【摘要】：土地利用优化配置是促进土地可持续发展的重要举措,然而现有研究缺乏有效求解土地利用优化配置模型的新型混合式智能优化算法。本文结合蚁群算法和混沌模型,形成混沌蚁群优化(Chaos Ant Colony Optimization,CACO)算法,并以广州市增城区为研究区,对土地利用现状进行优化配置;然后在数量结构、目标函数值、空间布局等方面将优化结果与土地现状及标准蚁群算法优化结果进行对比分析。结果表明:(1)CACO算法能在满足多种约束条件下,有效解决多目标土地利用优化配置问题;(2)与标准蚁群算法相比,CACO算法能增加土地利用的经济效益7.18亿元、生态效益0.33亿元、社会效益1.13%,同时降低地类转换成本1.15%;(3)CACO算法能使土地利用现状空间分布多样性和均匀性的下降控制在1.30%以内,同时缩减地块数量8.86%,并使平均斑块大小增加9.77%,从而提升土地集约利用水平,更合理地配置各现状地类的空间分布,为研究区土地利用的科学规划与决策提供支持。
[Abstract]:The optimal allocation of land use is an important measure to promote the sustainable development of land, but the existing research lacks the optimal allocation model of hybrid intelligent optimization algorithm for effective land use. Based on ant colony algorithm and chaos model, chaos ant colony optimization (Chaos Ant Colony Optimization CACO) algorithm, and takes Zengcheng District of Guangzhou city as the study area. To optimize the allocation of land use status; then the quantity structure, the value of the objective function, the space layout optimization results and the current situation of land and the standard ant colony algorithm optimization results were compared and analyzed. The results showed that: (1) CACO algorithm can satisfy various constraints, effectively solve the multi-objective optimal allocation of land use; (2) compared with the standard ant colony algorithm, CACO algorithm can increase the economic benefits of land use ecological benefit 718 million yuan, 33 million yuan, 1.13% social benefits, at the same time drop The low class conversion costs 1.15%; (3) CACO algorithm can make the distribution of land is decreasing diversity and uniformity of space utilization is controlled within 1.30%, while reducing the number of plots in 8.86%, and the average patch size increased 9.77%, so as to improve the level of land intensive use, more reasonable allocation of each kind of space distribution situation, provide support for the scientific decision and planning of land use in the study area.
