天津滨海新区围填海工程对海洋生态系统服务功能价值的损失评估

Loss Appraisal on Sea Reclamation Project to Marine Ecosystem Service Function Value in Binhai New Area of Tianjin

利用市场价格法、影子工程法、替代成本法、成果参照法等构建了围填海对海洋生态系统服务功能价值损失评估模型,并对2012年天津滨海新区围填海造成的海洋生态系统服务功能价值损失进行了定量评估。结果表明,2012年天津滨海新区围填海造成的海洋生态系统服务功能价值损失总值为7 182.88万元,单位面积损失为447.25万元/(km^2·a)。其中供给服务功能价值损失最大,占价值损失总量的51.94%,其次为调节服务功能,占18.39%;支持服务功能价值损失位居第三,占14.87%;文化服务功能价值损失最小,占14.80%。研究结果与实际情况相差较小,可为围填海形成后的生态恢复和补偿经费提供依据。

A model is established for loss appraisal on sea reclamation to marine ecosystem service function value by using market value method,shade project method,alternative cost method and outcome reference method,and the loss of marine ecosystem service function value caused by the sea reclamation projects in Binhai New Area of Tianjin in 2012 is quantitatively estimated.The results have shown that the loss of the sea reclamation to the marine ecosystem service function value in Binhai New Area of Tianjin in 2012 was totally RMB 71.828 8million yuan/a,with the loss per unit area being RMB 4.472 5million yuan/(km^2·a).Among them,the loss of supply service function value was the biggest,making up 51.94% of the total.Next was the loss of regulating service function value,making up 18.39% of the total.The third was the loss of support service function value,making up 14.87% of the total.The minimal loss was the value of cultural service function,making up about 14.80%of the total.The results of the study do not differ a lot from the actual situation and can provide references for the ecological restoration and compensation funds after the sea reclamation project.
