Study On Regional Rural Highway Environmental Impact Performance Evaluation

In recent years the Central Committee of CPC and the State Department attached great importance to"peasantry, country and agriculture". And a series of policy to develop rural economy has been formulated, in which the countryside highway construction hold important status. During"the eleventh five years planning"period, the government put out 100,000,000,000 Yuan to construct the countryside road. At present, the countryside roads already had the suitable scale and basically formed its own network that can connect most of the farmers, so that it facilitated the residents'journey, promoted the rural economic development. Simultaneously the large-scale countryside highway construction has also had many influences on the periphery environment, which needs to be weighted and estimated in good season, in order to guarantee the sustainable development of environment and society.The single countryside road project has small construction scale, widespread distribution, low technical class and small volume of traffic, so the single project's environmental effect is limited, but the numerous projects cumulated and produced synthesis influence on environment that cannot be ignored. Therefore this research took numerous countryside road projects in some area coverage as the object of study, analyzed the countryside roads characteristic, the countryside roads environment characteristic and the characteristic of countryside road effects on the environmental. By using the Value- -Goals- - Objectives- -Criteria logical system and the evaluating indicator selection principle, this research deduced and constructed the region countryside road environmental effect achievements appraisal indicator system. It also analyzed each evaluating indicator attribute value computational method and the zero dimension, and discussed how to determine the evaluating indicator weight and which the assessment method is more suitable; Appling the fuzzy recognition principle and unifying the AHP weight determination method, the research established the multi-level fuzzy recognition quality synthetic evaluation model of regional countryside highway construction environmental effect quality synthetic evaluation, according to the region countryside highway construction to the environment influence.Using the quality synthetic evaluation method proposed in this research to evaluate the environmental effect of countryside road in Zhe Jiang Province, which confirmed the feasibility and the accuracy of this method. Following that, the research carried on the analysis to the measure results, and proposed the measure that reduces the environmental effect.
