The wetland is a unique natural complex of land and water interact to form the outline, wetlands, forests, oceans, the World Conservation Union (IUCN), the United Nations Environment Programme (UNDP) and the World Wide Fund for Nature (WWF) prepared by the World Conservation of Nature with the three global ecosystem. Ramsar Convention wetland is defined as: \salt water. including low tide water depth does not exceed six meters \Wetlands and human survival, reproduction, and development are closely related, not only to provide a variety of resources for the production of human life, and has a huge environmental features and benefits, known as the \one of the landscape and the most important human living environment, especially in against floods, runoff regulation, flood storage and drought prevention and control of pollution, climate regulation, soil erosion control, siltation epeirogenic, landscaping has an irreplaceable role in other systems in today's global environment are strongly damaged, increasing scarcity of resources, its powerful ecological functions, abundant natural resources gradually attracted worldwide attention. Enormous ecological value of wetlands is often ignored, important reasons lead to over-exploitation and loss of wetland resources, wetland ecological value estimate is to carry out the important basis of the protection and sustainable use of wetland resources. In this study, the typical peat bog is located in the northeast of China, Changbai Mountain area, for example, the estimated value of Longwan Nature Reserve the Jinchuan peat swamp wetland ecosystem within and analysis based on emergy theory and methods. Dimensionless value is a measure of value, the material foundation of natural ecosystems as ecological capital input of capital, in accordance with the form of capital formation and distribution process is divided into three parts of fixed capital and goods output. : Jinchuan peat bog annual input of capital of 1.59 × 1017sej, valued at approximately $ 30,010; the Fixed Capital 1.57 × 1020sej, value of approximately U.S. $ 29,635,380 (including peat accounted for 99.18%); the annual physical outputs of × 1017sej 3.04, the value of about $ 57,340. The results show that the peat wetlands bears is the most important part of the wetland, which is the basis of the process of the various functions of wetlands, must be subject to special protection because of its non-updatable and irreplaceable.
