The Role Of Parklands In Improving Urban Microclimates To Combat Pollution

摘要

The climate of a conurbation is of great importance, in particular for public health and to provide a good environment. Town planning should take into account how it can influence microclimate, especially in view of pollutant emissions by internal combustion engines. This article provides case studies of the effect of parklands on temperature, humidity and pollution, based on a series of formal measurements. Analysis of climatic data has found that gardens and parklands are responsible for significant precipitation. The present examples conform to this pattern. The author shows the influence of different types of garden on temperature, humidity, wind, precipitation and air pollution. The results clearly show the important role of parklands in urban areas. Such gardens are the least polluted places in a town. Breezes generated by the parklands repel and disperse pollutants, while gardens contribute considerably to the air quality in cities.
