Abstract

The invention discloses a method for predicting the boundary of urban expansion based on space syntax, comprising the following steps: 1) drawing a segment map (Segment Map) and extracting the boundary of built-up areas; 2) establishing a fixed grid unit; 3) calculating the form of space syntax Analyze variables and assign values ​​to the grid; 4) Calculate the distance from each grid to the boundary of the built-up area; 5) Establish and test the multiple linear regression model; 6) Predict the boundary of urban expansion. The method of the invention constructs a quantitative model between the built-up area boundary and the space syntax morphological analysis variables, and applies the above model to the prediction of the urban expansion boundary, which can provide new ideas for urban planning decision-making and urban boundary research to a certain extent.

Description

technical field [0001] The invention relates to a method for predicting the boundary of urban expansion, in particular to a method for predicting the boundary of urban expansion based on space syntax. Background technique [0002] my country's urbanization process is accelerating, how to effectively control urban growth is an important topic of urban development research. Since the urban system is affected by many factors, and its internal spatial activities are complex and changeable, previous studies on cities focused on analyzing economic and social factors, and believed that the shape and mode of urban space are only their projections on the region, and they are economic and social processes. Shaped the physical city. Most of the models for predicting expansion boundaries based on this urban analysis method consider many factors and are relatively complex, such as cellular automata model, SLEUTH model, CLUE-S model, binary logistic regression model, multivariate logisti...
