摘要
应用奥德姆能值分析方法,定量分析了辽宁省双台河口湿地生态系统产品供给中的物流和能流。结果表明:辽宁双台河口湿地生态系统初级生产力能值约为1.50×1019 sej,换算成价值约为0.62亿元;能源或资源能值约为205.64×1019 sej,价值为84.31亿元。辽宁双台河口湿地产品供给货币价值总体排序为水资源>湿地水禽>水产品>底泥>湿地植被。辽宁双台河口湿地在水资源供给、湿地生物多样性保护以及水产品供给等方面的价值较高,是辽宁双台河口湿地优先保护和恢复的方向。
The emergy and material flux of Shuangtai estuary wetland ecosystem of Liaoning Province were analyzed by the theory of emergy analysis of ecological economy system established by Odum. Results showed that the solar emergy of the primary productivity of the wetland was 1.50×10^19 sej, and the corresponding value was RMB 0.62 billion. The emergy equivalent of the emergy or resources（including sediment and water） was 205.64×10^19 sej, and the corresponding value was RMB 84.31 billion. The monetary values of products supply was ranked as： water resources 〉wetland waterfowl〉 Aquatic products〉 sediment 〉wetland vegetation. The wetland displayed very high values in supply of water resources, biodiversity conservation, and supply of aquatic products, and these values should be given priority for future conservation and restoration.
