| 中文摘要 | high levels of available nitrogen (n) and carbon (c) have the potential to increase soil n and c mineralization we hypothesized that with an external labile c or n supply alpine meadow soil will have a significantly higher c mineralization potential and that temperature sensitivity of c mineralization will increase to test the hypotheses an incubation experiment was conducted with two doses of n or c supply at temperature of 5 15 and 25 c results showed external n supply had no significant effect on co(2) emission however external c supply increased co(2) emission temperature coefficient (q(10)) ranged from 113 to 1 29 significantly higher values were measured with c than with n addition and control treatment temperature dependence of c mineralization was well-represented by exponential functions under the control co(2) efflux rate was 425 g co(2)-cm(-2) year(-1) comparable to the in situ measurement of 422 g co(2)-cm(-2) year(-1) we demonstrated if n is disregarded microbial decomposition is primarily limited by lack of labile c it is predicted that labile c supply would further increase co(2) efflux from the alpine meadow soil (c) 2010 elsevier masson sas all rights reserved |
