| 摘要: |
| 底泥耗氧量占据河流溶解氧消耗的一大部分，几十年来国内外学者对不同类型河流的底泥耗氧量展开大量试验研究.对国内外非悬浮底泥试验和悬浮底泥试验的主要试验方法进行总结，并阐述了不同方法各自的优缺点及相应的适用范围.底泥中生物系统的作用、水温、底泥的有机质含量影响河流底泥中生物和化学氧化过程，从而影响底泥耗氧量.另外，底泥的组成情况、上覆水体的流动速度和水深，以及上覆水体的水质等因素与底泥耗氧量也有一定相关性.最后，在总结前人研究工作的基础上，提出了对代表性的水域底泥耗氧量的试验方法、底泥耗氧量主导影响因素以及河流中的底泥耗氧量作进一步研究. |

| Abstract: |
| Sediment oxygen demand (SOD) accounts for significant oxygen sink in rivers. A few studies of different streams around the world have been conducted. This review introduces the major experiment methods to measure the sediment oxygen demand in non-suspended sediments and suspended sediments. It also discusses the advantages and disadvantages of different methods and their applications. Microbial process， temperature and content of organic matter affect both biological and chemical oxidation, and consequently they influence the SOD. In addition， the particle size of sediment， flow velocity， water depth and water quality are related to SOD. Finally， on the basis of the previous works， further studies on experiment methods of typical waters， dominant influence factors and sediment oxygen demand in rivers are proposed in this study. |
