Abstract:: The typical maize sloping cropland was selected in the Loess Plateau of west He’nan to investigate the effect of different straw returning patterns on soil respiration using LI-8100A soil carbon fluxes measuring system. Three patterns of straw returning were set up: conventional tillage with no straw returning (CT), conventional tillage with straw incorporation into the soil (TSI) and conventional tillage with straw mulch on soil surface (TSM). The results indicated that the tendency of soil respiration in the studied period was similar under different straw returning patterns, and soil respiration varied from 0.22～1.23, 0.29～1.35, 0.26～0.91 μmol/(m²·s), respectively. The difference of soil respiration rates among three patterns was significant when the soil temperature and moisture was high, and soil respiration decreased in the order: TSI > CT > TSM; Soil respiration rates under different slope position were obviously different in all three treatments, decreasing in the order: lower position>middle position>upper position. The spatial difference of soil respiration was less under TSM treatment than other treatments, and the difference was significant as the soil temperature and moisture was higher. Soil temperature and moisture were significant different under different positions, decreasing in the order: lower position > middle position > upper position. There was significant linear relationship between soil respiration and soil temperature and moisture (p < 0.01) under all three treatments. Straw mulching decreased soil respiration in non-growing season, therefore, straw mulching was a rational method of straw returning from the point of reducing greenhouse gas emission.
