By employing the energy value analysis theory of ecological system, the author quantificationally analyzed and estimated the ecological benefit of Daqing marsh ecological system and the material flow and energy flow inside the system. The results showed that the value of Daqing City proper marsh was extremely great. From the table of energy value analysis, the author could come to the conclusion that the total natural resources value of Daqing marsh ecological system was 3.13 × 1010 yuan. Rainwater had an absolute advantage among all the renewable resource components, and the proportion was about 74%. The macroeconomy value of the marsh water body and the sediment
