[Abstract]:Baiyangdian wetland is the largest freshwater wetland in North China Plain. The value assessment of Baiyangdian wetland ecosystem final ecosystem services can reveal the direct contribution of Baiyangdian wetland ecosystem to beneficiaries of different scales with intuitive economic data. Based on the analysis of ecological characteristics and beneficiaries of Baiyangdian wetland, the final service value evaluation index system of Baiyangdian wetland ecosystem was established. On the basis of the available data in 2011, the method of market value is used synthetically to replace the cost method. The economic value of Baiyangdian wetland was evaluated by individual travel cost model method and payment card conditional value method. The results showed that in 2011, the total value of ecosystem service of Baiyangdian wetland was 35.55 脳 10 ~ 8 yuan. Of these, flood regulation and recreation are the leading services provided by Baiyangdian. The final ecosystem services assessed are ranked by value. The order is regulating flood, recreation, recreation, fresh water, raw material production, non-use value, water supply, oxygen, sequestration, and carbon sequestration. The evaluation results comprehensively reflect the direct contribution of Baiyangdian wetland to the beneficiaries. It not only improves the awareness of the management and the beneficiaries of wetland protection, but also provides an important data basis for the management to determine the ecological compensation standard of Baiyangdian wetland. The evaluation index is to distinguish the intermediate service and final service of Baiyangdian wetland ecosystem, construct the monitoring index system of Baiyangdian wetland ecosystem service, and carry out the dynamic evaluation of the final service of Baiyangdian wetland ecosystem. Tradeoff analysis and driving factor research provide an important direction for the development of wetland ecosystem services from static assessment to optimal management of wetland ecosystem services.
