Wetland Ecosystem Service Evaluation of Fenhe River

To improve the invironment of Fenhe River basin, river wetland ecosystem restoration project was planned. Four methods were applied in this paper to evaluate the wetland ecosystem services according to the plan, which were market value method, shadow project method, results reference method and expense payment method.The results showed that the total value was 234 million rmb yuan, in which the value of water purification was the biggest, accounting for 46.1%. However, as not all the functions were taken into consideration during the study, smaller result was produced. Meanwhile, according to the main functions of the five parts in the plan, their basic values were calculated. It suggested that the basic value was determined by both area and value coefficient. The third part Yi Dam to Er Dam had the highest value because of the larger area and the biggest value coefficient.
