| Abstract: | Soil respiration is of great importance in mass circulation and energy flow through ecosystems.It is also an index for many functional processes of ecosystems.In this paper,methods of measuring soil respiration were compared.Rates of soil respiration and quantities of annual CO\-2 release from different grasslands were summarized.And factors affecting soil respiration were discussed.The paper suggested emphases of further study in this field. |

| Keywords: | soil respiration grassland CO2 enrichment |
