| 摘 要： | 为研究云南昭通市地表水质污染程度,对其8个区县分别进行了布点采样,依据国家地表水环境质量标准,对这些地区的水质情况加以分析和评价。结果表明,本次研究的水样中总氮浓度超过V类标准的占56%,总磷浓度超过V类标准的占13.8%,昭通市地表水受到总氮（主要为硝态氮）污染非常严重,总磷污染则相对较轻。说明该市地表水受到严重污染。

| Abstract: | In order to study the extent of surface water pollution of Zhaotong in Yunnan province, eight counties of it are sampled. The water quality in these areas is analyzed and evaluated according to the national Environmental Quality Standards of Surface Water. The results show that the TN concentration of 56% of the samples is worse than the Grade V and the TP concentration of 13.8% of the samples is worse than the Grade V. The surface water in Zhaotong is seriously polluted by the total nitrogen （mainly as NO3 ）, the total phosphorus pollution is relatively light. It tells us that the surface water in Zhaotong Municipality is seriously polluted. |
