Soil respiration (Rs) is considered to be a vital factor in global carbon (C) cycling,and its evaluation is an important task for estimation of C storages.We hypothesize that soil temperature and moisture play predominant roles in the seasonal and/or time variations of Rs,but on the local scale or under the same climatic conditions,other biotic and abiotic factors,such as soil organic matter (SOM),soil nutrients,soil microbial and enzyme activities,may prevail as dominant drivers of Rs.
