Abstract

Abstract: As one of the most important ecosystem types of the global land surface, wetlands play an increasingly important role in maintaining biodiversity. In order to improve the protection of wetlands, Contingent Valuation Method (CVM), a worldwide mature method for evaluating the economic value of ecosystem services, was employed and applied to evaluate biodiversity maintenance value in the Jilin wetlands. A total of 500 CVM questionnaires of payment card were sent out by integrating the local and network survey methods, and 491 usable questionnaires were received. The results showed that the willingness to pay (WTP) per capita of Jilin wetlands was 120.7 RMB per year in 2012. According to the total population of China and Jilin Province, the biodiversity maintenance values of Jilin wetlands were 100.51 and 2.08 billion RMB, respectively. The education level, income level and degree of concern for wetland biodiversity were significantly correlated with WTP (P<0.05), while the sex and age had no effects on WTP. The investigation way and distance also significantly affected WTP (P<0.0001). To better protect the biodiversity of Jilin wetlands, government managers should intensify propaganda and enhance the environmental protection consciousness of the public. This study makes it possible to contrast the cost of wetland protection and the value of exploitation, which will help the government and decision makers to make reasonable protection policy. Our results also have important significance in making reasonable decisions for regional ecological protection and economic development, which will be helpful for protecting and restoring wetland ecosystem in the future.
