摘要：以辽宁省鸭绿江口湿地为研究对象,应用双分界二分式(double-bounded dichotomous)条件价值方法(contingent valuation method,CVM),对该保护区生物多样性维持价值进行定量评价。采用面访调查为主、网上调查为辅的方式,进行支付意愿问卷调查;利用支付意愿函数影响因素模型,构建了双分界二分式条件价值评估法数据分析模型,建立以受访者社会、经济属性(性别、年龄、收入、教育背景和职业)为变量的支付意愿函数。研究结果表明,2015年,鸭绿江口湿地生物多样性维持价值为46.45×108元/a,人均愿意支付金额为133.35元/a;随着年龄、教育程度和收入水平的提高,受访者愿意为维持鸭绿江口湿地生物多样性的支付金额在增加;女性的愿意支付金额略高于男性;学生、军人、国家机关(事业单位)和离退休人员的愿意支付率相对较高,而农、林、牧、渔生产人员的愿意支付率最低。
This paper conducted a quantitative evaluation on the biodiversity maintenance value of the typical coastal wetlands--Yalu River Estuary Wetlands in Liaoning province by applying the double-bounded dichoto- mous contingent valuation method （CVM）. We looked into the respondents＇ Willing To Pay （WTP） mainly based on the interview and supplemented by the online survey, aiming to evaluate the biodiversity maintenance value of Yalu River estuarine wetlands and identify what factors influences respondents＇ WTP. The influencing factor model of WTP was applied to build the double-bounded dichotomous CVM model including social and economic attributes （gender, age, income, education, job）, and the parameter regression model of analysis was used to establish the influential factor analysis model of WTP. The results indicated that the total biodiversity maintenance value of Yalu River estuarine wetlands was 46.45 × 108 yuan/yr in 2015; the average WTP was 133.35 yuan/yr. The respondents＇ WTP increased with age, education and income, and the women＇ WTP value was a little higher than that of men＇ s. The payment ratios for students, military and who worked on government offices and public institution, retired people were relatively higher; however, the payment ratio for the respon- dents who worked on production （agriculture, forestry, animal husbandry and fishery） was the minimum.
