【摘要】：为了解青岛市各湿地类型生态系统服务价值,本文应用Meta分析构建青岛市湿地生态系统服务价值转移模型,估算了青岛市各湿地类型的价值水平,并对模型的影响因素及有效性进行了探讨。结果表明:构建的青岛市价值转移模型中,污染防治成本法、生态价值法、涵养水源以及侵蚀控制等自变量的回归系数为正,其对青岛市湿地价值为正效应;而影子价格法、碳税法、旅行费用法、沼泽湿地以及湿地面积的回归系数为负,其对青岛市湿地价值表现为负效应;2012年青岛市各湿地类型生态系统服务单位面积价值为近海与海岸湿地(3.29×10~4元·hm~(-2))河流湿地(2.38×10~4元·hm~(-2))人工湿地(2.27×10~4元·hm~(-2))沼泽湿地(1.77×10~4元·hm~(-2));与1997年相比,2012年总服务价值减少了8.01×10~8元;生态系统服务价值评估方法的使用、不同生态系统服务以及湿地面积之间的差异是影响青岛市湿地生态系统服务价值变化的重要方面;人们的重视及保护程度、当地的消费水平以及政府的投入是单位价值不同的主要原因;近海与海岸湿地生态系统服务价值的减少是湿地生态系统服务总价值减少的关键原因;Meta分析价值转移模型的有效性检验结果说明,当人力和财力资源受到制约时或当估值数据缺乏时,其可以作为快速评估湿地生态系统服务价值的一种有效方法。
[Abstract]:In order to understand the ecosystem service value of various wetland types in Qingdao, this paper uses Meta analysis to construct the service value transfer model of wetland ecosystem in Qingdao, and estimates the value level of each wetland type in Qingdao. The influencing factors and validity of the model are also discussed. The results showed that the regression coefficients of independent variables, such as pollution prevention cost method, ecological value method, water conservation and erosion control, were positive, and the value of Qingdao wetland was positive. However, the regression coefficient of shadow pricing method, carbon tax law, travel cost method, swamp wetland and wetland area is negative, which has negative effect on wetland value in Qingdao. In 2012, the value of ecosystem services per unit area of wetland types in Qingdao was offshore and coastal wetland (3.29 脳 10 ~ (4) hm~ (-2), river wetland (2.38 脳 10 ~ (4) yuan hm~ (-2) and constructed wetland (2.27 脳 10 ~ (4) hm~) (P < 0.05). -2) marsh wetland (1.77 脳 10 ~ (4) hm~ (-2);) Compared with 1997, the total service value decreased by 8.01 脳 10 ~ (8) yuan in 2012; The use of ecosystem service value assessment method, the difference between different ecosystem services and wetland area are the important aspects that affect the change of wetland ecosystem service value in Qingdao. The main reasons for the difference of unit value are the degree of attention and protection, the local consumption level and the input of the government, and the decrease of service value of coastal wetland ecosystem is the key reason for the decrease of the total value of wetland ecosystem service. The validity test results of Meta value transfer model show that it can be used as an effective method to evaluate the value of wetland ecosystem services quickly when human and financial resources are restricted or when the valuation data are scarce.
