| 摘 要： | 为揭示天津市水源地于桥水库气候变化对水质的潜在影响,采用广义可加模型(generalized additive model,GAM)对2000—2011年的气象数据及水质数据进行非参数回归分析,研究降雨量、最大风速和太阳辐射与悬浮物(SS)、总磷(TP)之间的相关关系。结果表明,3种气象要素均对SS浓度具有一定影响,最大风速与SS在春季表现出显著的正相关关系,太阳辐射与SS在全年样本中同样表现为良好的正相关;由于SS的吸附性及再悬浮作用,TP与SS间也表现出显著的正相关关系。

| Abstract: | In order to reveal the potential impacts of climate change on water quality in Yuqiao Reservoir, Tianjin water source area, the generalized additive model(GAM)was used to analyze the non-parametric regression of meteorological data and water quality data from 2000 to 2011. The correlation between rainfall, maximum wind speed, solar radiation, suspended solids(SS)and total phosphorus(TP)were studied. The results show that the three meteorological factors have certain effects on SS concentration. The maximum wind speed has a significant positive correlation with SS in spring, and the solar radiation and SS also have a good positive correlation in annual samples. Due to the adsorption and resuspension effect of SS, TP and SS also show a significant positive correlation. |
