Abstract:[Objective] To explore the effects of reclamation mode on soil respiration in order to provide theoretical support for soil quality evaluation and reclamation mode selection in reclaimed region.[Methods] Using the analysis method of dynamic airtight chamber infrared CO2, the diurnal and seasonal variation of soil respiration rate and its related components in five permanent sample plots of opencast coal mine in Shanxi Province were studied.[Results] The soil respiration rate in each sample plot showed obvious seasonal variation, however, the law of diurnal variation of soil respiration rate was different. The width of diurnal variation of soil respiration rate in each sample plot was relatively gentle in May, September and October, and was bigger in June, July and August. The highest value of soil respiration appeared in July or August. Compared to the control, the root exclusion soil temperature and moisture was not significant difference, but the soil respiration rate was significantly declined by 19%~46%. The total and root exclusion soil respiration in relationship with soil temperature and moisture all can be described as a power function or exponential function, respectively.[Conclusion] Pure forest model of Robinia pseudoacacia is more advantageous to the improvement of the maturation and fertility of soil.
