Embodiment

[0157] In this embodiment, Zhejiang Province is taken as an example to conduct regional urban spatial correlation effect (UCI) detection (2010-2015).

[0158] Such as figure 2 As shown, when UCI>0, it indicates that the development of regional cities is in the stage of mutual promotion (dotted lines of different thickness represent this positive promotion effect, and its thickness indicates the strength and weakness of the effect in space); UCI<0 When , it indicates that the development of regional cities is in the stage of growth and inhibition (the gray line expresses this effect).

[0159]From 2010 to 2015, Wenzhou was in a downward stage of development. Compared with other cities in the region, there was an obvious relative decline in development, and it entered the suppression end of the growth and suppression stage; in addition, Quzhou, Lishui, and Taizhou were also at the States of growth versus suppression. However, other cities in the region are in a pattern of pos...

Abstract

The invention relates to a quantification method for regional city system evolution and space effect. The quantification method comprises the following steps: step 1, collecting related data of a cityto be measured; step 2, constructing regional city system space-time evolution (CS); 3, expressing the model of the urban system (cs); step 4, constructing a multivariable-spatial distance network (ND-M); step 5, constructing and expressing urban system components; and step 6, determining the spatial correlation effect of the urban system. Aiming at the problems of regional city development state, city element evolution and growth, inter-city mutual influence mode and the like, ina city system space-time evolution method and system, systematic and spatial thinking modes are creatively combined, and connection modes and connection characteristics existing among regional cities in the development process are quantitatively expressed by establishing a mathematical model.

Description

technical field [0001] The invention belongs to the technical field of urban planning, and in particular relates to a quantitative method and system for regional urban system evolution and spatial effects. Background technique [0002] The basic idea of ​​system theory is to regard the object of research and processing as a whole system. System theory is to study the structure, characteristics, behavior, dynamics, principles, laws and connections between systems, and to summarize them mathematically. The main task of system theory is to study the system as a whole and the interrelationships of the elements that make up the system as a whole from the perspective of the whole. [0003] System evolution refers to the process of evolution and development of the system under the interaction of various components. System evolution has both order and disorder characteristics, and the two alternate and transform each other. The development trend of the system in the state of orde...
