摘要
根据陆浑水库2009—2015年水质逐月监测数据,应用综合营养状态指数对水库营养状态进行了分析,应用季节性Kendall检验法对溶解氧、高锰酸盐指数、硝酸盐氮、氨氮、总氮、总磷污染因子的变化趋势进行了分析研究,并通过建立陆浑水库的水环境安全评价指标体系,对水库的水环境安全状况进行了评价。结果表明:综合营养状态指数显示水库水体长期处于中营养状态,TN是制约水体富营养化的关键因素,磷是陆浑水库的限制性营养盐;2009—2015年陆浑水库水质状况相对较为稳定,并有改善趋势,基本处于较安全状态。
Based on the monthly water quality monitoring data of Luhun Reservoir from 2009 to 2015, the nutritional status and the changing trends of the main pollution indicators DO, CODMn, NO3-N, NH3-N, TN and TP were analyzed. The tendency of main pollution indicators was analyzed by using the seasonal Kendall test method. The comprehensive trophic state index shows that the reservoir water body is in a state of mild eutrophication for a long time. Nitrogen is the key factor to control the water quality level and eutrophication and phosphorus is the limiting factor of eutrophication. The water environment safety assessment results show that in the 2009-2015, the water quality of the reservoir is relatively stable and there is a tendency to improve, which is in a safer condition.
