摘要
对人地关系地域系统结构耦合的定量研究是认识人地关系要素因果反馈联系,揭示系统内在动力机制和构建人地系统定量模型的基础。该文在建立要素结构和区域发展系统耦合评价指标的基础上,运用灰色关联分析方法构建出要素结构和区域发展交互作用的关联度模型和耦合度模型,定量揭示出影响关中平原人地系统发展的主要因素及其作用强度。影响区域发展的主要因素有人口规模及其在空间集聚的态势、对资源占有和消耗量、发展对环境的胁迫及地域区位条件的优劣方面,而传统要素的作用下降;根据耦合度模型计算结果,从空间上表现出以中心城市为核心的圈层结构,结合发展水平指数,将关中平原44个县市区划分为协调型、拮抗型、磨合型和低水平耦合型4种类型。总体上看,关中平原人地系统要素结构和区域发展以拮抗类耦合型为主。
Quantitative study on man earth areal system coupling structure is the foundation which is to understand cause and effect feedback relationship, reveal inherent evolutive mechanism and build quantitative models of man earth areal system. Based on the panel and serial statistical data, an evaluation index of man-earth areal system coupling between factor structure and region development of Guanzhong plain is analyzed. Using methods of qualitative and quantitative analysis, and grey correlative analysis, the article built a correlation model and a coupling model of the interaction between factor structure and region devel opment of Guanzhong plain. It analyzed man-earth areal system coupling between factor structure and re gion development of Guanzhong plain, the static space distribution of the coupling of counties in Guanzhong plain in 2005, the dynamic contrast of distribution in 2005 in Inner Mongolia. The results show that the coupling mechanism between factor structure and region development is sophisticated, factor structure is closely connected with the development of regional economy in Guanzhong plain; but the cou piing distribution degree between factor structure and region development of Guanzhong plain presents an inverse law to factor structure. Guanzhong plain can be divided into four types： harmony, amelioration, conflict and low level coupling. In general, amelioration predominates isdominan, reaching 60%, followed by low-level coupling.
