| Land is the natural geographical complex which over the earth’s surface within a certain space, its interior composed by various organic materials and material,and affected by the impact from the different aspects of nature. Optimization of land use structure, which uses the principle of system optimization and regard land as a complex decision-making system to study, is the system theory applies in the land science. With the deepening of the research, the mathematical model,which the representation of technical methods, more and more applied in the land study, makes the land study developed from qualitative analysis to quantitative evaluation. Model optimization has been the essential technical method in land science. In the study course of this project, in order to make the more profound explore, and ensure the rationality of solution, the author views from aspect of society, economy and ecosystem, rational distributes land use structure in a certain time and space, make the land system to maximized efficiency.The land use structure, which good or not, is very important for a certain period of the regional economic and social development, therefor it has been the focus of academic circles. Today, which more people and less land and contradiction of land supply and demand is obvious, uses advanced technical method, combines the double affected system of market regulation and macroeconomic regulation and control, reasonable distributes regional land resource, ensure the development of society and economy in the pace of reasonable, sustainable and stable, has been the topic which focused by the all. Through rational allocation of land, optimizing land use structure, achieving the optimal input-output ratio, achieving sustainable utilization of land resources, is the inevitable development of scientific development.Ant colony algorithm is a kind of simulation optimization algorithm, which can deal with all kinds of problems by means of simulation, and to a large extent,to ensure the optimality of the results. The ant colony algorithm is introducedto optimize the land use structure In this paper, it is a bold attempt. Through the construction of land use structure optimization mathematical model, is solved by ant colony algorithm, optimization to obtain the best method, aims to explore the reasonable land use structure, the optimization results can meet the greatest degree of relevant departments of economic requirements, concurrently at the same time social and ecological benefits, to promote regional economic development,can to people’s daily life to provide convenient, maintain the ecological balance of the environment, so as to ensure that the land can be the most efficient use.In this paper, we choose Cenxi City as the research area, and use the ant colony algorithm to optimize the regional land use structure.First of all, describe the relevant concept from the theoretical aspects. The related theory of land use structure optimization, ant colony algorithm and related theory of mathematical model were designed to reveal the relationship between the three, which lays a theoretical foundation for the following analysis.Second, regard Cenxi city as the study area, first for the study of regional land utilization analysis, reveal the land use structure, and the trend, analysis of the characteristics and problems of the land use, and combining the regional construction land use structure optimization mathematical model, in MATLAB software based on ant colony algorithm, so as to obtain land use structure optimization program.Finally, the optimization results are analyzed, and the countermeasures are discussed from the point of view of optimization. At the same time, the content of the full text is summarized, which can provide reference for the maximum benefit of the latter. |
