基于正余弦算法的城市土地利用空间的优化配置
|
摘要
针对环境友好程度和总体资源节约条件下,实现土地空间的最优化利用和为城市土地规划提供参考和决策依据。本文在传统的RLUAM数学模型的基础上,提出一种基于正余弦算法优化RLUAM模型的城市土地利用空间的最优化配置的数学模型。为了验证其有效性,选择上海市某区域2014年土地利用现状数据为研究对象,实证分析结果表明,优化模型能够实现土地环境友好和总体资源节约下的优化配置,其算法效率较传统算法提高61.38%。
To provide a reference and decision-making for an optimal utilization of land space and urban land planning within a friendly environment and overall resource conservation, this paper proposed a new optimal allocation model of urban land use space based on the RLUAM model with a sine cosine optimization on the basis of the traditional one and selected some current data of land utilization in a region of Shanghai 2014 as the object to validate the algorithm's validity so as to indicate that the optimal model was able to realize the optimal allocation for land within a friendly environment and resource conservation and the efficiency of its algorithm improved 61.38% than a traditional algorithm.
