Abstract

The invention relates to a method for measuring the compactness of urban functional space combined with electronic map interest points. The method combines a grid system with different types of electronic map interest points to extract type grid layers, and calculates the connection index between different types of layers. , and then obtain the connection weight according to the determination of the connection type weights of different types of layers, and finally obtain the urban functional space compactness index by weighting, which realizes the quantitative research on the compactness of urban space and thus more comprehensively reflects the compactness characteristics of urban spatial form; The measurement of urban functional space compactness of electronic map POI improves the correlation between urban compactness index and urban travel time, and can reflect the actual characteristics of urban functional space more scientifically and accurately.

Description

technical field [0001] The invention relates to the intersection of urban geography, geographic information technology and national land space planning technology, in particular to a method for measuring the compactness of urban functional space combined with points of interest in electronic maps. Background technique [0002] The analysis, evaluation and planning technology of urban spatial form is an important branch of urban planning technology. Due to the rapid development of urbanization, the rapid changes in urban spatial form have brought various pressures to urban production, living and ecosystems, and affected the sustainable development of cities. The urban spatial form planning technology attempts to adjust the urban spatial form to cope with the development pressure brought about by urban expansion, and to realize the scientific and orderly development of the city by adjusting the urban spatial layout. Based on the need to curb the disorderly expansion of urban ...
