| 摘 要： | The evolvement of a vulnerable ecological region is a dynamic process, which is affected by various factors. 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.

| Abstract: | The evolvement of a vulnerable ecological region is a dynamic process, which is affected by various factors. During the eviolvement
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.
