Numerical Study on the Influence of Rivers on the Urban Microclimate: A Case Study in Chengdu, China

The urban heat island phenomenon in large cities is becoming increasingly serious as urbanization continues to develop, seriously affecting the lives of residents. Rivers can effectively alleviate islands and improve thermal comfort riverfront space summer. Thus, effect rivers on microclimate environment studied this work. A section Fu River inland city Chengdu was selected research object, a combination experimental numerical simulation methods employed. ENVI-met software used study river’s influence air temperature, relative humidity, space. measured parameters are first verify accuracy results, which then employed carry out research. results suggest that different types underlying surfaces have varying impacts temperature humidity. significant cooling regional environment, roads warming temperature. order follows: > trees. an obvious humidifying air, little humidity trees roads. outdoor predicted mean vote (PMV) reveal rivers, trees, green plants individuals downwind.
