| 摘 要： | 利用中巴资源卫星对辽河三角洲盘锦湿地类型进行调查的基础上,综合应用环境经济学、资源经济学等方法对辽河三角洲湿地生态系统的服务功能价值进行了评估,得出该区域湿地生态系统的服务功能总价值为90.243×108元RMB.休闲娱乐、大气组分调节、物质生产和水文调节是该区域湿地生态系统服务功能价值的主要贡献者,分别占到系统总服务功能价值的25.93%、25.03%、22.35%和20.44%.

| Abstract: | The main Liaohe River Delta is a wetland ecosystem, including the reef swamp, paddy field, mud flat, river, crab and shrimp field, barren mud and met meadow act surveyed by the remote sensing images of China-Brazil resource satellite. The evaluation on the main services in the wetland ecosystem of Liaohe River Delta was done by methods of environmental economics, resource economics, engineer building value and tour value. The total value in the wetland ecosystem services of Liaohe River Delta is about 90.243×108RMB. Among these services, the order of service value is: material output > air ingredients control > leisure service > flood control > habituating protection > culture service > pollution purification, with contribution of 25.93, 25.03, 22.35, 20.44, 3.17, 1.71 and 1.37%, respectively. |
