[Method] Questionnaire was designed according to the Contingent Valuation Method (CVM) to investigate people of different occupations at different ages, based on which the evaluation on non-use value of Dianchi lake wetland was carried out. And the relationship between WTP and social characteristics were analyzed by using non- parametric estimation. [Result] The average WTP on Dianchi lake wetland is 150.03- 217.66 yuan per person every year, and the total WTP is 626-909 million yuan ev- ery year. Age, education and residence of the respondents have remarkable influ- ence on the VVTP. The influence of education level and residence on option value is significant; bequest value is significantly correlated with age; while there is no significant relationship between existence value and social characteristics. [Conclusion] The evaluation on the non-use value of Dianchi lake wetland is important for the scientific development and utilization of wetland resources.展开更多

The results showed that the area of wetland and plant community account for 92.2% in lakeside zone, the increase was 141.4% compared with the value of 2007. The total value of evaluated benefi ts of Dianchi wetland increased 3.439 billion yuan, and ecological environment improved gradually.展开更多
