| 摘 要： | 应用H.T.Odum创立的生态经济系统能值分析的理论和方法,对凌河口湿地生态经济系统价值进行科学的定量评估。评估结果:生态服务以及水产方面货币价值较大,经济效益显著,能值分别为1.001×1021 sej和4.349×1018 sej,货币价值为4.094×109美元和1.709×107美元。能值分析结果表明,应重点关注水产资源的合理建设及将生态服务效应的保护利用放在首位,为保护经济和生态环境可持续发展提供了价值参考。此外,保护凌河口湿地应注重生态系统整体性,使之向良好稳定的方向发展。

| Abstract: | In this paper,the ecological and economic value analysis theory and methods established by HTOdum are used to evaluate emergy-emdollar value of the Linghe River Estuarine Wetland.The results show that the benefits of the ecosystem service functions of function service and fisheries are significant.The emergy values are 1.001×1021 sej and 4.349×1018 sej,the emdollar values are 4.094×109 USD and 1.709×107USD.Emergy analysis shows that the development and utilization of the Linghe River Estuarine Wetland Resources should be protected and restored under the premise of fisheries rational construction.In this context,we can coordinate the ecological function between the elements of dynamic balance,dual stage estuarine wetlands for sustainable development. |
