浙江来水与黄浦江上游支流总磷和氨氮变化规律分析

The Water from Zhejiang into Upstream Tributary of the Huangpu River Total Phosphorus,Ammonia Nitrogen Variation Law of Analysis

利用浙江来水汇入黄浦江上游支流的3个断面2000—2009年10年的总磷和氨氮监测资料,分别对同一断面在丰水期、平水湖、枯水期的浓度以及同一水期不同断面的浓度,利用SPSS统计分析软件,对总磷、氨氮的浓度变化规律进行分析,在此基础上采用Spearman秩相关分析方法进行相应的趋势分析,揭示出总磷、氨氮在不同水期、不同断面的变化规律以及浓度变化趋势。

This paper analyzes the variation laws of the concentration of total phosphorus and ammonia- nitrogen both on the same section as the different seasons of Abundant, usual and dry water levels and also on the different sections in the same water season by the usage of SPSS statistical analysis software according to the monitoring data of ten years （2000--2009） of total phosphorus and ammonia on the three sections imported from the Zhejiang upstream to the Huangpu River. On the basis of the above analysis, the corresponding trend analysis used the method of Spearman rank correlation analysis reveals the variation laws and the trend of concentration of total phosphorus and ammonia at the different water seasons and sections.
