Problems solved by technology

Boolean constraints have a wide range of applications because they reflect the coerciveness of laws and regulations. However, the design of 0-1 constraints is too absolute and simplistic, ignoring the elastic characteristics of human and economic factors such as government policies in geographical space distribution, and also The spatial gradient characteristics of regional natural background elements are ignored, and the complexity of constraints such as government policies and geographical environment requires the establishment of a more flexible constraint mechanism

Abstract

The invention relates to an urban cellular automaton scene simulation method, a terminal device and a storage medium. The method comprises the following steps of: S100, collecting an ecological environment data of a research area; S200, performing ecological environment evaluation according to the collected ecological environment data, and obtaining an ecological index as an ecological constraintfactor; S300, establishing an ecological constraint based on an ordered weighted average in the urban cellular automaton according to the ecological constraint factor; and S400, establishing a urban cellular automaton model based on a logistic regression according to the ecological constraint, so as to simulate a city space dynamic evolution process. The urban cellular automaton scene simulation method couples an urban model of a binary logistic regression, the ordered weighted average and the cellular automaton, which is beneficial to identify the region with the most contradiction and stressbetween the urban development and the ecological constraints and give a reasonable solution, and is also beneficial to find trade-offs between the development and the protection for urban managementdepartments.

Description

technical field [0001] The invention relates to the technical field of urban dynamic simulation, in particular to an urban cellular automaton scene simulation method, terminal equipment and a storage medium. Background technique [0002] The rising rate of urbanization is continuously driven by complex socioeconomic factors such as population migration, factor agglomeration, technological progress, and policy incentives. In 2050, a whopping 67.1% of the world's population is expected to live in urban areas, compared to just 3% of the world's urban population in 1800. Understanding the evolution mechanism and process of urban spatial form will help to control or alleviate a series of natural, social and environmental problems caused by over-urbanization, such as traffic congestion, sharp decline of farmland, and environmental pollution. [0003] In the past 30 years, urban cellular automata have been widely used in urban dynamic simulation. The constraint mechanism is a key ...
