基于Meta分析的青岛市湿地生态系统服务价值评估
Ecosystem services assessment of wetlands in Qingdao based on meta-analysis
摘要
Abstract
To investigate the ecosystem service values of various wetland types in Qingdao,this paper used meta-analysis to estimate the ecosystem service value levels of various wetland types on the basis of wetland ecosystem service value transfer model,and explored the influence factors and effectiveness of the model.The results showed that the regression coefficients of independent variables such as pollution prevention method,cost control method,ecological value method,water conservation,and erosion control were positive,which had positive effects on wetland value in Qingdao.However,the regression coefficients of independent variables such as shadow price method,carbon tax method,travel cost method,marshes,and wetlands area were negative,which had negative effects on wetland value.The values of various wetland types were in order of onshore and offshore wetland (3.29x 104 yuan · hm-2) ＞ river wetland (2.38x 104 yuan · hm-2) ＞ constructed wetland (2.27x104yuan · hm-2) ＞ swamp wetland (1.77x104 yuan · hm-2).Compared with 1997,the value of wetland ecosystem services decreased by 0.801 billion yuan in Qingdao in 2012.The results indicated that the evaluation methods of the ecosystem service value,different ecosystem services,and the wetland area were the important aspects affecting the wetland ecosystem service value.Ecosystem service values of different types of wetland were different in Qingdao.People's attention and protection effort,local consumption level and government investment were the main reason affecting wetland ecosystem service value per area unit.Compared with 1997,the reduction of offshore and coastal wetland ecosystem service value was the main reason for the decreased wetland ecosystem service value in Qingdao in 2012.Our results indicated that meta-analysis was a feasible method to evaluate wetland ecosystem service value when human and financial resources were restricted or valuation data was lacking.关键词
