(2008), the predominance of impervious areas over green spaces would introduce the urban heat island (UHI) effect, in this case, in Melbourne, London and Shenyang. McPherson et al. (1994) indicated that UHI had negative impacts on the hydrological system, air quality, human well-being, and general ecosystem health. Oké et al. (1997) suggested that UHI is attenuated by expanding canopy cover and albedo, but Grimm et al. (2008) added that this solution has a high water demand, especially in a dry climate. It should be noted that the methodology of using randomly generated points to measure land use had certain advantages and disadvantages. Surveyors could quickly gain insight into land use in a particular area. However, the areas surveyed in this study were relatively small (4 km2) due to time and resource constraints, compared to the area of entire cities. Therefore, the results may not be generalized to all cities..
