Fine population analysis unit division method based on urban form and population convergence mode

Abstract

The invention discloses a fine population analysis unit division method based on an urban form and a population convergence mode, and the method comprises the following steps: S1, considering the spatial structure of the urban and the fine-grained demand of population analysis, facing the functional heterogeneity of a micro-scale population activity area, fitting the natural form of the urban, and dividing basic analysis units; s2, constructing a population convergence preference model by considering spatial distribution characteristics of urban population flow in local convergence and long-term stable characteristics depending on dynamic changes of entrances and exits; and S3, according to the microstructure elements in the basic analysis unit, dividing an FPAZ (Fine Population Analysis Zone) suitable for expressing and analyzing population distribution and change characteristics. According to the method, the FPAZ suitable for expressing the population distribution and change characteristics is divided based on the urban form elements and the population convergence preference model by considering the urban form characteristics and the population convergence mode, analysis and mining of the population distribution and change spatio-temporal mode are facilitated, and fine management of urban population is further supported.

Description

technical field [0001] This application belongs to the field of intelligent computing of urban geography, and designs a refined population analysis unit division method based on urban form and population aggregation mode. Background technique [0002] Population analysis unit is the basic spatial unit for urban population analysis spatio-temporal operation, rule mining and visualization of analysis results. Static population distribution or dynamic population change information is displayed through the population analysis unit, and time-space analysis is carried out based on the population analysis unit. The attributes of the population analysis unit, such as shape, area size, and spatial continuity, directly determine the fineness of population information expression and population analysis. Result accuracy. Therefore, an appropriate population analysis unit division method is crucial for effectively expressing information on urban population activities, analyzing the spat...

Problems solved by technology

[0005] In general, the current population analysis unit division methods are mainly driven by research data and application needs, and lack the division method that considers the human unit from the perspective of population distribution and change characteristic expression and analysis accuracy

Especially at the micro scale, the results of the division of these three types of population analysis units tend to have different problems from urban forms, low continuity of spatial units, and insufficient spatial resolution, which lead to inaccurate expression of population information and poor scene versatility , unable to support fine and accurate urban population analysis and the application of analysis results for a long time
