| 英文摘要 | Microbial activity is rapidly reduced due to the decrease in temperature, but does not completely cease in the cold season. The snowpack in late winter insulates the soil and further increases soil temperature, allowing microbes to remain active and inducing a shift in the nature of N processing in alpine areas. Microbes need both carbon (C) and nitrogen (N) for their growth and metabolism and the scarcity of either will limit their activity. So soil available N pools and N cycling were closely linked to the C and N of the soil. Many previous studies showed the different results in different regions. Some of the results were considered to be C limited, some considered to be N limited, and also some considered to have little impact. However, which factor limited soil microbes and controlled soil N mineralization was not clear in the alpine belt of the eastern Qinghai Tibet Plateau. In present study, the effects of litter addition in situ and nutrient factors input in laboratory on soil mineral N pools and N mineralization in the eastern Qinghai Tibet Plateau were explored. A significant decrease in soil MBN content, NH4+-N content, increase in soil NO3-N content and net N mineralization, and no change in DON contents were observed with litter input. Direct input of C in laboratory decreased mineral N pools, while mineral N contents increased when N was added. The results suggested that the soil N cycling was influenced by the addition of available C, and the C-limitation occurs in winter in the Eastern Qinghai Tibet Plateau. |
