Abstract

The invention provides a method and a system for dividing an urban functional area by integrating landscape and social characteristics. Firstly, an application programming interface (API) provided bya network electronic map is utilized to compile a Python network crawler to obtain city landscape data and social media data. Then, through the construction of landscape index, the landscape pattern of the urban functional areas is measured by using the urban landscape data; then, by using social media data and LDA theme model, the socio-economic indicators are established to extract the socio-economic characteristics of urban functional areas; finally, a stochastic forest algorithm is introduced to construct an automatic classification model of urban functional areas and realize urban functional classification. The method and system of the invention are low in cost, high in efficiency and capable of objectively constructing evaluation indexes, and can accurately depict the natural and social characteristics of different urban functions, thereby realizing more refined urban functional area division.

Description

technical field [0001] The invention belongs to the technical field of division of urban functional areas, and in particular relates to a method and system for dividing urban functional areas that integrate landscape and social features. Background technique [0002] Urban functional area refers to the geographical space that can realize the spatial aggregation of natural and social resources and effectively play a specific urban function. With the rapid development of urban construction and social economy, the natural landscape characteristics and socioeconomic characteristics of urban functional areas are becoming more and more prominent. The identification and division of urban functional areas plays an important role in measuring the degree of land use, planning various economic and social functions, and enhancing regional comprehensive competitiveness. The traditional division of urban function zones is mainly based on land use survey data, and the establishment of eva...
