Abstract: Classification of ecosystem service including direct and indirect economic benefit, as well as evaluation of it including Substitute market techniques and simulation market techniques have been introduced in this paper, based on ecosystem service’s conception. The application of it in different ecosystem has been emphasized. A lot of studies show that environment pollution such as acid rain, heavy mental and abnormal climate have obviously made serious side effects on urban ecosystem functions, and caused great decrease in ecosystem service value. E.g. acid rain makes serious reduction of crops’ production, degradation of vegetation and acidification of soil and water; heavy metal accumulates and enriches in organism, which causes organism into chronic poisoning. In the end of the paper, it gives some suggestion on the evaluation of ecosystem services and the layout of the town, which emphasizes the consideration on economy consumption of the ecosystem recovery and cooperative effect the ecosystem service owns itself.
