Embodiment Construction

[0069] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0070] Such as figure 1 As shown in , a land resource spatial optimization allocation method applied to the preparation of land use planning includes the following steps:

[0071] S1. Divide the land in the area to be planned into several grids, randomly assign a land use type to each grid, generate a land resource space configuration plan as an initial solution, and repeat step (1) n times to obtain n initial untie;

[0072] S2. Calculating the size of the comprehensive target value of the aforementioned n initial solutions, including the following steps:

[0073] Step 1: Define two types of objectives for land resource allocation, namely direct objectives and spatial objectives;

[0074] The direct target refers to the direct benefits generated by land use, including economic benefits, ecological benefits, and spatial suitability; the spatial targe...

Abstract

The optimal spatial allocation method of land resources applied to land use planning takes into overall account the direct and spatial objectives of land use, defines the relevant constraints from the perspective of space, and achieves the optimal spatial allocation of the land resource through the search of multi-objective genetic algorithm. The method fully considers the direct and spatial objectives of land use, defines the relevant constraints from the perspective of space, and achieves a spatial layout ideal for land use through the search of multi-objective genetic algorithm, which can provide technical support for the preparation of urban planning, land planning and ecological protection planning.

Description

technical field [0001] The present invention is applied in fields such as land resource management, urban planning, ecological environment protection, and it is a kind of land resource space optimal allocation method in the process of land use planning, urban planning compilation, and this method is based on the spatial multi-objective genetic algorithm ( GA), and provides an interactive platform for decision makers, who can determine the final ideal land use spatial layout through multiple interactions. Background technique [0002] At present, the relevant land planning units, whether government research institutions or market enterprises, ignore the process of space optimization when compiling land use planning, and only focus on quantity allocation, without fully considering how to allocate a certain amount of land to space, that is, space There is no certain technical method to support the compilation of planning drawings, so its rationality and scientificity need to be...
