A decision-making method for the construction of urban public service facilities that affects population density

Abstract

The invention discloses a decision-making method for the construction of urban public service facilities that affects population density. The urban space is divided into square geographic grid units with the same side length. On the basis of the urban population spatial distribution data, all types of interest point densities, different The density of interest points of functional type and the mixing degree of functional types of interest points are three parameter indicators that reflect the current development level of urban public service facilities, and a linear regression analysis between different indicators is carried out; the parameter indicators that pass the regression model test are further quantified Regression analysis, constructing the correlation and influence process between the population distribution data in the geographic grid unit and the public service facility indicators, and comprehensively judging the impact of public service facilities on regions with different population development stages. This method accurately reflects the types of public service facilities that should be prioritized in cities at different levels of population development, so as to improve the efficiency of population density and optimize the use efficiency of public service facilities.

Description

technical field

[0001] The invention relates to the technical fields of urban planning, infrastructure, and public services, in particular to a decision-making method for urban public service facility construction that affects population density. Background technique

[0002] The uneven layout or low efficiency of public service facilities has become a prominent social problem in recent years. On the basis of emphasizing the balance of public service resources, the investment and construction of urban public service facilities must be moderately advanced to avoid construction lag and blindness. Therefore, scientificity and rationality are important prerequisites for urban infrastructure development planning. However, the existing public service facilities have large investment but low output and low efficiency, and there are phenomena of idleness, low efficiency and insufficient area, which are not conducive to the increase of regional population. Especially in the process ...
