Soil respiration is a major process of carbon dioxide emission from terrestrial ecosystems to atmosphere. Researches on spatiotemporal patterns of soil respiration could be helpful to the construction of a quantitative evaluation model of soil respiration at regional scale, and also, could improve our predictive ability of carbon balance status under future climate change of typical ecosystems at regional or global scale. This paper integrated the main research results about the soil respiration at regional scale in China, analyzed the statistical characteristics and regional difference of temperature sensitivity and soil respiration, and in addition, the quantitative evaluation on the spatiotemporal distribution and its effects on the carbon balance at China’s even global scale was also given in this paper. The results showed that Q10 of forest ecosystem was the highest, followed by that of farmland ecosystem, and Q10 of grassland ecosystem was lowest, indicating that Q10 was higher while air temperature was lower. Also, Q10 of terrestrial ecosystem in China was lower than that of other countries. Rs displayed a significant seasonal variation. Rs of different ecosystems presented a similar changing trend with Q10. There was seasonal dynamics of monthly Rs along latitude and longitude gradients. Additionally, the seasonal amplitude of Rs increased with increasing longitude. Between 1995 and 2004, the Rs in China, with an average value of 3.84 Pg C·a-1, contributed 4.87% to the global soil CO2 emission.
