Shaping Air Negative Ion Life Circles in the Coastal Space for Healthy Cities

Abstract

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. The coastal space has abundant health resources and contains a high concentration of negative air ions, which is an important space carrier to promote public health. Combining with the health effects of negative air ions, taking the influence of urban space layout on the concentration of negative air ions as the starting point, analyze the relationship between coastal space reserves and negative ion generation, urban spatial spread, and changes in negative ion concentration, spatial configuration and the acquisition of negative oxygen ions. On this basis, combined with public health needs, it is concluded that blue and green are used as the core organization function to build a high-negative ion living unit, and combined with the prevailing wind direction, the "wind-negative ion" channel is opened, the architectural space layout is optimized, and a variety of negative ion breathing areas are created. And other coastal area space optimization strategies, to achieve the optimization of the coastal space with negative air ions as the medium, and then achieve the effect of health promotion.
