The Method Of Integrated Assessment Of Highway Environmental Impact Based On Fuzzy Mathematics

This paper bases itself upon environmental impact of the highway construction project, as well as upon the developing situation of road construction in China. Integrating the latest scientific results and experience in China and abroad, the paper investigates into the integrated assessments' methods and application of environmental impact of the highway construction project . Particularly, the paper studies the following elements of integrated assessment of highway construction project environmental impact, i.e. integrated assessment's index system, filtration of assessment factors, weighted assessment factors, integrated assessment and its intelligentization of the integrated assessment of highway environmental impact 1.Integrated assessment index system of environmental impact of highway construction projectAnalyzing the deficiency of index system of the integrated assessment of highway construction project environmental impact in China, studies the comprehensive and reasonable assessment index system, improves the design in assessment index system and the hiberarchy of the numerous factors in index system.2.Filtration of assessment factors Analyzing the filtration methods of assessment factors of highway construction project environmental impact, studying the basic principle in factor filtration, and putting forward an extensively applicable filtration method of factors of highway environmental impact integrated assessment based on Grey Theory.3.weighted assessment factorsAnalyzing how to decide each factor's weight in integrated assessment of environment impact. Using classfication theory and matrix theory, the article puts forward a new method on how to decide the factor's weight4.Integrated assessment of highway environmental impactAnalyzing the current main integrated assessment methods, and studing the fuzzy and changing features of highway environmental impact, Using the basic theory of Fuzzy mathematics. integrating the quantitative index and qualitative index, the article brings forward a mathematic model for the ingrated assessment of highway environmental impact, and also applies to practice5.The intelligentized system for ingrated assessment of highway environmental impactUsing computer language C++, we can develop a intelligentized system based on the above mentioned assessment technology with simply and friendly interface and easy to operate, which can make highway environment impact ingrate assessment intelligentized so as to adapt the development of environmental impact assessment.
