Highway Construction Project Areas Along The Ecological Environment Bearing Capacity Analysis And Research

With the quick development of highways in our country, the importance of environmental impact assessment (EIA) of highway construction becomes more and more obvious. This paper has put forward the viewpoint to analysis the Ecological Environment Carrying Capacity (EECC) of the reg ons along the highways, and this will speed up the development of EIA of highway and economy assessment of project feasibility research.The main environmental problems caused by land used by highway permanent were discussed at first, and the EECC of the regions along the highways was analysis and assessed from the view of resource carrying c ipacity and environment carrying capacity respectively. In the paper, the author h;is put forward the viewpoint to analysis the Ecological Environment Carrying Capacity (EECC) of the regions along the highways, established the index systems of EECC based on analysis of the relation between highway construction and EECC, and study some quantitative method of EECC especially for water resource carrying capacity, land carrying capacity and air pollution carrying capacity. Finally the basic consideration for the comprehensive assessment of EECC of regions along the highway v/as discussed.
