Population initialization method for intelligent land utilization space layout optimization

Abstract

The invention provides a population initialization method for intelligent land utilization space layout optimization. The population initialization method includes the steps that the difference value between a land utilization number structure of a regional planning year and a regional land utilization present situation number structure is acquired to further acquire the difference value of all kinds of land utilization planning schemes in a region and the number of pixels of the present-situation area, and a list A of land types into which pixels need to be called and a list D of land types out of which pixels need to be called are acquired; a random position i is generated on an individual to acquire a neighborhood P; statistics of a plurality of kinds of land types existing in the neighborhood P and the list A at the same time is carried out to acquire a set Y, and a land type L with the largest number of pixels is acquired from the set Y; land type changing operation is carried out on all pixels of the neighborhood P; the initialization process is over and the initialized individual is output until both the list A and the list D are empty. The method improves initialized individual generation quality and efficiency, achieves efficient execution of land resource space layout optimization schemes in land utilization planning, and accordingly provides important guarantees for reasonable, efficient and sustainable utilization of 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.
