Land Use Quantitative Structure Optimization Based on NSGA-II——A Case Study of Dinghai District in Zhoushan City

The optimization of land use quantitative structure is a typical problem of multi-objective optimization, and is also the main problem of land use plan. An optimization model of land use quantitative structure based on NSGA-II was set up in this paper through the introduction of non-dominated sorting genetic algorithm with the elite strategy. On the basis of referring to NSGA-II source code offered by the Kanpur hereditary algorithm laboratory,and carrying on the secondary development of the procedure by using C/C++ language,a series of Pareto solutions were obtained and Pareto solution set was constructed. Finally,weights were used to express decision-making wills approximately,and comprehensive benefit value was calculated to realize decision-making under all kinds of wills. The result indicates that the model can solve the problem of land use quantitative structure optimization effectively.
