黄浦江上游水源保护区非点源污染分析

黄浦江上游非点源污染已经成为影响其水质的重要因素．介绍了6类主要的非点源污染源，以CODcr，TN和TP为指标，用等标污染负荷法研究分析了2000年和2005年保护区内非点源污染的排放状况．结果表明：2000年畜禽粪尿、地表径流和生活污水的污染贡献率最大；2005年地表径流污染贡献率最大，生活污水的污染贡献率次之．

Analysis on non-point pollution source in the conservative zone of the upper reaches of Huangpu River

Non-Point pollution source in conservative zone of the upper reaches of Huang-Pu River has become an important factor influencing the water quality. This paper analyzed six types of primary non-point pollution sources, and took CODcr, TN and TP as proxies to study the pollution changes of the non-point pollution source with the equivalent standard pollution load method from year 2000 to 2005. The research results indicated that the excretion of animal husbandry, the surface runoff and living sewage contributed most to the pollution of the water in 2000, while the surface runoff becomes the main contributor to the pollution and the living sewage becomes less important in 2005.
