Effect of soil temperature and soil moisture on soil respiration of ungrazed grassland in Loess Plateau,Gansu

摘要：

Soil respiration (SR) is a major component of greenhouse gas emission and is a crucial pathway of the C cycle.The potential increase of SR caused by global warming may present a positive feedback effect on atmospheric CO2 and climate change (Kirschbaum,1995).However, the factors that control the exchange of CO2 between soil and atmosphere in Loess Plateau, Gansu are not well understood.The results in this paper represent a preliminary exercise in studying SR variations and its correlation with soil temperature ( Ts) and soil moisture (Ms).
