摘要本文对1965 ~ 1975年11年的长江口硝态氮浓度和流量的周资料进行了统计分析。弗罗姆（多塞特）。结果显示，在11年的时间里，硝酸盐浓度每年增加0.11 mg NO3-N 1−1。1976年的硝酸盐浓度的预测模型，即使排放条件极端，平均预测的硝酸盐浓度为3.37 ± 0.136 mgNO 3-N1 - 1，非常接近观测到的平均硝酸盐浓度3.44 mgNO 3-N1 - 1。
SUMMARY. Statistical analysis has been carried out on 11 years (1965–75) weekly data of nitrate concentrations and discharge values from the R. Frome (Dorset). The results have shown a trend over the 11-year period with nitrate concentrations increasing by 0.11 mg NO3-N 1−1 per year. A predictive model for nitrate concentrations for 1976 was made and even though discharge conditions were extreme, the mean predicted nitrate concentration of 3.37 ± 0.136 mgNO3-N1−1 was very close to the observed mean nitrate concentration of 3.44mgN03-N1−1.
