【摘要】：生态系统服务价值评估是环境管理政策制定的决策基础。选择实验法通过个体支付意愿对非市场物品进行价值评估,其有效性和可靠性是学者们非常重视的问题。本文以三江平原湿地为例,构建基于计划行为理论的湿地生态系统服务支付意愿评估方法,探讨受访者对湿地生态系统服务功能支付意愿潜在动机,提高仅包含社会经济信息参数的传统选择实验(Choice Experiments,CE)研究结果的可靠性及科学性。通过对湿地生态系统服务效用函数选取不同的多项Logit模型进行拟合,实证分析了受访者对湿地面积、生物多样性、水源涵养和自然景观等四个生态系统服务属性的支付意愿及其影响因素。结果表明:(1)居民对于湿地生态系统服务功能偏好由高到低分别为水源涵养、湿地面积、自然景观和生物多样性;(2)模型检验结果表明,引入行为态度、主观规范以及知觉行为控制变量后的多项Logit模型拟合程度表现更优,能更好地解释受访者的选择行为;(3)各生态系统服务功能属性的边际价格分别为:为了在未来实现三江平原生态系统服务功能各指标预设目标,为改善水源涵养意愿支付的成本为98.92元/(人·a);为维持现有湿地面积意愿支付的成本为58.90/(人·a);为改善自然景观意愿支付成本为54.09元/(人·a);为提高生物多样性意愿支付的成本为46.06元/(人·a)。
[Abstract]:The evaluation of ecosystem service value is the basis for decision of environmental management policies. Choose the experimental method to assess the value of non market goods through individual willingness to pay, the validity and reliability of scholars is a very important issue. This paper takes Sanjiang plain wetland as an example, will pay service evaluation method of Gou Jianji in the theory of planned behavior of wetland ecosystem to investigate, the respondents to the wetland ecosystem service function of willingness to pay potential motivation, improve the traditional selection experiment contains only the information of social economic parameters (Choice Experiments, CE) and the reliability of scientific research results. The wetland ecosystem service utility function to select a number of different Logit models by fitting the empirical analysis of the respondents of the wetland area, biodiversity, willingness to pay for water conservation and natural landscape four ecosystem service attributes and its influence Factors. The results showed that: (1) for the residents of the wetland ecosystem services preference from high to low are water conservation, wetland area, natural landscape and biological diversity; (2) model test results show that the introduction of behavioral attitude, the fitting degree of the multinomial Logit model performance variables after better subjective norms and perceived control the behavior, can better explain the choice behavior of the respondents; (3) the marginal price of ecosystem service function attributes respectively: in order to achieve in the future, the index of ecological system in Sanjiang plain, the service function of the default target, to improve water conservation willingness to pay for the cost of 98.92 yuan / (- a); to maintain the cost of wetland area the willingness to pay for 58.90/ (human a); to improve the natural landscape of the willingness to pay the cost of 54.09 yuan / (- a); to improve the biodiversity of the willingness to pay for the cost of 46.06 yuan / (- a).
