摘　　要：为了提高西汉(西安—汉中)高速公路沿线秦岭山区生态环境保护经济决策和政策制定的科学性,借助条件价值评估法(CVM),采用投标卡的方式,调查了沿线居民保护生态环境的支付意愿,并对调查样本支付意愿与社会经济因素之间的相关关系进行了多元线性回归分析。结果表明:西汉高速公路沿线有79.8%的居民家庭存在保护生态环境的支付意愿,在未来5 a平均每年每户愿意支付138.18元,而保护西汉高速公路沿线秦岭生态环境的总经济价值至少不低于17 353 921元;居民最大支付意愿的数额与其受教育程度、家庭年收入和职业显著相关。In order to provide more scientific evidences for the economic decision and policy framing of protecting the ecological environment of Qinling mountains along Xi＇an-Hanzhong expressway, this paper used Contingent Valuation Method（CVM） to investigate the households＇ willingness to pay（WTP） for the environment protection through the way of payment card, analyzed the correlativity between WTP and related social and econimic factors by linear multiregression model. The results show that 79. 8% of the households along Xi＇an-Hanzhong expressway would like to pay for the environment protection and the value of WTP in next 5 years is 138.18 RMB Yuan per household per annual, and the total economic value of protecting the ecological environment of Qinling mountains along Xi＇an-Hanzhong expressway is not less than 17 353 921 RMB Yuan; the households＇ WTP has marked correlation with their education level, household＇s income and profession. 4 tabs, 1 fig, 6 refs.
