摘要
为了优化城市生态环境、美化场地环境,提出了Delft3D污染物扩散模拟下生态园林景观环境中植物布局优化配置。选取某生态园林作为研究区,分析景观环境现状,得知植物布局配置出现的问题。采用Delft3D技术模拟景观地形,计算连续性、横向动量、对流扩散数值,获得污染物扩散模拟效果。根据当前水体环境中总氮、总磷、化学需氧量污染物扩散结果,结合植物的生长特点和当地的自然条件,完成生态园林景观环境中植物布局优化配置。通过实验,证明植物布局优化配置,可以提升绿化区域的生态效应和景观效果,增加植物的成活率,为创造生活与观赏景观环境。
In order to optimize the urban ecological environment and beautify the site environment,this paper puts forward the optimal allocation of plant layout in the ecological garden landscape environment under Delft3D pollutant diffusion simulation.Selecting an ecological garden as the research area,this paper analyzed the present situation of landscape environment and studied the problems in plant layout.Delft3D technology is used to simulate landscape topography,and the numerical values of continuity,lateral momentum and convection diffusion are calculated to obtain the simulation effect of pollutant diffusion.According to the diffusion results of total nitrogen,total phosphorus and chemical oxygen demand pollutants in the current water environment,combined with the growth characteristics of plants and local natural conditions,the optimal allocation of plant layout in the ecological garden landscape environment is completed.Through experiments,it is proved that the optimal allocation of plant layout can improve the ecological effect and landscape effect of greening areas,increase the survival rate of plants,and create a living and ornamental landscape environment.
