传统数学方法难以有效解决土地利用结构多目标优化问题,针对土地利用结构优化的多目标性和遗传算法在多目标优化求解方面的优势,以经济效益和生态效益为目标函数建立土地利用结构优化数学模型,采用遗传算法进行模型求解.以重庆市合川区为例详细介绍了具体应用过程,得出了4个可行方案,对方案进行论证择优,选出满意的最佳方案,证明采用遗传算法进行土地利用结构多目标优化求解是科学可行的.%It is difficult for the traditional mathematical methods to deal with land use structure multi-objective optimization. Because land use structure optimization is generally multi-objective and genetics algorithm has great advantage for multi-objective optimization, in this paper, the mathematics model is established for land use structure optimization with the economic benefits and ecological benefits as the target functions, and genetics algorithm is used to search the solution for the model. The land use structure optimization for Hechuan District of Chongqing Municipality is taken as a case study, and the detailed procedures are explained. Four feasible solutions are found with this method and the most satisfactory one is selected from them after demonstration. The genetics algorithm is proved to be scientific and feasible for solving the multi-objective optimization of land use structure.
