Paper Abstract
Each city has its unique urban form. The importance of urban form on sustainable development has been recognized in
recent years. Traditionally, air quality modelling in a city is in a mesoscale with grid resolution of kilometers, regardless
of its urban form. This paper introduces a GIS-based air quality and noise model system developed to study the built
environment of highly compact urban forms. Compared with traditional mesoscale air quality model system, the present
model system has a higher spatial resolution down to individual buildings along both sides of the street. Applying the
developed model system in the Macao Peninsula with highly compact urban forms, the average spatial resolution of
input and output data is as high as 174 receptor points per km2. Based on this input/output dataset with a high spatial
resolution, this study shows that even the highly compact urban forms can be fragmented into a very small geographic
scale of less than 3 km2. This is due to the significant temporal variation of urban development. The variation of urban
form in each fragment in turn affects air dispersion, traffic condition, and thus air quality and noise in a measurable
scale.
