吉林省湿地生态系统服务价值评估

为科学评估吉林省湿地生态系统最终服务价值,在遥感调查和实地调查的基础上,综合运用生态经济学方法,针对吉林省湿地特点建立吉林省湿地生态系统服务价值指标体系和方法体系,以小班为单位估算吉林省湿地生态系统服务价值。结果显示,吉林省湿地生态系统服务总价值为2 161.93亿元,湿地提供的平均价值为12.71万元/hm~2,其中供给服务功能的价值为436.46亿元,占总价值的20.19%,调节服务功能价值为1 116.64亿元,占总价值的51.65%,支持服务功能价值为417.64亿元,占总价值的19.32%,文化服务功能价值为191.19亿元,占总价值的8.84%,反映出吉林省湿地在发挥直接经济效益的同时,还兼具巨大的生态效益和社会效益。

Evaluation of wetland ecosystem services in Jilin Province

In order to scientifically evaluate the final service value of wetland ecosystem in Jilin Province, based on the remote sensing surveys and field investigations, the index system framework and methods for evaluating the serving functions and value of wetland ecosystem are established with an integrated use of comprehensively applying resource economics and ecological economics methods, and then the service value of the wetland ecosystem in Jilin Province is evaluated by means of various items. The results show that the total service value of wetland ecosystem in Jilin Province is quantitatively estimated at 216. 193 billion CNY, with the average value of 0. 12 million CNY·hm^-2. The supplying service function value is 43. 646 billion CNY, accounting for 20. 19% of the total value. The regulating service function value is 111. 664 billion CNY, accounting for 51. 65% of the total value. The supporting service function value is 41. 764 billion CNY, accounting for 19. 32% of the total value. The cultural service function value is 191. 19 billion CNY, accounting for 8. 84% of the total value.
