公路路域生态环境影响评价指标体系的建立

Establishment of Highway Area Ecological Environmental Impact Assessment Index System

公路大规模建设导致生态负效应,对生态环境产生了巨大的破坏作用。通过对公路路域的自然生态环境、环境污染防治、景观与绿化等方面进行综合分析,确定了公路路域生态环境影响评价指标,建立了生态环境影响评价指标体系。公路路域生态环境状况分为三大类:生态资源状况、环境质量状况与绿化景观状况,其中生态资源状况包括土地资源、水资源、生物资源;环境质量状况包括污水处理状况、大气污染状况、噪声状况和固体废弃物处理状况;绿化景观状况包括绿化状况和景观状况。

The large scale construction of highway results in ecological negative effect, and causes the huge damage on ecological environment. According to the comprehensive analysis on the natural ecological environment, environmental pollution prevention and landscape greening, the ecological environmental impact assessment index of highway area is determined and the ecological environmental impact assessment index system is established. The ecological environmental aspects of highway area are divided into three parts of ecological resource, environmental quality and greening landscape, in which the part of ecological resource includes the land, water and biology, the part of environmental quality includes the sewage treatment,atmospheric pollution, noise and solid waste disposal, and the part of greening landscape includes the greening and landscape.
