Preliminary Studies On Highway Greening--Studies On Highway Greening Between Dali And Baoshan

Along with the quick development of highway, our country has more demand on highway greening. Highway greening on different areas on the spot and drivers' opinions by questionnaires were investigated. The temperature and humidity ecological benefits of different vegetations were determined. On the basis of scientific analysis, this paper summarized the theory of ecological environment renewal and landscape reconstruction.On the basis of highway greening project between Dali and Baoshan, based on the actual situation of Dabao highway, thinking from ecology, safety and landscape, the greening methods on Yunnan low mountain distract highway side slopes, interchange, and central reserve are summarized.1. The investigation on the spot of highway greening of Yunnan, Shanghai, Shandong, Beijing, etc. was made. The results show that there are many greening patterns, they have different effects on ecology, safety and landscape. The drivers' opinions on highway greening by questionnaires were investigated. The results show that the whole function varies from different greening patterns. And different district has particular stress.2. The determination of temperature and humidity on Beijing highway greenbelt was made. The results along with other ecological benefits show the gradation of greening patterns which can exert best ecological benefits: arbor with shrub and herbage> shrub with herbage>vine> herbage.3. On the basis of investigation along Dabao highway and preliminary greening research, practical measures on ecological environment protection and renewal, landscape protection and reconstruction are summarized. On the basis of the practice of Dabao highway greening, practical greening theories and technics of side slopes, interchange and central reserve are summarized.
