Abstract

The invention discloses a city expansion boundary prediction method based on space syntax; the method comprises the following steps: 1, drafting a segment map and extracting a built up area boundary; 2, setting up a fixed grid unit; 3, calculating space syntax form analysis variables, and assigning values to the grid; 4, calculating distances from each mesh to the built up area boundary; 5, setting up a multivariate linear regression model and examining the model; 6, predicting a city expansion boundary. The method forms the built up area boundary and the space syntax form analysis variables quantification model, and applies the model in the city expansion boundary prediction, thus providing novel thinking for city program decision and city boundary problem research.

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...
