Abstract

Abstract: Using the static chamber-GC technique, greenhouse gas (CO₂, CH₄, N₂O) fluxes of sand dunes and meadow wetlands were measured in a typical sand dune-meadow cascade ecological zone of Horqin. The dynamics of the greenhouse gas fluxes and driving factors were analyzed. The results showed that soil CH₄ flux underwent absorption during the growing season, with average CH₄ fluxes of semi-mobile dunes and meadow wetlands were -52.7 μg·m^-2·h^-1 and -34.7 μg·m^-2·h^-1, respectively, ranging from -176.1 to 49.8 μg·m^-2·h^-1. The peak of CH₄ absorption in the growing season occurred at August 22nd, 2017. In August and September, the months with heavy rainfall, the CH₄ flux in meadow wetlands showed continuous emission, being significantly different from that in semi-mobile dunes. The peak of N₂O flux during the growing season was at July 21st. The monthly average N₂O flux in semi-mobile dunes was following the order of July > August > September > June > May. Soil temperature and moisture were the key factors affecting CO₂ and CH₄ fluxes, whereas the N₂O flux was mainly affected by soil temperature. The soil temperature sensitivity (Q₁₀) showed the sequence of semi-mobile dune (1.009) < meadow wetland (1.474). The water stress rendered the greenhouse gas fluxes in semi-mobile dunes being less sensitive to soil temperature change than that in meadow wetlands.
