摘要:

文章以广州市为例,揭示了大城市边缘区人居环境系统的演变规律:首先,人居环境系统演变过程可以划分为初期、中期、后期三个阶段,各阶段在城市化水平、经济发展状况、基础设施建设、社区形态、景观类型、土地利用等方面都呈现出显著的特征;其次,提出了人居环境容量概念,并借助于GIS空间分析方法,发现边缘区人口密度不断地增加,人居环境容量逐步趋于饱和;第三,大城市边缘区人居环境演变呈现出不均衡的周期性变化。在此基础上,借鉴Verhulst逻辑斯蒂方程与复合生态系统的动力学机制,构建了大城市边缘区人居环境演变的阶段性、生命周期与可持续发展模型。揭示大城市边缘区人居环境系统演变的规律,可为大城市边缘区人居环境系统优化调控提供理论依据,充实人居环境科学理论体系。

Abstract:

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.
