Optimization Method of Spatial Element Layout of Urban Landscape Architecture Based on Parthenogenetic Algorithm
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.
