Ecosystem Service Function Evaluation of Honghu Lake Wetland, China

Honghu Lake is the biggest lake of Hubei Province and the wetland resources are extremely rich. Based on Honghu Lake's features, this paper uses the theories and methods of resource economics and eco-economics to evaluate the ecosystem service function value of Honghu Lake from the aspects of resources function, environment function and social function. The conclusion shows that Honghu Lake's ecology service value is 2.8063 billion RMB Yuan. Among them, the biological resources value is 1.0734 billion RMB Yuan which accounts for 38% of the total value, and the value from storing and regulating flood is 1.0382 billion RMB Yuan, 37% of the total. The results indicate that the Honghu Lake wetland ecosystem service function value mainly lies in providing aquatic products and storing and regulating flood. Therefore, only when the Honghu Lake's ecological environment and the wetland ecosystem are restored and protected, the lake's sustainable development economy could be guaranteed.
