Study on Micro-climate of South Square in Nanjing Agricultural University Based on ENVI-met
Abstract： With the development of ecology and landscape science, with the deterioration of the urban environment, environmental adjustment and repair is becoming increasingly important. Existing research results show that the green garden that be designed scientific and reasonable can play a certain role on the cooling and humidification. To this end, in order to achieve the purpose of scientific design, the corresponding theoretical and technical support is essential. ENVI-met is a small site micro-climate simulation of excellent software, to a certain extent applied to the garden area. In this paper, ENVI-met is used to simulate the South Plaza of Nanjing Agricultural University. The factors influencing the microclimate in the field were analyzed from the aspects of temperature, humidity and wind speed, and the calculation of the human body comfort index was carried out according to the above data. Through the analysis of the results concluded: ①Plants have a certain cooling effect. ②Plants have moisturizing effects, which trees> shrubs> herbs. ③Buildings have a certain impact on microclimate.
