Research On Environmental Impact Database And Integrated Assessment Model Of Ecological Road

Ecological road is a new important trend in the world. Contrasting theories and project instances of road's environmental impact assessment at home and abroad,this paper put forward the definition of ecological road and lots of questions for discussion about ecological engineering and roading in the future.In order to construct ecological road and actualize durative development of road's construction,a definite evaluation of road's environmental impact is especially important. So establishing a rational assessment model and a system of evaluating indicators is the very sticking point. Based on interrelated researches on BaoTian-expressway,the criterion of road's environmental impact assessment,fuzzy mathematics,a software named Map3d,language of Visual Basic and language of C++, this paper established a consummate system of evaluating indicators of ecological road's environmental impact assessment and put forward a quantitative assessment model about ecological road. At the meantime,the author compiled a database of road's environmental information and some interrelated programmes to actualize data input,data storage,data inquiry and complex calculations of the model.Researched on environment noise,mass of atmosphere,water loss and soil erosion and some other evaluating indicators about ecological road,this paper put forward corresponding prediction models and quantitative calculation procedures. These quantitative prediction models make it more convenient for normalization of road's environmental impact assessment.Road's construction may influence environment of road's covered way. So we must analyse these impact and find a feasible program. Only in this way,can the relationship between economic development and ecological environment be compatible and development of road's construction be continuous. Research findings of this paper will advance technological level of road's construction in our country more or less.
