During the evolvement process, human activities have a decisive effect. The purpose of studying vulnerable ecological region is to control human economic activities and to develop a negative feedback modulation mechanism.This paper established a model of vulnerable ecological region's evolvement by considering four synthetic variables.These synthetic variables are ecological carrying capacity, ecological resilience, economic development intensity, and economic development velocity. Finally, Ongniud Banner and Aohan Banner in North China were taken as study cases to simulate the evolvement processes of vulnerable ecological regions under different conditions of economic development. The results show that human activities have an important influence on the evolvement trend of vulnerable ecological region.展开更多

The aim of the project was, in the perspective of settlernent archaeology, to inquire into the development of social complexity in the two valleys. The data from the lower Banghe River valley show a sharp increase of settlements both in size and in number in the middle Hongshan period. Twenty-three Hongshan sites with a total area of 75.4 ha were found. Moreover, their variety in grade suggests considerable social complexity. In the upper Laohushan River valley, almost no residential sites were recorded except for seven sacrificial sites. This, following the discovery of the Niuheliang ritual complex, again demonstrates the existence of exclusive sacred places separated from everyday secular life.展开更多
