Various ecosystem carry out fundamental function of material circulation and energy flow through interrelationship with many environmental factors. Therefore, it is crucial to scientifically understand the value of nature to deduce correlation between environmental factor and change of ecosystem function. In this study, we determined the accumulated ecosystem carbon and characteristics of soil respiration on grassland vegetation in Namahangang basin in Namhangang Basin. It was found that the rate of soil respiration was highly correlated with the soil temperature in all communities. The measured soil respiration rates were 1,539 mgCO2 m-2 h-1, 1,200 mgCO2 m-2 h-1, 1,215 mgCO2 m-2 h-1 in Miscanthus sacchariflorus, Phragmites japonica, Salix koreensis communities, respectively. Also, carbon quantities accumulated in litter and soil layers were 40.6 tCha-1 (1.9+38.7), 46.9 tCha-1 (43.0+3.9), 31.2 tCha-1 (28.9+2.3) in M. sacchariflorus, P. japonica, S. koreensis communities, respectively.
