摘　　要：城市热岛区已成为一大环境公害.文章利用AUSSSM TOOL软件,对几个典型的小区热环境进行了数值模拟.结果表明,通过增加绿地面积,减少人为热排放以及增大各表面太阳辐射反射率,能够明显缓解小区的热岛效应,可使小区日平均气温降低1.5-2.9℃,亦使最高气温下降4.6℃.With the AUSSSM TOOL software employed, the thermal environments of several typical residence communities are numerically simulated. The results show that increasing green land area, reducing anthropogenic heat and increasing the solar radiation reflectivity of each surface can distinctly alleviate the urban heat island effect, resulting in a decrease in daily average temperature of l. 5- 2.9 ℃ and the fall of the highest temperature of 4.6℃.
