Abstract/Contents: | Discusses the role of plants in the urban landscape. Explains that "climatically, urbanized centers with tall buildings, streets and other man-made structures are more temperate than open rural areas; they receive less solar radiation and have lower relative humidities and wind speeds; they experience a greater frequency of cloudiness and fog conditions and consistently higher levels of both gaseous and particulate pollutants." Suggests that "plants can be used to modify environmental conditions within the urban setting and serve to enhance esthetic [aesthetic] values. Discusses the man-made factors that influence the climate of the city. Explains that plants can provide useful services in pollution reduction (by absorbing carbon dioxide and releasing oxygen) and in sound abatement. Explains that "plants reduce noise levels by scattering sound waves. Leaves and stems provide a large amount of surface area, randomly arranged in space, to interfere with the transmission of acoustical energy." Concludes that "plants can exert a significant effect on the hostile urban environment. Though not a question of human survival, trees and shrubs contribute to the alleviation of noise, atmospheric dust and gas, as well as modifying climatic extremes of temperatures and wind. The concept of greenbelts around urban centers and along expressways, as well as green open space, needs further consideration in urban planning." |
