摘要

为了提高绿地景观布局优化的效果，缩短景观布局优化的时间，本文提出了一种基于跨越式算法的城市道路绿地景观布局优化方法。首先，利用GIS采集道路景观布局数据。然后，采用层次分析法计算指标权重。采用蛙跳算法构造适应度目标函数，求解适应度值。最后对适应度值从好到坏进行排序，判断当前输出的最优值是否为全局最优值，得到最终的景观布局优化方案。实验结果表明，该方法的绿地景观布局优化时间仅为8.3 s，景观布局的合理性高达99.02%，表明该方法能够取得较好的道路绿地景观布局优化效果。

An optimisation method of urban road green space landscape layout based on leapfrog algorithm

To improve the effect of green space landscape layout optimisation and shorten the time-consuming of view layout optimisation, this paper proposes an urban road green space landscape layout optimisation method based on leapfrog algorithm. Firstly, GIS is used to collect road landscape layout data. Then, the index weight is calculated by analytic hierarchy process. The frog-leaping algorithm is used to construct the fitness objective function and solve the fitness value. Finally, the fitness values are sorted from good to bad to judge whether the current output optimal value is the global optimal value, and the final landscape layout optimisation scheme is obtained. The experimental results show that the green space landscape layout optimisation time of this method is only 8.3 s, and the rationality of landscape layout is as high as 99.02%, which shows that this method can have a good effect of road green space landscape layout optimisation.
