The evolvement rules of human settlements system on metropolis fringe:A case study of Guangzhou
大城市边缘区人居环境系统演变规律——以广州市为例

Human settlements are the base for human survival and development,the most consanguineous and material geographic space between human and environment.With the urbanization in China,the emphasis on human building settlements is transferred to fringe and the importance of fringe human settlements becomes more obvious.The evolvement of human settlements in metropolis fringe is the result of different kinds of forces in and out of human settlements during the man-nature interaction and follows some rules.Taking Guangzhou as the case,some evolvement rules are disclosed.Firstly,human settlements system evolvement is separated into three phases,i.e.initial phase,metaphase and anaphase with prominent characteristics of urbanization,economy,infrastructure,community,landscape and landuse.Secondly,the conception of human settlements capacity is put forward and with the method of GIS,it is found out that the population density increases and the human settlements capacity approaches to saturation.Thirdly,the evolvement of metropolis fringe human settlements develops with unbalanced periodicity.On the basis of it,using the Verhulst Logistic Equation and Complex Ecosystem Dynamics Mechanism for reference,the phase,life cycle and the sustainable development model of metropolis fringe human settlements are established.The study on the evolvement rules of human settlements in metropolis fringe is of great theoretical and practical significance by disclosing the rules of human settlements development.It tries to construct the elementary theoretical frame of human settlements in metropolis fringe,enriching the theoretical system of human settlements sciences,and guiding the optimization and regulation practices of human settlements in metropolis fringe.
