Abstract:The contingent valuation method (CVM) was used to evaluate the nonuse value of the Hongze Lake’s biodiversity. The nonuse value includes option value, bequest value and existence value. The study was based on a survey in which 520 questionnaires was distributed in the three counties: Hongze, Xuyi, and Sihong and 484 were return as valid ones. The statistical results showed that the non-use value of biodiversity was 2.14 million RMB per year which was about 4.35% of the total GDP of the three counties in 2007. The willingness to pay (WTP) of the respondents decreased with the increase of ages, and went up with the increase of income. At the same time, it playd an important role in improving WTP for respondents to improve their environmental consciousness and their belief in the enforcement of environmental policies. The higher the environmental consciousness was, the more they were willing to pay. The more confident on the policy enforcement, the more they were willing to pay.
