【摘要】 基于淮河中上游1960～2016年日降水、日平均气温数据和1969～2013年洪泽湖实测出入湖流量数据,采用线性趋势分析、5年滑动平均、Mann-Kendall检验、Pettitt突变检验、Morlet小波分析及R/S分析等多种方法,进行水文气象要素时间序列的趋势分析、突变检验和周期分析,并预测未来变化趋势。更多还原

【Abstract】 Based on the daily precipitation and daily average temperature data from 1960 to 2016 in the upper and middle reaches of the Huaihe River, and the measured water flow data of Hongze Lake from 1969 to 2013, a variety of methods such as linear trend analysis, 5-year moving average, Mann-Kendall test,Pettitt mutation test, Morlet wavelet Various methods and R/S analysis were used to perform trend analysis,mutation test and cycle analysis of hydrometeorological elements time series, and predict future trends.更多还原
