Natural River And Lake Wetlands Carbon Sequestratzion Potential Evaluation And Discussion Of Carbon Sink Trade Mechanism

Global climate change, greenhouse-gas control and environmental sustainable development are most concerned about the important issues. The "12th five-year Plan" makes requirements for accelerating the change of economic growth mode and reducing greenhouse gas emissions. After Copenhagen Climate Conference, wetlands have much attention in the global carbon cycle. Increasing natural carbon sinks such as forests, grasslands, wetlands, farmland, is an effective way to reduce greenhouse gas emissions. Wetlands, grasslands and forests in Inner Mongolia are important ecological security barrier to North China. The rational use of wetland, grassland and forest carbon sinks resources in Inner Mongolia is conducive to economic development and ecological protection. At the same time, the study of natural rivers and lakes wetlands in Inner Mongolia carbon sequestration potential, and the discussion on the mechanism of carbon trade, the establishment of the carbon trading market are important to accelerate the development of China’s carbon trading, build carbon emissions trading market and develop carbon sinks trade.This paper use wetland carbon sequestration measuring and monitoring methods, combining the total area of Inner Mongolia wetland, estimated wetland organic carbon storage is6.41×1010t in Inner Mongolia. According to the carbon sequestration equtation and the area of river and lake wetland, carbon sequestration capacity of the river and lake wetlands are4.02×105t/a,3.44×105t/a.Our experimental results show that the content range of wetland soil organic carbon is0.58to12.32g/kg, the mean is5.81g/kg, the average content of soil microbial biomass carbon is15.79to160.53mg/kg, the wetland organic carbon stocks in Wuliangsuhai is4.43×105t, the mean is83.33mg/kg.We found the soil under Phragmites australis (Cav.) Trin. ex Steud vegetation communities have the highest content of soil microbial biomass carbon and organic carbon. In the wetland soil of different vegetation communities, soil microbial biomass carbon pool and organic carbon pool have the same trend. As the Phragmites australis (Cav.) Trin. ex Steud, Suaedaglauca(Bunge) Bunge, Nitraria sibirica Pall. vegetation shows a decreasing trend. Organic carbon and microbial biomass carbon reached a significant correlation (p＜0.05), Soil microbial biomass carbon stocks may reflect changes in soil organic carbon pool.We calculate Huihe degraded wetland carbon sequestration potential is0.95～9.57×109g/a, natural potential carbon sinks value of Huihe is24.89～249.68million yuan/a.Base on the development experience of domestic and international emissions trading, combine with the actual situation of China and Inner Mongolia carbon trading. We proposed the policy recommendations of the development of carbon emissions trading and the establishment of the carbon trade mechanisms. Theoretical data and policy recommendations is proposed for wetland carbon sinks basic research. The development of trading carbon sinks promote the development of low-carbon economy, rational use of natural resources. Economic development protect the ecological environment.
