Abstract:Taking Minjiang estuary wetland as a case study, which is an important post on the migration route of migratory bird from Eastern Asia to Australasia. The contingent valuation method (CVM) was used in this paper to evaluate the non-use value of the wetland. 500 payment card CVM questionnaires were distributed and 482 were fed back as useful questionnaires. On the basis of the questionnaires, the mean willingness to pay (WTP) and the median to the wetland ecosystem were calculated. Which were 151.16 yuan(RMB) and 56.36 yuan(RMB) per person every year in future 5 years. The relative frequency distribution curve of the WTP was a monotonically decreasing distribution curve. Taking research purpose into account, mean WTP was adopted to evaluated the non-use value of the wetland, which was 5.01×108 yuan(RMB) per year. The impacts of factors on WTP were also analyzed by Spearmans rank correlation coefficient, which showed that WTP was related to income, educational level, age, gender, and profession of the respondents.
