摘要
为了提高城市风景园林空间元素布局优化的合理性,提出一种基于单亲遗传算法的城市风景园林空间元素布局优化方法.该方法首先对城市风景园林空间元素布局图像进行归一化处理,将图像分解成不同方向上的子带,得到城市风景园林空间元素布局的加权无向图;其次,构建空间元素布局图像边缘的纹理特征向量集合,提取城市风景园林空间元素布局特征,并基于此构建元素布局优化的因素体系,根据评价指标的信息量权重和价值量权重,构建空间元素布局优化模型;最后,利用单亲遗传算法求解布局优化模型,实现城市风景园林空间元素的布局优化.实验结果表明,经过该方法优化后,城市风景园林的环境质量显著提高,布局优化的合理性指数提升至 0.95以上.
Abstract
In order to improve the rationality of optimizing the layout of urban landscape architecture spatial elements,a Parthe-no-genetic algorithm method for optimizing the layout of urban landscape architecture spatial elements is proposed.By normali-zing the layout image of urban landscape garden spatial elements,the image was decomposed into sub bands in different direc-tions to obtain a weighted undirected graph of the layout.Constructed a set of texture feature vectors for image edges and ex-tract element layout features.Constructed a factor system for optimizing element layout,and construct a spatial element layout optimization model based on the information weight and value weight of evaluation indicators.Using Partheno-genetic algorithm to solve layout optimization model and achieve layout optimization of spatial elements in urban landscape architecture.The ex-perimental results show that the environmental quality of urban landscape architecture has significantly improved after optimi-zing the methods in the article,and the rationality index of layout optimization has been increased to above 0.95.
