Abstract: Taking highway engineering as example，environmental space is divided into six aspects，including the water envi- ronment，soil environment，atmospheric environment，sound environment，biological environment and landscape environ- ment．Monetary efficiency value calculation model of ecological restoration is established，through various evaluation meth- ods，including the shadow engineering method，protective cost method，recovery ／reset cost method．Then the engineering data of case study are involved in the model，so the feasibility of the model is verified and evaluation results are obtained． The proposed model proves that environmental space will produce a great benefit value after the implementation of ecological restoration．

Key words: ecological restoration, highway, benefit value, monetization

摘要： 以公路工程为样例，将环境空间分为水环境、土壤环境、大气环境、声环境、生物环境、景观环境等6个层面，通 过影子工程法、防护费用法、恢复／重置费用法等评估方法建立生态恢复效益货币价值计算模型，并代入实例工程数 据，验证模型的可行性，从而获得评价结果，证明生态恢复工程实施后将产生巨大的效益价值。
