It is the largest hot spring lake wetland in the Yellow River basin and the birthplace of Guanju, a famous poem in theBook of Songs. Based on field investigations and questionnaires, we valued Hechuan Wetland ecosystem services, considering use values and non-use values. The annual use value of Hechuan Wetland ecosystem services is 79.236 bilion CNY. The contingent valuation method was applied to value the annual non-use value, which is 6.27 bilion CNY. We examined how the historical and cultural value of theBook of Songs affected respondents’ willingness to pay by establishing a control group. Results suggest that historical and cultural value does have a strong inlfuence on wilingness to pay.展开更多
