摘　　要：通过对1995—2004年上海市嘉定区内各个不同类型的污染控制断面BOD5、CODcr，监测结果的统计，得出各年的B／C值及其10年的均值。这些数据一定程度上反映了嘉定区整体水系的有机污染状况。进一步研究发现．在B／C值稳定的地表水中，BOD5与CODcr有良好的相关性，此相关性对以后区域水系中断面地表水CODcr，BOD5的数据质保提供了借鉴。BOD5 and CODcr levels at various kinds of pollution-control sections on the rivers in Jiading district of Shanghai from 1995 to 2004 were collected, and the annual B/C ratios were figured out as well as the tenyear average. To some extent, the statistics have reflected the status of organic pollution in the water system in Jiading district. Through further study, a good correlation has been found between BOD5 and CODcr in the surface water where the B/C was stable. This correlation can provide some references for the quality assurance （QA） and quality control （QC） in the future BOD5 and CODcr monitoring of the surface water.
