摘要
利用静态箱／气相色谱法，观测了生长季（5—10月）黄河三角洲翅碱篷湿地H2S和COS的释放动态．结果表明，H2S、COS的排放通量具有明显的季节和日变化规律，在生长季，黄河三角洲翅碱篷湿地是H：S和COS的释放源，其中H2S的平均释放通量为4．97μg·（m3·h）-1，COS的平均释放通量为0．92μg·（m2·h）-1．在探讨的环境因子中，不同环境因子对翅碱篷湿地H2S和COS释放通量的影响不同，其中土壤S02/4-含量是影响H2S释放通量的主要因素，土壤含水量是影响COS释放通量的主要因素．含硫气体的排放可能还受到其它因素如植物、潮汐状况等多种因素的影响．
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 μg · （m2·h） -1 and 0. 92μg · （m2 ·h）-1, respectively. Different environmental factors had different effects on the emission fluxes of H2S and COS from Suaeda salsa marsh, in which the SOl- 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.
