基于季节性 Kendall 检验法的 白石水库水质变化趋势

白石水库作为辽西地区重要的供水水库, 对其进行客观的水质评价将有助于水库水资源的保护, 为其科学管 理提供依据。以白石水库坝前水质为样本, 采用季节性 Kendall检验法对总氮、 氨氮、 溶解氧、 高锰酸盐指数等多项 水质指标进行趋势性理化分析。结果表明, 白石水库总氮严重超标, 且恶化趋势明显, 对白石水库的水质管理仍需 进一步加强。 The Baishi reservoir is an important water supply reservoir in the west of Liaoning Province, therefore an objective e 2 valuation of water quality contributes to the protection of water resource and provides the basis for scientific management of res2 ervoir. In this paper, the physical and chemical tendency analysis of the total nitrogen, ammonia nitrogen, dissolved oxygen and permanganate index was conducted based on water samples in the front dam of Baishi reservoir using the seasonal Kendall test method. The results showed that the total nitrogen in the Baishi reservoir exceeds the standard and has a deteriorative trend, so the management of water quality in the Baishi reservoir needs to be further strengthened. 公益性行业( 农业) 科研专项项目( 201303125)
