Monetary Value Evaluation of Liaohe River Estuarine Wetland's Ecosystem Service Function

摘要

In order to achieve sustainable use of Liaohe River estuarine wetland ecosystems resources, this article calculated and analysed the monetary value of service functions for Liaohe River estuarine wetland. The wetland's monetary value of service functions equals to direct use value plus indirect use value and non-use value. Using method of map data visual interpretation and the classification of functional zones, we identified nine main functions of wetland ecosystem services, classified the wetland's functional zones. And the monetary value is calculated based on the functional zones with map data after visual interpretation. Conclusions can be made that the ecosystem service function's monetary value of Liaohe River estuarine wetland is a large amount, increasingly awareness on scientific conservation and development of resources should be taken into account.
