【摘要】：為了解青島市各濕地類型生態(tài)系統(tǒng)服務(wù)價值,本文應(yīng)用Meta分析構(gòu)建青島市濕地生態(tài)系統(tǒng)服務(wù)價值轉(zhuǎn)移模型,估算了青島市各濕地類型的價值水平,并對模型的影響因素及有效性進行了探討。結(jié)果表明:構(gòu)建的青島市價值轉(zhuǎn)移模型中,污染防治成本法、生態(tài)價值法、涵養(yǎng)水源以及侵蝕控制等自變量的回歸系數(shù)為正,其對青島市濕地價值為正效應(yīng);而影子價格法、碳稅法、旅行費用法、沼澤濕地以及濕地面積的回歸系數(shù)為負(fù),其對青島市濕地價值表現(xiàn)為負(fù)效應(yīng);2012年青島市各濕地類型生態(tài)系統(tǒng)服務(wù)單位面積價值為近海與海岸濕地(3.29×10~4元·hm~(-2))河流濕地(2.38×10~4元·hm~(-2))人工濕地(2.27×10~4元·hm~(-2))沼澤濕地(1.77×10~4元·hm~(-2));與1997年相比,2012年總服務(wù)價值減少了8.01×10~8元;生態(tài)系統(tǒng)服務(wù)價值評估方法的使用、不同生態(tài)系統(tǒng)服務(wù)以及濕地面積之間的差異是影響青島市濕地生態(tài)系統(tǒng)服務(wù)價值變化的重要方面;人們的重視及保護程度、當(dāng)?shù)氐南M水平以及政府的投入是單位價值不同的主要原因;近海與海岸濕地生態(tài)系統(tǒng)服務(wù)價值的減少是濕地生態(tài)系統(tǒng)服務(wù)總價值減少的關(guān)鍵原因;Meta分析價值轉(zhuǎn)移模型的有效性檢驗結(jié)果說明,當(dāng)人力和財力資源受到制約時或當(dāng)估值數(shù)據(jù)缺乏時,其可以作為快速評估濕地生態(tài)系統(tǒng)服務(wù)價值的一種有效方法。
[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.
