Embodiment 1

[0097] Example 1: Take the old urban area of ​​a certain city as the research object for practice, with a total area of ​​about 43.3 square kilometers. This area includes the central area of ​​the city and many commercial and cultural facilities, with rich crowd activities, which is a better way to predict urban vitality. Good choice.

[0098] like figure 1 As shown, this implementation case provides a method for predicting the vitality of urban blocks, which specifically includes the following steps:

[0099] 1. Obtain OSM traffic road network data, divide the study area into several blocks, and use the area within the block boundary as the basic unit. There are 151 basic units in this implementation case.

[0100] 2. Obtain the Baidu heat map data. The Baidu heat map data obtained in this implementation case comes from the average raster data of a day on October 21, 2021, and it is coordinately registered, and the registered heat map is the fourth band Band4 data Convert t...

Abstract

The invention discloses an urban block vitality prediction method, a storage medium and a terminal, and belongs to the technical field of urban planning. A city block vitality prediction method comprises the following steps: obtaining vector boundaries of blocks in a to-be-detected area from road network data, and taking areas in the boundaries as basic units; obtaining built environment data of blocks in the to-be-detected area from the basic units as independent variables; acquiring crowd activity intensity data of the blocks in the to-be-detected area, and quantifying the crowd activity intensity data to acquire an urban vitality value; matching the basic units, the block built environment data and the crowd activity intensity data to construct a training database; adopting a GBDT algorithm to train the training database to obtain an urban block vitality prediction model; and predicting the block vitality of the to-be-detected area based on the city block vitality prediction model. According to the method, the vitality of the city constructed in the future is accurately predicted through the constructed environment indexes of the blocks, so that a basis is provided for a planning and design strategy.

Description

technical field [0001] The invention relates to the technical field of urban planning, in particular to a method for predicting the vitality of urban blocks, a storage medium and a terminal. Background technique [0002] Urban vitality is the ability of a living environment to stimulate interaction between people, and it is also the most basic element to achieve the quality of urban life. Scholars and practitioners have therefore explored urban vitality as an element of urban development and planning since the 1950s. Predicting urban vitality is of great significance to urban development and construction. It can help urban planners and managers to quantitatively evaluate the design strategies and development patterns of a planned area or a regeneration area. However, most studies and applications focus on using multi-source data to measure urban vitality and its relationship with space, society and other elements, and rarely involve related technical methods for urban vital...
