Embodiment

[0035] The flowchart of the particle swarm algorithm adopted in the present invention is as figure 1 Show.

[0036] The land use layout intelligent optimization method includes the following steps:

[0037] Step 1. Collect and organize basic data related to land use layout, including basic statistical data and spatial data, basic statistical data such as regional population over the years, demand for various types of land, forest coverage, total area of ​​the region, spatial data such as land use Current status map, evaluation results of various types of suitability, road traffic map, slope map, soil fertility distribution map, and plow layer thickness distribution map. Spatial data needs to be rasterized according to a unified range and grid size, so that the attribute information of each grid unit is corresponding.

[0038] Step 2. Divide the operation unit. According to the grid attribute information sorted out in step 1, multiple grid units with similar attributes and in...

Abstract

The invention relates to an intelligent optimization method for land utilization layout, in particular to an intelligent optimization method for land utilization layout which is applied to optimal configuration of a land utilization space and based on a particle swarm optimization algorithm and belongs to the field of land utilization planning. The intelligent optimization method for the land utilization layout comprises the following steps of firstly collecting and settling statistic data and space data associated with the land utilization layout, secondly selecting a suitable grid pattern spot partition method to determine an algorithm operation unit, thirdly guiding the data into a PSO (particle swarm optimization) model to carry out problem modeling and layout optimizing, and finally generating an optimization result of the land utilization layout. According to the intelligent optimization method for the land utilization layout, the intelligent actions of human can be better simulated in a land utilization decision process so as to improve the reasonability of the land utilization layout; by utilizing the highly effective optimal algorithm, the intelligent optimization method is suitable for the land utilization layout of a large area; and when optimization conditions are changed, the model can dynamically respond in real time to generate a new optimal layout scheme.

Description

technical field [0001] The invention relates to the field of land use planning, in particular to an intelligent optimization method for land use layout. Background technique [0002] Land use layout is the process of implementing various land uses into specific spaces according to the planning indicators issued by superiors and the land use quantity structure determined in combination with the land use demand of the region, which is the basis for the implementation of land use planning. The traditional method of land use layout mostly adopts artificial methods, that is, the natural factors related to land use demand are drawn on the base map according to the principle of land suitability analysis, and the development potential map of various land uses is generated; Restrictions of types and natural conditions are plotted on the map to generate a restriction map of various land use types; the development potential map and restriction map of land use are superimposed to genera...
