4 000—3 000aBP, there were two kinds of Bronze culture in this region, which were the agricultural Xiajiadian Lower Layer Culture and the pastoral Xiajiadian Upper Layer Culture. The first had a great deal of large scale sedentary settlements and high level agricultural production. The later had less sedentary settlements and lower agricultural production. Such a dramatic contrast between the two distinctive Bronze cultures were mainly caused by the environmental changes around 3 000aBP, that marked the close of Megathermal.
