摘要
本文采用粒子群算法构建了土地利用优化配置模型,在分析了兰州市七里河区近19年来土地利用现状和景观格局的基础上,指出了土地利用过程中存在的特点,运用粒子群算法算法得出了兰州市七里河区2014年土地利用优化配置结果,并与2014年土地利用/覆盖分类结果进行了精度分析与景观格局分析,结果表明此算法有效的优化了七里河区土地。
In this paper,particle swarm optimization algorithm was applied to construct a land use allocation model.Based on the analysis of nearly 19 years' land use and landscape pattern on Qilihe District of Lanzhou,the characteristics of land use were pointed out,and the optimal allocation results of land use in Qilihe District in 2014 were obtained by adopting particle swarm optimization algorithm,and compared with the 2014 land use / cover classification results by applying accuracy analysis and landscape pattern analysis.The results showed that the algorithm effectively optimized the land use of Qilihe District.
