Abstract

The invention relates to a city function space compactness measuring method combining electronic map interest points. According to the method, a grid system is combined with different types of electronic map interest points to extract type grid layers; the relation index between different types of layers is calculated, the relation weight is solved according to the judgment of the relation type weight of different types of layers, and finally weighting is performed to obtain the urban function space compactness index, thereby realizing the quantitative research of the urban space compactness,and more comprehensively reflecting the compactness characteristic of the urban space form. By combining the urban function space compactness measurement of the electronic map interest points, the correlation between the urban compactness index and the urban travel time is improved, and the actual characteristics of the urban function space can be reflected more scientifically and accurately.

Description

technical field [0001] The invention relates to the interdisciplinary fields of urban geography, geographic information technology and land space planning technology, and in particular relates to a method for measuring the compactness of urban functional space combined with points of interest on an electronic map. 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 urban spatial form has changed rapidly, which has brought various pressures to urban production, life and ecological systems, and affected the sustainable development of cities. Urban spatial form planning technology attempts to respond to the development pressure brought about by urban expansion through the adjustment of urban spatial form, and realize the scientific and orderly development of cities by adjusting the urban spatial layout. Based on the need to cur...
