【摘要】：我国高速公路修建里程逐年增加,项目建设及高速公路投入营运都将产生不可忽略的环境问题,虽然建设期产生的环境影响是短时的,在施工期结束后可以消失,但是高速公路营运产生的长期影响是不可忽略的。本文提出在初步设计阶段结束后,对高速公路使用年限内将产生的环境影响进行逐年预测,以提出预防和改进的措施。高速公路环境影响评价指标选择的合理与否是评价的关键之一,本文从建设项目对环境产生的影响进行分析,结合相关的规范及已有研究成果,整理出分层评价指标体系。同时,考虑到高速公路建设产生的环境成本不可忽视性,提出了将环境成本作为评价指标的一大方面,并从交通产生的影响角度给出了环境成本主要两个方面(环境保护恢复成本和环境污染治理成本)的计算公式。为了方便用户选择的灵活性,提出将高速公路环境影响评价指标分为必须指标和可选指标。高速公路环境影响是一个复杂多变的系统,合理选择评价综合量化模型是进行科学的环境影响评价的又一个关键。本文在初步设计阶段后对道路使用年限内的环境影响进行逐年评价,评价单元具有相同的属性,而本文建立的环境影响评价指标又是分层结构体系,首次提出将双层DEA模型应用到高速公路环境影响评价中。对评价指标进行初步筛选以及深度处理,选择对双层DEA评价模型影响程度高的指标进行评价。考虑到指标之间的灰色关联性,本文采用GRA与SE-DEA相结合的方法进行指标深度选择,并与传统的GRA筛选模型方法进行了对比,得出GRA与SE-DEA相结合的方法更有效。最后,以广东省潮州至惠州路段的潮惠高速公路为实例进行评价研究,结果表明其在25年的使用年限内有超过75%的年限相对效率等于1,说明该条高速公路未来年内的环境影响程度是可以接受的。
[Abstract]:The mileage of expressway construction in our country increases year by year, the project construction and the expressway put into operation will produce the environment problem which can not be ignored, although the environmental impact produced during the construction period is short term. After the end of the construction period can disappear, but the long-term impact of highway operation can not be ignored. The environmental impact will be predicted year by year in order to put forward the measures of prevention and improvement. It is one of the keys to evaluate whether the selection of expressway environmental impact assessment index is reasonable or not. This paper analyzes the impact of construction projects on the environment, combines the relevant norms and existing research results, collates the hierarchical evaluation index system. At the same time. Considering that the environmental cost of expressway construction can not be ignored, the paper puts forward that the environmental cost should be regarded as an important aspect of the evaluation index. And from the point of view of the impact of traffic, the paper gives the calculation formulas of two main aspects of environmental cost (environmental protection recovery cost and environmental pollution control cost), in order to facilitate the flexibility of users' choice. The environmental impact assessment index of expressway is divided into necessary index and optional index. Expressway environmental impact is a complex and changeable system. Reasonable selection of comprehensive quantitative evaluation model is another key to scientific environmental impact assessment. This paper evaluates the environmental impact of road service life year by year after the preliminary design stage. The evaluation unit has the same attribute, and the environmental impact assessment index established in this paper is a hierarchical structure system. It is the first time to apply double-layer DEA model to highway environmental impact assessment. The indexes with high influence degree are selected to evaluate the double-layer DEA evaluation model. Considering the grey correlation between the indicators, this paper adopts the method of combining GRA and SE-DEA to select the index depth. And compared with the traditional GRA screening model, it is concluded that the combination of GRA and SE-DEA is more effective. Finally. Taking Chaohui Expressway from Chaozhou to Huizhou in Guangdong Province as an example, the results show that the relative efficiency of Chaohui Expressway has more than 75% years of service life in 25 years. This shows that the environmental impact of the highway in the coming year is acceptable.
