和田地区湿地生态系统服务功能价值评估研究

以和田地区湿地为研究对象,建立和田地区湿地生态系统服务功能评估指标体系,采用市场价值法、影子工程法、碳税法,工业制氧法和替代法等对和田地区湿地的资源供给、调节服务、支持服务及科研文化服务4大类功能11项评估指标进行评估。结果表明:和田地区湿地生态系统服务功能总价值为1 787 153.92×10~4元·a~(-1),其中价值量最大的为调节服务功能,价值843 317.18×10~4元·a~(-1),占总价值的47.19%;最小的为资源供给服务,价值119 122.13×10~4元·a~(-1),占6.67%;支持服务功能和科研文化服务功能价值分别为691 376.11×10~4元·a~(-1)和133 338.50×10~4元·a~(-1),分别占38.69%和7.46%。所评估的11项指标中,涵养水源与调蓄洪水功能价值最大,为448 224.43×10~4元·a~(-1),占总价值的25.08%;降解污染功能价值最小,为970.99×10~4元·a~(-1),占0.06%。

Evaluation on Service Value of Wetland in Hotan Region

Index appraisal of resource appraisal for ecosystem service were established based on the structure and ec-ological proceeding of wetland ecosystem of Hotan region.Eleven evaluation indices of four kinds of function (re-source supply,regulation service,support service & scientific culture)were conducted evaluated by using marketing value method,shadow engineering method,carbon tax method,industrial oxygen producing method and substitution method.Result shows that the total service value of wetland ecosystem in Hotan Region is 1 787 153.92×104 Yuan RMB per year,in which regulation service value is the biggest,843 317.18×104 Yuan RMB per year,accounted for 47.19%.Resource supply is the smallest,119 122.13×104 Yuan RMB per year,accounted for 6.67%.The func-tion of support service and culture service is 691 376.11×104 yuan RMB per year & 133 338.50×104 Yuan RMB per year,respectively,accounted for 38.69% & 7.46% respectively.Among the 11 kind of evaluation indices,serv-ice value of water conservation and flood regulation are the biggest,being 448 224.43×104 Yuan RMB per year,ac-counted for 25.08%;when pollution degradation is the smallest,970.99×104 Yuan RMB per year,accounted for 0.06%.Wetland in Hotan region is very important to the People’s life and development of social economy in that re-gion,this study provides the scientific basis for use and management of wetland resources in Hotan Region.
