英文摘要	Diurnal variation characteristics in the respiration of four reconstructed soil masses in a barren gravel land were monitored using soil carbon flux measurement system. The results showed that (1) the variation had a single-peak curve, with the lowest value recorded at 6:00 or 20:00, and the highest value at 10:00, 12:00, or 14:00. The soil respiration values of the four reconstructed soil masses reached the maximum and minimum in August and January, respectively. (2) The variation can be explained by a single factor of soil temperature (i.e., index model), soil volumetric water content (i.e., quadratic model), or both factors (i.e., power-index model). However, the explanatory power was different, i.e., generally higher than 50.0% for the two-factor model, and the interpretation ability of temperature was significantly higher than that of water for the single-factor model. (3) The three-model fitting of the hydrothermal factors and reconstructed soil mass, with the added meteorite, showed that these factors had the lowest ability to explain the diurnal variations in soil respiration. In contrast, the quadratic curve model of the soil volume water content and reconstructed soil mass, with the added shale, had the highest ability to interpret the diurnal variation in soil respiration.
