【摘要】：利用条件价值法(contingent valuation method,CVM),评估了洞庭湖的非使用价值。于2012年和2014年,在洞庭湖区,通过面对面调研的形式,进行问卷调查。研究结果表明,洞庭湖区居民支付愿意率为60.24%,人均支付意愿(willingness to pay,WTP)值为14.12元/(月·人);2013年,洞庭湖生态系统的非使用价值为16.06×108元,其中,洞庭湖的存在价值最大,其它依次为遗产价值、选择价值;受访者不愿意支付洞庭湖生态系统的主要有两个原因,其一是他们认为生态保护的费用应该由政府或旅游企业支付,其二是他们的收入有限;受访者的年龄和教育程度对支付意愿有显著影响,21~30岁年龄段且学历较高者的支付意愿较强;性别对支付意愿值有显著影响,男性支付意愿值较高;研究同时表明,在建设洞庭湖生态经济区的过程中,政府应该对居民最为关注的水质、水量等问题予以重视,同时加强宣传教育,提高居民的生态环境保护意识。
[Abstract]:The non-use value of Dongting Lake was evaluated by using conditional value method (contingent valuation method,CVM). In 2012 and 2014, questionnaires were conducted in Dongting Lake District by means of face-to-face surveys. The results show that the willingness rate of residents in Dongting Lake region is 60.24, and the per capita willingness to pay (willingness to pay,WTP) is 14.12 yuan per month. In 2013, the non-use value of Dongting Lake ecosystem is 16.06 脳 108 yuan, among which, the existence value of Dongting Lake is the largest, the other is heritage value, selection value; Respondents were reluctant to pay for the Dongting Lake ecosystem for two main reasons: one was that the cost of ecological protection should be paid by the government or tourism enterprises, and the other was their limited income; The age and educational level of the interviewees had a significant influence on the willingness to pay, while those aged 21 to 30 years with higher education had a stronger willingness to pay, while gender had a significant effect on the willingness to pay, while the male had a higher willingness to pay. The study also shows that in the process of constructing ecological economic zone of Dongting Lake, the government should pay attention to the problems of water quality and water quantity that the residents pay most attention to, at the same time, strengthen propaganda and education, and improve the ecological environmental protection consciousness of residents.
