| 摘 要： | 珠江西航道和流溪河在广州市区上游，为广州市主要水源区。由于感潮作用，受市区严重污染的水体因涨潮上溯而上游传输。严重影响上游水质。因此，弄清感潮作用对广州水源区水质的影响程度和范围，对水源保护与利用有重要意义。本研究从下游到上游，对水源区底泥中有机物特征进行了分析，结果表明：（１）从上游到上游，受感潮作用影响逐渐减小，污染程度逐渐减轻；（２）水源区有机物特征呈有规律变化。从靠近城市的下游到远离城市的

| Abstract: | Pearl River West Channel and Liuxi River,as main water source in Guangzhou,are in the upstream of urban city of Guangzhou,and their water quality is greatly deteriorated by the heavily polluted water going upstream from down stream due to tidal action Therefore,it is of great importance,particularly with regard to the protection and utilization of water source,to investigate to which degree and in which range the source water quality is influenced by tidal action We have carried out analysis of organic pollutants in surface sediments from down stream to upstream in the water source area,and the results reveals that from down stream to upstream,the water becomes less polluted,and the influence of tidal action on the water quality becomes less important.It is also shown that organics in samples from down stream to upstream exhibit a systematic change in origin,with organics in downstream near the urban area mainly coming from pollution by humanactivities,whereas organics in the upstream being predominantly from modern livings.Various geochemical parameters indicate a radical change of water quality between Shimen and Yagang,suggesting that water quality in the upstream of Yagang is not significantly influenced by tidal action |
