Method Studies And Their Applications On The Economic Evaluation Of Project

Environmental impact evaluation as part of project feasibility research; its conclusion plays an important role in determining the choice of the project. At present ,most people have already realized the importance and necessity of environmental impact appraisal. So, start environmental impact appraisal promptly in the feasible demonstration of the construction project, and there are some ripe methods, But the general question existing is only to making standard the influence appraising or proposing to the environmental issues of the building and production process of project construction in limited range, do not do intact appraisal on the extension or expansion environmental questions and negative effects of the project construction in the course. Only does the nature appraisal in limited environmental impact appraisal, negative effects in environmental impact do not go on economy quantize. So, it is unable to bring the economic losses that environmental impact cause into economic evaluation of the project, gives a great discount too, if bring environmental losses into project feasibility research in authenticity of commenting the project of ring, perhaps a lot of projects are not feasible; Therefore, it is very necessary to carry on economic evaluation for environmental impact of the construction project In order to fully realize the necessity and appraisal theoretical foundation which is built environmental impact economic evaluation of the project, this text, proceed from idea of sustainable development, use the benefit cost theory and environmental outside theory, structure the theoretical system of economic evaluation, in order to realize appraising on this basis , have chosen the economic indexes of environmental influence factors and economic appraisal index of environmental quality , have established the system of index , under the present social economic condition, economic appraisal index of environmental quality have paid close attention; Used the benefit cost analytical method, has made the appraised the result combined. Study through the theory and method of the above, structure the theoretical foundation of the proposition. Practice the respect, regard central heating project of the economic development zone of Urumqi as the case, through the understand of technological process ,analyzed the characteristic of environmental impact, Use the value the principle of environmental economics, According to discharging things mainly---SO2,TSP, estimate the cost of environment, and bring the environment damage cost into economic analysis of project, the results indicate economic benefits obviously reduced when compared with the economic benefits without environment damage. Adopting the theoretical research and preliminary practice, the economic evaluation of the environmental impact of the construction project is not merely essential, and feasible, the environmental administrative department should pursue progressively, catch the key index on the key influence of all kinds of projects first, implement the effective norm, make the environmental impact of the construction project appraise has a quality the promotion from the theory and practice, so as to meet modern socio-economic development's needs.
