The H2S and COS emission fluxes from Suaeda salsa marsh in the Yellow River estuary were measured using the static chamber and Chromatogram method during the growth season (May to October), the results showed that the seasonal and diurnal variations of H2S and COS emission fluxes were obvious, and Suaeda salsa marsh in the Yellow River estuary was the sources for both H2S and COS during the growth time, and the mean H2S and COS emission fluxes from Suaeda salsa marsh were 4.97 microg x (m2 x h)(-1) and 0.92 microg x (m2 x h)(-1), respectively. Different environmental factors had different effects on the emission fluxes of H2S and COS from Suaeda salsa marsh, in which the SO4(2-) content and water content in the soil were the main factors that affected the H2S and COS emission fluxes, respectively. Sulfur gases emissions from Suaeda salsa marsh may be affected by many factors, such as plant, tide status and so on, so that should be further studied.
在生长季节(5月至10月),采用静态箱-色谱法对黄河口盐地碱蓬湿地的H₂S和COS排放通量进行了测定,结果表明,H₂S和COS排放通量的季节和日变化明显,黄河口盐地碱蓬湿地在生长期间是H₂S和COS的排放源,盐地碱蓬湿地H₂S和COS的平均排放通量分别为4.97μg·(m²·h)⁻¹和0.92μg·(m²·h)⁻¹。不同环境因子对盐地碱蓬湿地H₂S和COS排放通量的影响不同,其中土壤中SO₄²⁻含量和含水量分别是影响H₂S和COS排放通量的主要因素。盐地碱蓬湿地硫气体排放可能受植物、潮汐状况等多种因素影响,有待进一步研究。
