【摘要】：我国高速公路迅猛发展,在带动社会经济发展的同时环境问题也日益突显。高速公路施工期时间长对环境影响较大,尤其对生态环境造成的影响是长久的,不可逆的。目前对高速公路环境保护的研究大多是建设前期的环境影响评价和运营期的环境影响后评价。在此背景下,文章针对高速公路施工期环保效果评价进行了研究探索。文章首先介绍了高速公路施工期对环境的主要影响及相应的环保措施,综合评价理论,并对高速公路施工期环保效果进行界定。在此基础上,对高速公路施工期环保效果评价指标进行初选,然后通过专家打分法和数理统计法对评价指标进行筛选,确定高速公路施工期环保效果评价指标体系,明确指标评价标准。将层次分析法和聚类分析法结合确定权重,弱化了层次分析法主观性太强的缺点,使权重确定更合理。运用灰色系统综合评价建立高速公路施工期环保效果评价模型,对实例进行评价,并对评价结果进行分析,结合项目实际情况给予改进意见。实例证明了灰色系统评价模型的实用性和系统性,它可以实现对高速公路施工期环保效果评价指标体系的逐层分析,较深入的了解各指标层的优点与不足以及各指标的内在联系,更有利于施工企业针对性的进行改进。高速公路施工期环保效果评价不仅为政府、业主方提供环保效果评价准则,也可以指导施工企业环保措施的实施和改进,推进高速公路施工期环境保护。
[Abstract]:The rapid development of our country expressway, driven in the social and economic development and environmental issues are also increasingly prominent. A long period of time of highway construction on environmental impact, especially the impact on the ecological environment is long, irreversible. The current research on the highway environmental protection are environmental impact assessment prior to the construction and operation period the environmental impact assessment. Under this background, the research aiming at the highway construction period environmental effect evaluation. This paper firstly introduces the main influence of freeway construction on the environment and the corresponding environmental protection measures, comprehensive evaluation theory, and the effect of environmental protection of highway construction period are defined. On this basis, the primary evaluation index the highway construction period environmental protection effect, then the evaluation indexes were selected by Delphi method and mathematical statistics method, to determine the highway The evaluation index system of environmental protection effect during the construction period, clear indicators of evaluation criteria. Combining the weights of AHP and cluster analysis method, analytic hierarchy process weakens the disadvantage, which makes the weight more reasonable. The establishment of highway construction period environmental effect evaluation model using grey system comprehensive evaluation, evaluation of examples, and the evaluation results of the analysis, combined with the actual situation of the project to give suggestions for improvement. Examples to prove the practicality and system evaluation model of grey system, it can realize the layer analysis of highway construction period environmental effect evaluation index system, internal relations more in-depth understanding the advantages of each index layer and the insufficiency as well as the index, more conducive to the construction of enterprises targeted for improvement. Evaluation of highway construction period environmental protection effect not only for the government, the owners to provide environmental protection effect evaluation criterion, also It can guide the implementation and improvement of environmental protection measures for construction enterprises and promote the environmental protection during the construction period of the expressway.
