摘要
为提升大气环境质量,以大气污染时空特征作为参考基准,设计景观园林绿化布局优化模型。利用综合污染指数评估与空间插值方法,分析当地大气污染时空特征;采用灰色系统理论处理布局初始序列计算演化参量求解离散序列微分方程,获取布局分析结果并构建布局转换函数,完成模型设计实现景观园林绿化布局优化。对比分析表明,所建模型提升了布局合理性与连通性,降低了大气污染物浓度与污染等级,对改善大气污染状况具有一定的有效性。
In order to improve the quality of atmospheric environment,the optimization model of landscape layout was designed based on the spatial and temporal characteristics of air pollution.The spatial-temporal characteristics of local air pollution were analyzed by comprehensive pollution index evaluation and spatial interpolation method.The initial sequence of layout was treated by grey system theory.The evolution parameters were calculated,the discrete sequence differential equations were solved and the layout analysis results were obtained.The layout conversion function was constructed to complete the model design and realize the optimization of landscape layout.The comparative analysis shows that the model improves the rationality and connectivity of the layout,reduces the concentration and pollution level of air pollutants,and has certain effectiveness in improving the air pollution situation.
