STUDY ON OUTDOOR THERMAL ENVIRONMENT OF CAMPUS BASED ON GIS

Abstract

In recent years, the campus population and the buildings of Jiangsu University have increased
and the pattern of the micro-city has preliminarily formed. The data of outdoor thermal environment of
campus based on Geographic Information System (GIS) has found that the average temperature difference of
outdoor temperature in space distribution in Jiangsu University is about 1℃. Five different underlying
surfaces have a great influence on the outdoor thermal environment of campus, and the daily variation of
temperature showed an inverted "V" single peak curve. The daily variation of temperature on the concrete
road (direct sunlight) is approximately 4℃ above that of the grassland at the time of 14:00. The temperature
of the concrete road (direct sunlight) is higher than that of the concrete road (shadows), and the temperature
difference between them is about 1℃. At the same time, five suggestions have been proposed for the
improvement of outdoor thermal environment in Jiangsu University according to the results.
