Study On Ecological Benefits Of The Green Foofs

At present, the city is developing rapidly, and the population is increasing. Emissions of waste gases and pollutants from human life and industrial production directly into the air or water without any treatment. It makes the urban air pollution and water pollution more and more serious. At the same time, the heat island and dry island effect become remarkable. The noise pollution, coming as a result, is also a threaten to health. In the development of modernization, the construction of land has greatly changed the nature of the area under the pad surface, in order to increase the waterproof area, resulting in rain flood frequency. And in the case that city land being tense at present, green roof appears to give people a new ecological means to solve the above problems, the ecological benefits of green roofs should not be underestimated. Firstly, green roof has the same efficacy with general green land inculding improve air quality, reducing acoustic noise reduction, improve the rainwater, relieve the heat island effect, reduce the temperature of the region and prevent the secondary pollution of the water quality, increase air humidity, regulating climate. And because of its special geographical location, green roof can also play a special role of general green to, such as multi-level purification, protect roof, reduce the indoor temperature, the efficacy of roof rainwater storage. This paper will do some research and summary on the concept, type and development of the green roof first, and make in-depth analysis on the most important six ecological benefits of the green roof. Comprehensive exposition on production and influence of pollution, related research on the mitigation of pollution by green roof, specific ecological efficiency technique and how to realize the ecological benefits of green roof. Put forward Some suggestions on the development of green roof, combining with the specific natural conditions, pollution, green land and economic construction in Beijing. Hope to provide reference for the future development of green roof.
