Research On The Optimization Strategy Of Urban Coastal Space Under The Influence Of Air Anion’s Temporal And Spatial Distribution

Looking back on the mutual development of urban planning and public health,health has always been a topic that people cannot avoid.Nowadays,people pay more attention to health,and their demands for high-quality air in cities are becoming stronger.Air quality is an important factor affecting human health.Therefore,it is proposed to meet public health demands through planning interventions from the perspective of negative air ions.Air negative ions are a part of the air component and have functions such as medical care and air purification.As an important indicator to evaluate whether the urban air is good,it has a positive effect on public health.For the coastal space,it has abundant health resources and contains a relatively high concentration of negative air ions,which is an important space carrier to promote public health.First of all,the article reviews the relevant research on air anions,exploring the relationship between air anions in coastal space and public health.Based on the characteristics of air anions in coastal space and planning factors that affect the spatial and temporal distribution of air anions,it is carried out under the condition of air anion concentration distribution.The research on the layout of the coastal space provides a theoretical basis.Then,based on the theoretical basis and considering the actual situation,the coastal area of Dalian Heishijiao-Xinghai Square is selected as the empirical research object.Based on the division of land functional units,combined with spatial layout elements such as building layout forms,green plants,and road traffic,Determine the measured sample points of each unit,conduct on-site monitoring of air ion concentration,analyze the temporal and spatial distribution characteristics of air anion concentration,use ARCGIS interpolation to analyze its distribution pattern,and obtain the air quality level in the area according to relevant evaluation standards.Secondly,the correlation analysis between air anions and microclimate factors such as temperature,humidity,wind speed,etc.,based on the correlation significance,determines that the wind speed has a practical effect on air anions,uses phonics software to simulate the wind environment,and simulates The results are compared with the spatial distribution of negative air ions,regional spatial layout,and public crowded areas,and the factors affecting the distribution of negative air ions are obtained,which provides targeted guidance for optimizing the spatial layout and promoting public health.Finally,in combination with public health needs,it is concluded that blue and green are used as the core organization function to build a high-anion living unit,combined with the prevailing wind direction,to open the "wind-negative" channel,optimize the architectural space layout,and create diverse anion breathing areas and other coastal areas Space optimization strategy to achieve the optimization of the coastal space with negative air ions as the medium,and then achieve the effect of health promotion.
