Abstract: As its abundant carbon storage, wetland ecosystem plays an important role in slowing down global climate warming. Taking Zhalong wetland as an example, the carbon sequestration values of both plant and soil were assessed, based on Carnegie-Ames-Stanford Approach model (CASA). The results showed that the total value of carbon sequestration of Zhalong wetland was 0.98 billion Yuan in 2011, of which 0.24 billion Yuan for plant, and 0.74 billion Yuan for soil. The carbon sequestration value of marsh per unit area was the largest in all kinds of landscape types, being 5993.4 Yuan per hectare, followed by meadow, cultivated land, other types and open waters. Carbon sequestration value of Zhalong wetland was higher in the center than in periphery areas. Protecting and restoring the marshes of Zhalong wetland would have a positive influence on its carbon sequestration ability.
