针对上海地区河岸带的环境质量提舟情况,基于条件价值法(CVM)研究上海市居民对河岸带的偏好、支付意愿及生态系统服务价值,并通过SPSS软件考察影响受访者支付意愿率的主要因素。得到以下结论:①受访者对上海地区河岸带满意度与其使用河岸带频率呈显著相关性(P=0.001)。表明受访者与河岸带的亲疏关系主要取决于其利用河岸带的实际频率。②使用五点评价法对河岸带状况进行分析,亲水性指标得分2.94。水质指标得分3.51。分别为受访者对河岸带最满意与最不满意要素。④针对河岸带1O项评价要素进行因子分析,可将受访者对河岸带的满意度因子归纳为河岸带的自然属性和社会属性,且后者的影响权重更大。④受访者对树草结合、人行道位于绿化间且护岸保留湿地的河岸带布局的评价结果得分1199,为最高得分,表明受访者偏好该类河岸带布局。⑨投标金额在一系列影响支付意愿率因子中,显著性P=0.000,影响最为剧烈。⑥受访者的支付意愿为537.6元/(年·户),整个生态系统的估算价值为2.74亿元/年。
針對上海地區河岸帶的環境質量提舟情況,基于條件價值法(CVM)研究上海市居民對河岸帶的偏好、支付意願及生態繫統服務價值,併通過SPSS軟件攷察影響受訪者支付意願率的主要因素。得到以下結論:①受訪者對上海地區河岸帶滿意度與其使用河岸帶頻率呈顯著相關性(P=0.001)。錶明受訪者與河岸帶的親疏關繫主要取決于其利用河岸帶的實際頻率。②使用五點評價法對河岸帶狀況進行分析,親水性指標得分2.94。水質指標得分3.51。分彆為受訪者對河岸帶最滿意與最不滿意要素。④針對河岸帶1O項評價要素進行因子分析,可將受訪者對河岸帶的滿意度因子歸納為河岸帶的自然屬性和社會屬性,且後者的影響權重更大。④受訪者對樹草結閤、人行道位于綠化間且護岸保留濕地的河岸帶佈跼的評價結果得分1199,為最高得分,錶明受訪者偏好該類河岸帶佈跼。⑨投標金額在一繫列影響支付意願率因子中,顯著性P=0.000,影響最為劇烈。⑥受訪者的支付意願為537.6元/(年·戶),整箇生態繫統的估算價值為2.74億元/年。

In this paper, it takes the environmental quality improvement of riparian zone in Shanghai as a case study, and tries to find out public preferences, willingness to pay (WTP) and the ecosystem service value by the contingent valuation method (CVM), and then investigates the main factors affecting WTP by SPSS. The result can be concluded as follows: Because the correlation between public preferences for Shanghai riparian zone and using frequency is significant (p = 0.001 ) , so the relationship between interviewees and riparian zone depends mainly on the riparian using frequency. Using the method of five points to evaluate the riparian zone, closeness to water and water quality are respectively 2.94 and 3.51, which are the main factors respectively satisfying and dissatisfying interviewees. Using factor analysis to evaluate the ten factors of riparian zone elements, it can be concluded that the two basic factors, that affect satisfaction are natural and social factors, and the latter affects more. The score of the preferred layout, which combines greening with grass and trees, the pavement in between and with flood prevention wall is 1 199, which means the best public choice preferred by the interviewees. The bid which is the significant factor ( p = O. 000) influences the rate of WTP most fiercely. WTP is 537.6 yuan/ (year ~ household) and the ecosystem service value is 0. 274 billion yuan/year.
