摘　　要：通过对扬州市古运河底质样品的实验研究,获得底质耗氧速率与流速的关系,底质静态耗氧速率、底质耗氧物质释放率计算模型,以及模拟船舶行驶影响底质耗氧的实验结果。说明现存于河底的淤积物的耗氧是造成古运河水质严重恶化的重要原因之一。从而提出,要彻底改善古运河水质,除了采取一系列治理污染源的措施外,还必须重视底泥问题,疏浚河道,清除这一次生污染源,以适应供水、航运、防洪和环境保护的需要。By experimental study of Yangzhou ancient canal's silt samples,this paper ob- tains the following results:the relationship between silt oxygen consumption rate and flow ve- locity;the compute model of silt oxygen consumption rate in calm water and silt oxygen con- sumed material releasing rate;the simulation result of the running ship's influence on silt oxy- gen consumption. These results show that silt oxygen consumption is the main reason of the poor quality of ancient canal's water.
