Comparison of CO₂ Net Exchange between Different Plant Communities in Typical Steppe of Inner Mongolia Plateau

Abstract:

To measure the carbon exchange of two different plant communities in typical steppe, we used dynamic chamber method improved from static chamber method, and compared it with the regional eddy-covariance method. Results showed that: 1) Biomass of plant community with enclosed restoration was higher than that with free grazing; 2) After 6 years enclosed restoration, the plant community had become a CO2 sink though the region was still a CO2 source while the free grazing plant community had turned into a CO2 source in contrast with its regional CO2 sink, and 3) Net ecosystem exchange (NEE) of enclosed restoration plant community was significantly higher than that of typical steppe.
