摘要
在分析云龙库区来水河流水质数据的基础上,深入分析入库河流水质和云龙水库水质、污染来源、贡献率、营养盐变化趋势、分布特征、污染特征,研究结果表明库区河流水质部分指标超其水功能要求,水库水质总体为Ⅱ类,部分超Ⅱ类水功能保护目标,水体为中度营养状况,部分水域出现蓝藻暴发。在此基础上提出防治对策。
The water qualities of Yunlong reservoir and the rivers flowing into the reservoir were analyzed. On the basis of the analysis, the pollution sources, the contribution rates, the trends of nutrients, the distribution and pol-lution characteristics were analyzed as well. The results indicated that the water quality of the reservoir could meet the second class of national standard in general. However, several water quality indices could not meet the water quality standard. The water body was mesotropher. Algae occurred in parts of the reservoir. Countermeasures were put forward.
