초록
Various ecosystem carry out fundamental function of material circulation and energyflow through interrelationship with many environmental factors. Therefore, it is crucial to scientificallyunderstand the value of nature to deduce correlation between environmental factor andchange of ecosystem function. In this study, we determined the accumulated ecosystem carbonand characteristics of soil respiration on grassland vegetation in Namahangang basin in NamhangangBasin. It was found that the rate of soil respiration was highly correlated with the soiltemperature 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 soillayers 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.
