摘要
城市湖泊湿地资源的非使用价值评价,不仅可为建立区域生态账户提供基础数据,还可促进政府加大城市湖泊湿地保护与治理投资力度。以武汉市典型城市湖泊为研究对象,基于条件价值评估法对城市湖泊湿地资源的非使用价值进行了货币化计量。结果表明,88.2%受访者认为武汉市城市湖泊湿地的非使用价值很重要,但41.2%受访者对武汉市城市湖泊湿地的环境质量变化情况不了解:受访者认为湖泊湿地非使用价值3种组分的重要性程度顺序为存在价值>遗产价值>选择价值。受访者对武汉市典型城市湖泊严东湖、东湖、紫阳湖的支付意愿率分别为70.8%、70.1%、56.9%,人均支付意愿值分别为48.4元·a-1、49.6元·a-1、44.0元·a-1,非使用价值分别为2.84×108元·a-1、2.88×108元·a-1、2.07×108元·a-1,呈现出半自然湖泊>自然湖泊>人工湖泊的趋势。受访者年龄、年收入、文化程度对支付意愿有显著影响,而性别、职业、职称对支付意愿无显著影响;受访者年收入、文化程度、职称对支付值有显著影响,而性别、年龄、职业对支付值无显著影响。
Evaluation on non-use values of urban lake wetlands,not only provide the basic data for the establishment of regional ecological accounts,but also enlarge the strength of conservation and governance investment of urban lakes of government departments.The contingent valuation method（CVM） was used in this paper to evaluate the non-use value of the typical lakes in Wuhan.The results indicated that 88.2% of the respondents thought that it was very important for the non-use values of urban lakes,that 41.2% of the respondents were not aware of the environmental changes of urban lakes in Wuhan,and that the importance of the degree of the three components of non-use values was existence value heritage value option value.Furthermore,the rate of willingness to pay（WTP） for Yandong lake、East lake、Ziyang lake was 70.8%,70.1%,56.9%,the mean WTP per person was 48.4 yuan·a-1,49.6 yuan·a-1,and 44.0 yuan·a-1,and the non-use values was 284million yuan·a-1,288 million yuan·a-1and 207 million yuan·a-1,respectively,the shown trend was semi-natural lake natural lake artificial lake.The impact analysis of total samples factors on WTP showed that age,annual income,educational level were correlated remarkably with WTP,while gender,profession,professional title were not.In addition,annual income,education level and professional title were also correlated remarkably with WTP value,however,gender,age,profession also weren＇t.
