The Influence of Electric Power Structure Adjustment Projects on SO_2 Total Emission Amount in Xinjiang

Energy is the material foundation of economic and social development.As an important energy resource,the exploitation and the utilization of electric power also generate environmental problems.With the rapid development of the electric industrial of Xinjiang,the emission amount of sulphur dioxide pollutant produced by fossil power plants have increased year by year,but the serious environmental pollutions have become a key confined effect to sustainable development of Xinjiang.Total emission control of pollutants is a very effective method to control the pollutant emission amount and to improve regional environmental qualities.In the 2010a,the SO_2 total emission amount in Xinjiang must be less than 51.9×104t,and the SO_2 total emission amount of fossil power plants must be less than 16.6×104t.Combine with the quantitative mathematics model and scenarios analysis methods,the paper puts forward three projects of electric power structure adjustment and three projects of pollution control levels of fossil power plants.By calculates the SO_2 total emission amount of these projects in 2010a in Xinjiang,the paper reach the conclusion that the adjustment strategy of Xinjiang electric power structure is very beneficial and very essential and the middle or high projects should be the first choice for electric power structure adjustment in 2010a.That is the proportion of fossil power in electric power structure should be declined to 70%～65%,while the proportion of hydro and wind power in electric power structure should be increased to 70%～65%.At the same time,it needs to improve the pollution control level to make the pollutant emission coefficient reduced the 55%～50% as the end of "tenth five".
