摘要
为评估高速公路绿化所产生的生态效益,选取水土保持、固碳释氧、净化空气3个指标,通过文献调研和公式推导,提出生态效益评估方法,并应用该方法对贵州省思遵高速公路绿化的生态效益进行计算。结果表明:思遵高速公路绿化创造了较可观的生态价值;在绿化实施5.17年后,累计产生的生态效益能够与绿化工程建安费持平。
In order to evaluate ecological benefits produced by greening on expressways,this paper selects3 indices,i. e. conservation of water and land,carbon fixation and oxygen release and purification of air.The paper proposes an evaluation method for ecological benefits via literature research and formula derivation and calculates the ecological benefits of greening on Sinan- Zunyi Expressway in Guizhou Province by means of this method. The results show that greening on Sinan- Zunyi Expressway creates significant ecological values; and the accumulative ecological benefits produced after implementation of greening for 5. 17 years can approximate construction and installation costs of the greening project.
