Positively Using Heat Island to modify City Environment
Heat Island effect was caused by the difference in the effects of the sun heating the urban and suburban region where there are abundant of constructions and plants respectively, and it brought some problems about the living environment for the people. The urban region where there is almost only concrete and iron made constructions became too hot and sometimes unacceptable for people to stay, and the haze is also hard to eliminate by afforestation, haze is significant a risk to people’s health. However, this effect could also be positively used. As the heat island causes temperature gradient between the city center and the suburban area where the afforestation is more abundant, the city could be redesigned as a structure of center-industry and surrounding-living; thereby, not only the region where people live would be cooler and healthier, but also the heat island would be utilized as a huge chimney to extract the industrial pollution including haze out of the city, making the suburban regions safer and afforestation is effective again to eliminating haze from where people live. A full understanding about entropy in a view of thermodynamics as well as its application to the photosynthesis are given, the photosynthesis in plants absorbed the heat from the sunlight and stored it in forms of chemical energy inside the carbohydrates produced throughout the synthesis generates minus entropy compared to the sunlight directly dissipated into heat in urban region, the energy from the sunlight as well as the minus entropy thereof, which is a potential for heat to dissipate, was stored in the products of photosynthesis, i.e., the carbohydrates etc. which provide food for the whole biosphere on the earth; therefore, the temperature would be significantly lowered by plants in afforested regions.
