Energy Analysis And Environmental Impact Assessment Of The Power Plant And Its Surrounding Ecosystems

From an ecosystem perspective of sustainable development,study on the concept of ecological -exergy,the calculation method and its easy application in society and the ecosystem.Eco-exergy is divided into inorganic and organic exergy,accoding to this idea,the power plant and its surroundings can be seen as one part of the ecosystem,the energy flow and material flow in the plant can be calculated by the way of inorganic exergy.Through eco-environmental impact assessment,it can be concluded that the small changes of inorganic exergy in power plant will make kinds of possibilities in ecosystem.Besides,the cost of exergy is studied and and calculatied in examples,and then the exergy is expressed in the form of currency,which is helpful for people to do environmental impact assessment in scientific,improve the awareness of saving energy and reducing consumption and study the principle of ecosystem well.
