英文摘要	Conference Name:2nd International Conference on Energy, Environment and Sustainable Development, EESD 2012. Conference Address: Jilin, China. Time:October 12, 2012 - October 14, 2012.; Several dispersing and small-scale measures such as permeable pavements, green streets,and ecological roofs for sustainable development to mitigate the heat island effect were proposed, and there the following environmental benefits and economic benefits were analyzed. Permeable pavements effectively relieve the negative influence on urban ecology caused by urban harden ground. As well, permeable pavements link up soil and air, making the ground warm in winter and cool in summer, which increase the sense of living comfort in the city. The research shows that when area of the urban roads increase to 25% of the whole city, completely applying the asphalt pavement roads can make the temperature 1 ~ 1. 5 °C lower on the whole in downtown district. Green streets are beautiful street landscapes which planting green plants such as shade trees on both sides of the streets. On one hand it can keep cool, and mitigate urban heat island effect. On the other hand it can absorb the greenhouse gases such as carbon dioxide, and maintain carbon-oxygen balance. Shade trees effectively prevent sunlight from hitting to the ground, and make the sun radiation intensity significantly lower than the harden ground and the lawn. The sun radiation intensity can be reduced by 80% or more on occasion that there have trees. Ecological roofs can adjust the temperature, and form natural air conditioning which is beneficial to improve the air quality. Research data show that in summer, on average, temperature of the ecological roofs are 2.6°C lower than the bare cement roofs and in winter which are 0.84°C higher than the cement ones. Then the implementation of the feasibility through the above mentioned sustainable development measures to achieve the minimum impact on the environment, which play an important role in reducing urban surface temperature was discussed. The prospect of implementing the technology in China that usually appeared in high densely-populated urban areas was given at the end of this paper. ? (2013) Trans Tech Publications, Switzerland.
