The Discussion Of The Atmospheric Environment Capacity In Plan Impact Environment Assessment

Nowadays China is building the "harmonious society" where the elements of society, economy, environment and resource are at the state of sustainable development. The harmonious development of the economy and environment is significant. In China, the Plan Environment Impact Assessment(PEIA)are very important, and wherein the Environment Capacity of the air pollutants is deserving.Taking the elements of strategy orientation, environmental harmony and case practicability into account, the papers choose the "the Quanhui Petrochemical Industrial Park Plan of Meizhouwan Bay Petrochemical Industrial Base in Fujian Province"(Q-Plan) as the case for the research in the papers. The Quanhui Petrochemical Industrial Park Plan is one of three parts of the Meizhouwan Bay Petrochemical Industrial Base. It plays an important role in "the Economic Zone on the Western Coast of the Taiwan Straits" and "the Outline of the Eleventh Five-Year Plan in Fujian Province". The petrochemical industry is a good booster for the economy and otherwise it is a big peacebreaker for the environment. Therefore, the petrochemical industry is a perfect choice for the case.Firstly, the papers summarize the researches on the Atmospheric Environment Capacity(AEC), especially the dominating atmosphere diffusion models and the familiar calculation ways for AECs. In the basis, the goals, the content and the approach are fixed. The calculation ways are the A-P Value, the Simulation and the Linearity Plan.Secondly, The papers finish the brief introduction of the natural and social environments, the content of Q-Plan, the weather condition analysis, the atmosphere environment quality variation trend analysis, the pollution sources analysis and so on. Furthermore, the scenarios are integrated with the way of Linearity Plan into the case. The values for the AECs are calculated in different scenarios.Finally, the relations between the AECs and the parameters are evaluated for the advice of the AECs. All the analyses help the total quantity control of pollutants discharge and the environment management.
