随着经济的发展,基础设施建设的大量展开,公路建设活动对生态环境的压力日渐突出,已经成为生态环境破坏的主要原因之一。本文以环境经济学与生态系统服务价值为依据,从公路建设所带来的环境污染和生态破坏两个方面分析公路建设对路域生态环境的负面效应,并考虑环境保护工程带来的正面效应,兼顾环保工程建设费用,探索建立公路建设生态环境效益评价的指标体系,并分析了其计算方法和适用条件。
With the development of economy and the massive expansion of infrastructure construction, the pressure of highway construction activities on the ecological environment has become increasingly prominent, which has become one of the major causes of ecological environment destruction. Based on the value of environmental economics and ecosystem services, this paper analyzes the negative effects of highway construction on road ecological environment from two aspects of environmental pollution and ecological damage caused by highway construction, and considers the positive effects brought by environmental protection projects , Taking into account the cost of construction of environmental protection projects and exploring the establishment of an index system for evaluating the ecological benefits of highway construction. The calculation methods and applicable conditions are also analyzed.
