Increment decline town development boundary delimiting method based on CA model

Abstract

The invention discloses an increment decline town development boundary delimiting method based on a CA model, and the method comprises the following steps: collection of basic data, construction of a database, simulation of increment decline of town based on the CA model, intelligent generation of a town development boundary, and application of the town development boundary. The scientificity and timeliness of the town development boundary demarcation result are realized under the requirement that the territorial space planning background and the town development are changed from extension expansion to increment decline. Through open source data and a CA model algorithm, the urban development boundary is finally delimited, a large amount of manpower and material resources are saved, and the whole planning process is efficient, transparent and stable; according to the invention, the model precision is checked and corrected, and the simulation reliability is realized; the data used by the method are all from real urban data crawled by an open source platform, the real use condition of the land is reflected, the algorithm model can properly adjust the calculation details according to the local demand of the city, and the wide applicability is realized.

Description

technical field [0001] The invention relates to the field of urban planning, in particular to a CA model-based method for delineating urban development boundaries with increments and decrements. Background technique [0002] In reality, there are often contradictions between urban spatial development simulation and spatial pattern optimization, and urban spatial development simulation should gradually change to "incremental and decreasing". Therefore, there is an urgent need to coordinate and integrate urban spatial simulation with the optimization of various spatial patterns such as ecology and agriculture, so that the delineation of urban development boundaries can not only meet the ecological and agricultural bottom line requirements of urban development, but also adapt to the transformation of urban quality improvement . [0003] The existing methods for delineating urban development boundaries mainly include the growth-driven method, the ecological constraint method an...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned methods lack the consideration of the bottom line requirements such as ecological protection red line and basic farmland, and have not yet reflected the current trend of urban development to the incremental and decreasing mode, and there are problems of insufficient timeliness of results and lack of bottom line constraints
