Abstract:: Based on understanding the structure function of the East Juyan Lake wetland, service function of the Wetland Ecosystem was divided into three aspects: society, economy and ecology according to the ecology theory. The evaluation index system of the wetland function value was set up by combining the wetland function performance, and the value of each function was quantified by energy analysis. The results showed that the total value of the East Juyan Lake wetland was 1.56×10²⁰sej, and the social value was 2.41×10¹⁹sej, economic value was 2.68×10¹⁹sej, ecological value was 1.04×10²⁰sej. And the energy monetary values of the wetland was RMB 2.12 billion, the wetland value of unit area was 453.86 million RMB per km², which was 1.16 times of the Qinghai Lake wetland value. It is very important for the East Juyan Lake wetland to recover the environment in Ejina Banner and improve the northwest ecological problems such as the salinization and desertification etc.
