- Abstract:

With the rapid development of the construction of expressway and the increasing sense of environment protection of mankind in our country,people pay more attention to the negative ecological and scenic effects by the traditional slope engineering protection methods.As an environmentally compatible and cost-efficient alternative for roadside management,soil bioengineering has become increasingly important and attractive.However,the advantages of soil bioengineering are so difficult to quantify that superiorities of soil bioengineering cannot be embodied when compared with other protection methods,and the popularization of the method is highly influenced.The benefits and costs of highway slope protections were analyzed from different aspects,for example the value of vegetation sequestrating carbon dioxide and releasing oxygen,the value of conserving the source of water,the value of restraining dusts,the value of sequestrating sulfur dioxide,the value of landscape improving,the costs of construction and maintenance etc.The methods how to estimate the benefits quantitatively were put forward.The case analytical results demonstrate that soil bioengineering method,if technically feasible,could be adopted to produce equal or better economic and environmental results.The approach could be used as a tool for comparing the slope protection methods.
