Environmental Effects Analysis Of Urban Green Garden

Urban green garden,which have self-purification capacity and the ability of self-adjust ,is an important part of the city ecosystem,and the urban green garden can take a important role in improving the Eco-environmental quality and beautification of the urban landscape.Some samples from different types of garden green have been analysed in the research,and the results showed that plants would absorb solar radiation (51%～93%), brought down temperature(0.7～1.3℃), increased humidity(0.3～1.6hPa), and resort dust (4.68～11.27 mg/m3). In addition, the plant also have effectiveness of keep the balance of carbon and oxygen, purified air,sterilization, reduced noise and so on. Park's ambient air quality significantly higher than that in residential areas or roads ; parks have the lowest level of bacteria, while the bacterial content of bare land is much higher than green.;more bigger green area and more dense canopy, more significant noise reduction capability.So that the urban green space can not replaced by other urban infrastructure in maintaining the ecological balance and improving the urban ecological environment. This dissertation has took aim on the qualitative & quantitative analysis to the environmental effects of urban green garden ,and some rationalization proposals to the planning and building of the urban green garden have make in the dissertation.which have some guide significance to improve the environmental effect of the urban green garden.
