Embodiment Construction

[0035] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0036] The present invention provides a kind of calculation method based on city function mixing degree, and it comprises the following steps:

[0037] The system acquires POI datasets in batches, and classifies urban functions according to the type information in POI datasets;

[0038] The system draws the urban road line layer data, and extracts the center point of each road as the measurement unit of urban function mixing;

[0039] The system extracts the adjacent blocks of the road where each measurement unit is located, and constructs the urban function mixing degree measurement index of each measurement unit;

[0040] The system establishes a function mixing degree calculation model, and calculates the urban function mixing degree for each measurement unit.

[0041] As an improvement of this techni...

Abstract

The invention discloses a measuring method and system based on urban function mixing degree, which includes the following steps: acquiring a POI data set, and classifying urban functions according totype information in the POI data set; drawing urban road line layer data, and extracting each road center point as a measuring unit of urban function mixing degree; extracting adjacent blocks of the road where each calculation unit is located, and constructing an urban function mixture degree calculation index of each calculation unit; establishing the function mixture degree calculation model, and calculates the urban function mixture degree for each calculation unit. A calculation system based on urban function mixture degree, which comprises: a POI data set acquisition module, a calculationunit division module, a calculation index construction module, and a calculation model establishment module. According to the measuring method and system based on urban function mixing degree, deep research is carried out on the mixed functional area, meanwhile, the influence of the street on the urban function area is considered, therefore the invention is more practical, the calculation efficiency is improved, and can be widely applied to the field of urban planning.

Description

technical field [0001] The invention relates to the field of urban planning, in particular to a method and system for measuring and calculating based on the mixed degree of urban functions. Background technique [0002] The mixed degree of urban functions refers to the comprehensive composition of urban functional types that are closely related to residents' lives within a specific city. Its measurement and analysis results have important practical significance in terms of urban resident traffic, land use improvement, urban planning layout, etc., and can provide important data support for the analysis of urban traffic conditions, travel efficiency, land use evaluation calculations, and urban layout optimization analysis. . [0003] At present, the calculation of urban functional mix is ​​mainly done through on-site surveys, questionnaire surveys, remote sensing image interpretation and other means. This method has problems such as time-consuming and laborious data acquisiti...
