本文以某水文站50年的年平均和季节平均水温资料为例，讨论了用非参数Mann-Kendalltest方法对水温时间序列趋势和突变进行检验的适用性。通过对实际数据的分析计算和对相关主要因素测试结果的对比分析，表明mann - kendall检验法能较好地识别水温序列的长序列变化趋势和突变点。
By taking the data of theannual and seasonal average water temperatures within a period of 50 years from a hydrological station as the study cases,the applicability of the test on the trend and sudden change of the water temperature time series made by the method of the non-parametric Mann-Kendalltest is discussed herein. Through the analysis and calculation made on the actual data and the comparative analysis made on the testing result of the relevant main factors,it is indicated that the method of Mann-Kendalltest can better identify the long-series changing trend and sudden changing point of the water temperature series.
