According to the method, the accuracy of city expansion simulation can be improved.

Description

[0001] technology neighborhood [0002] The invention relates to the field of computer technology, in particular to a method and device for simulating urban three-dimensional space expansion. Background technique [0003] With the acceleration of urbanization, cities are facing enormous pressure on urban space demand from economic development and population growth. Early urban sprawl by developing low-rise buildings in a two-dimensional space has long been considered harmful to the natural environment, resulting in a shortage of land resources and inefficient use of urban space. In recent years, the expansion of urban vertical space has been strengthened, and many cities have entered the stage of vertical space development. By excavating and using the vertical space of the city, the land use efficiency within the city can be improved, and the land use pressure in the process of urban development can be alleviated. In addition, as the development of urban space transitions f...

Problems solved by technology

In addition, as the development of urban space transitions from two-dimensional to three-dimensional, the spatial form, structure, function and process of the city become more complicated.

Analyzing the urban expansion in the horizontal direction only from a two-dimensional perspective cannot give a more accurate and complete understanding of the process and law of urban spatial expansion.

The existing technology is relatively rich in urban two-dimensional space simulation methods, and has many practical applications, but it can only simulate urban land use changes on a two-dimensional plane, ignoring the impact of urban building heights and three-dimensional space capacity on urban three-dimensional space. The effect of sprawl, so the simulation of urban sprawl is not accurate enough
