| 根据调查资料和河流断面取样点的月度监测数据，研究了潇河支流白马河段水质的时空变化特征，并对水质富营养化程度进行了评价。结果表明，白马河水质较差，属于GB3838-2002《地表水环境质量标准》劣Ⅴ类水质，河流附近乡镇未经处理的生活污水以及造纸废水的排放是造成白马河水质污染的主要原因。从空间尺度上看，化学耗氧量(COD)、氨氮(NH3-N)、总磷(TP)含量分别沿河流从上游的171.926 mg/L、3.248 mg/L、0.616 mg/L降低到下游的34.920 mg/L、0.560 mg/L、0.208 mg/L，表明白马河水体具有一定的自净能力，但自净能力较差；在时间变化特征上，COD、NH3-N、总氮(TN)含量10－12月逐渐降低至171.926 mg/L、3.248 mg/L、4.233 mg/L，但COD在1月突然升高至308.772 mg/L，之后又逐渐降低，NH3-N从1月开始快速回升，至2月达到最高值16.576 mg/L，TN在4月达到最高值18.342 mg/L，之后急速降低；总磷含量在0.868～0.397 mg/L之间波动，无明显变化规律。 |

| In this study , the spatial and temporal variations of water quality of the Baima River, a tributary of the Xiaohe River, were analyzed, and the trophic state of water quality was also evaluated according to the investigation data and monthly monitoring data at the sampling points. The results suggested that the water quality of the Baima River was inferior to Grade V in light of the Surface Water Environment Quality Standard (GB3838-2002).The major sources of water pollution were discharge of untreated sewage and wastewater from a paper-making factory near the river. The content of chemical oxygen demand(COD), nitrite ammonium (NH3-N) and total phosphate (TP) showed a significant spatial variations, with the highest values of 171.926 mg/L, 3.248 mg/L, 0.616 mg/L in the upstream and down to 34.920 mg/L, 0.560 mg/L, 0.208mg/L in the downstream ,respectively, indicating that the water of the Baima River had the self-purification ability, but this ability is relatively limited. COD, NH3-N and total nitrogen (TN) also presented a monthly variation during the monitoring period. From October to December, COD , NH3-N and TN gradually decreased to the lowest value of 171.926 mg/L、3.248 mg/ and 4.233 mg/L ,respectively, then increased to the peak value of COD (308.772 mg/L ) in January and NH3-N (16.576 mg/L) in February and TN (18.342 mg/L) in April, and then COD , NH3-N and TN began to decrease quickly.The contents of TP fluctuated between 0.868-0.397 mg/L, without obvious change. |
