Exploration on Ant Colony Optimization for Optimizing Land Use Spatial Allocation

Abstract

The purpose of optimizing the allocation of land use (LU) space is to enable effective utilization of land resources in various regions, in order to maximize the economic and social benefits of limited land area. The upper reaches (UR) of the Yellow River are important agricultural production bases and ecological barriers in China, and optimizing land space is of great significance for promoting agricultural development and protecting the ecological environment. Therefore, the optimization method based on ant colony optimization (ACO), as a new type of optimization algorithm, has strong adaptability, robustness, and global search ability, which can effectively solve the problem of LU spatial optimization configuration. This article determined the definition and constraints of land issues, and set relevant parameters. The steps of the ACO were analyzed, and the results of the algorithm were analyzed and evaluated. The LU situation in the UR of the Yellow River was analyzed using survey methods and statistical analysis. The results showed that the patch density index before and after optimization in various regions was generally small, with the index values of forest land and construction land being 0.1142 and 0.2975, respectively.
