摘要： The annual emission of sulfur gases (H2S and COS) from different tidal flats in the Yellow River Delta, China were studied from February to December 2013 by using static chamber-gas chromatography technique. The result showed that the annual emissions of H2S and COS were featured with obvious seasonal variations. For the full year, the high tidal flats, middle tidal flats and low tidal flats were all the emission sources for H2S, and the range was on the order of 0.14-7.31 mu g.m(-2).h(-1), 0.22-6.38 mu g.m(-2).h(-1) and 0.23-8.80 mu g.m(-2).h(-1) respectively, and the means were 3.37 mu g.m(-2).h(-1), 1.98 mu g.m(-2).h(-1) and 3.29 mu g.m(-2).h(-1) respectively. For COS, the high tidal flats were also the emission sources, while the middle tidal flats and the low tidal flats were the sink, and the range was on the order of -1.16-2.52 mu g.m(-2).h(-1), -3.32-1.25 mu g-m(-2).h(-1) and -5.53-1.78 mu g.m(-2).h(-1) respectively, and with means of 0.68 mu g.m(-2).h(-1), -0.09p.g.m-2.h-1 and -0.17 mu g.m(-2).h(-1) respectively. The annual emissions of H2S and COS from the different tidal flats in the Yellow River Delta China were significantly affected by the annual seasonal variation, and the emissions of H2S and absorptions of COS from the different tidal flats were mainly concentrated in the growing season of plants (from May to October). In the different tidal flats areas, the annual emission amounts of H2S and COS were also different, among which H2S was manifested as low tidal flats > high tidal flats > middle tidal fiats, and COS as high tidal flats > low tidal flats > middle tidal flats.
