城市物质环境与人口结构耦合的关联分析——以长春市为例

A RELEVANCY ANALYSIS OF THE COUPLING BETWEEN PHYSICAL ENVIRONMENT AND POPULATION STRUCTURE——A Case Study of Changchun

在建立耦合系统评价指标体系的基础上,运用灰色关联分析法构建了城市物质环境与人口结构交互作用的关联度模型和耦合度模型,揭示了长春市物质环境与人口结构耦合的主要因素及耦合关系,并对长春市内部空间单元物质环境与人口结构耦合的分布规律进行了分析。研究结果表明,长春市物质环境与人口结构系统要素耦合的机制错综复杂,而且关系密切;耦合度的空间分布呈现出工业区和旧城区较大,商业区和城市边缘区较小的主要特征,城市内部空间单元可划分为高水平协调耦合、磨合耦合、拮抗耦合和低水平耦合等4种类型。总体而言,城市内部空间单元的拮抗和低水平耦合区域比重较大,城市物质环境与人口结构需要进一步协调。

It is a significant research subject to explore interaction mechanism between urban physical environment and population structure and to promote both of the orderly coupling and coordinated development. These studies are urgent requirement to eliminate the increasingly serious urban social problems and realize the urban harmonious development. Based on previous population censuses and community population survey data of Changchun, the authors establish an evaluation index to the coupling between physical environment and population structure according to the current development and problems of the region. Using methods of qualitative and quantitative analysis as well as grey correlative analysis,the dissertation built a correlation model and a coupling model of the interaction between physical environment and population structure of Changchun. They analyze the major factor and coupling relation between physical and population structure of Changchun, and reveal the distribution rule of the coupling between physical environment and population structure of inner spatial units in Changchun. The results show that the coupling mechanism between physical environment and population structure is impressible ,population structure is closely connected with the physical environment in Changchun;but the coupling degree distribution between physical environment and population structure of Changchun presents a characteristic that industrial district and old city is high and commercial district and urban fringe is low. Inner spatial units of Changchun can be divided into four phase types which are high level harmony, amelioration, conflict and low level coupling. On the whole, the proportion of conflict and low level coupling phase are comparatively large in inner spatial units of Changchun. The authors think that the physical environment and population structure of Changchun need further coordination.
