A Population Initialization Method for Intelligent Optimization of Land Use Spatial Layout

Abstract

A population initialization method for intelligent optimization of land use spatial layout, including making a difference between the number structure of land use in the regional planning year and the number structure of the current situation of regional land use, and obtaining the planning schemes of various types of land in the region and the pixels of the current area The number difference, get the list A of the land type that needs to be transferred into the pixel and the list D of the land type that needs to be transferred out; generate a random position i on the individual to get the neighborhood P; A set Y is obtained from multiple land types appearing in the list A at the same time, and the land type with the largest number of pixels in the obtained set Y is L; the land type change operation is performed on all pixels in the neighborhood P; until the lists A and D are both If it is empty, the initialization process ends and the initial individual is output. The invention improves the generation quality and efficiency of the initial individuals, supports the efficient implementation of the land resource spatial layout optimization scheme of the land use planning, and provides an important guarantee for realizing the rational, efficient and sustainable utilization of the land resources.

Description

technical field [0001] The invention belongs to the technical field of optimal configuration of land use space layout, in particular to a population initialization method for intelligent optimization of land use space layout. Background technique [0002] The spatial layout optimization of land use is an important part of land use planning. Its core content is to scientifically and rationally optimize the land use quantity according to the natural attributes (position, shape, soil conditions, etc.) of the regional land. Configure the layout of each type of land in the regional space. Then improve the overall suitability and space compactness of regional land use, making the spatial layout of land use more conducive to ecological environment protection and production and operation management. Therefore, in essence, the spatial layout optimization problem of land use is a typical combinatorial optimization problem with constraints. [0003] The solution to the optimization p...

Problems solved by technology

The method of randomly generating initial solutions is not necessarily suitable for the optimization of land use space layout. The specific performance is as follows: (1) The quality of the initial solution generated by random search is usually poor, and the quality of the solution set obtained after multiple iterations It is not even as good as the current situation of regional land use spatial layout; (2) The initial solution generated by random search method is likely to violate the suitability constraints of land use, for example, the use of a piece of land is allocated to its unsuitable use: the river water surface configured as woodland etc.
