Problems solved by technology

[0005] Aiming at the multi-objective characteristics of site selection for land consolidation projects, which lead to the technical problems of large blindness, large randomness and difficulty in achieving scale benefits in project site selection, the present invention proposes a site selection method for land consolidation projects based on ant colony algorithm. The problem of site selection for land consolidation projects is abstracted into a multi-objective space optimization problem, and the ant colony algorithm is used to solve the multi-objective optimization space problem of site selection for land consolidation projects

specific example

[0110] Step 1. Extract the spatial information required for site selection of land consolidation projects from the second land survey database, land use planning database, land consolidation planning database, and land classification and grading database of a certain county, such as Figure 4 shown. And extract relevant influencing factors and restrictive information from a county's statistical yearbook, agriculture, forestry, transportation and other departments' medium and long-term planning, and integrate with spatial data by adding specific fields, as shown in Table 1 and Table 2.

Abstract

The invention discloses a method for site selection of a land consolidation project based on ant colony optimization algorithm. The method comprises the steps of integrating spatial information data of land utilization and nature and social economy attribute data to form a set of space units for site selection of the land consolidation project; establishing an objective function for maximum added cultivated land potential, an objective function for highest land consolidation suitability and an objective function for continuous space concentrated areas, determining an implementation scale and an added cultivated land ratio as constraint conditions, and constructing an implementation scale constraint condition expression and an added cultivated land ratio constraint condition expression; constructing a model for site selection of the land consolidation project based on ant colony optimization algorithm, establishing a mapping relation between a solving problem and an artificial ant colony, and solving space layout of the land consolidation project; adjusting and optimizing the space layout of the land consolidation project to produce a conceptual drawing for site selection of the land consolidation project. The invention can better coordinate three conflicting optimization goals and can obviously optimize the space layout of the project and improve the social and ecological benefits on the basis of ensuring the economic benefit of the land consolidation.

Description

technical field [0001] The invention relates to the technical field of multi-objective optimization for site selection of land consolidation projects, in particular to a method for site selection of land consolidation projects based on an ant colony algorithm. Background technique [0002] Land consolidation refers to the activities of re-construction and allocation of land resources in a certain area by administrative, economic, legal and technical means according to the overall planning of land use. It can increase the effective cultivated land area, improve land quality, and improve land use efficiency. It can also effectively improve agricultural production, living conditions and ecological environment. Land consolidation is also the product of intensified contradictions between population and land resources in the process of social and economic development. After the founding of the People's Republic of China, the level of urbanization in my country has increased from ...
