| 摘 要： | 选择城市降水径流，采用实地降水径流的样品、室内化学分析相结合的方法，研究了上海市区降水径流中营养元素P的负荷及其地区分布特征。研究结果表明，城市降水径流中P具有较高的含量水平，其DOP、DIP和TP的均值含量分别为0．136、0．177和0．313mg/L。从城市降水径流中P负荷的空间分布来看、除农业区P含量较低外，其他功能区P含量普遍较高，其中居住区TP含量最高，达0．487mg/L。此外，新老居住区P含量也存在明显差异，前者远小于后者。

| Abstract: | Through urban precipitation-runoff sampling and chemical analysis.this article presented precipitation-runoff nutrient phosphorus loading and regional distribution in Shanghai proper. The results showed that in precipitation-runoff where contained higher nutrient phosphorus, mean DOP, DIP and TP concentrations were 0.136, 0.177 and 0.313mg/L respectively. Based on spatial distribution of urban precipitation-runoff nutrient loading, it was found that phosphorus concentration was generally enhanced with the exception of agricultural areas, while residential areas showed highest phosphorus concentration of 0.487mg/L. Meanwhile, phosphorus concentration also showed obvious difference between new and old residential areas, and the former was far lower than the latter. |
