摘要:
随着我国高速公路建设快速发展以及人类环境保护意识的不断增强,公路边坡传统的工程防护对生态环境和景观所产生的负面效应越来越受到人们的关注.作为一种环保和经济的方法,生态防护变得越来越重要和有吸引力.但由于生态防护的优点难以量化.使得在护坡方案比选时生态防护的优势体现不出来,影响了生态防护的推广.从多个方面对边坡防护的效益和费用进行分析,如植被吸收CO2和释放O2价值、涵养水源价值、滞尘价值、吸收SO2价值、景观提升价值及边坡防护的建设及维护费用,并提出具体的定量估算方法.实例分析显示,当适用条件合适时.生态防护可以达到更好的经济和环境效益.所提方法可以用于边坡防护方案比选.
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.
