摘要:
基于淮阴站1951~2015年的月降雨数据,应用不均匀系数、信息熵、集中度,集中期、重心等指数表征降雨年内分配不均匀性及集中程度特征,分别采用Mann-Kendall非参数检验方法和Pearson相关系数分析降雨年内分配特征年际变化趋势及各指标之间的相关性。结果表明:从时间上看,降雨年内分配不均匀性有降低,集中期有后移趋势,但幅度均较小,各指标均无突变趋势;年内分配不均匀系数、信息熵、集中度之间具有高度相关性,集中期与重心高度相关,不均匀系数、信息熵、集中度均与保证率存在显著相关。
Abstract:
Based on the monthly rainfall data of Huaiyin Station from 1951 to 2015, the uneven distribution coefficient, information entropy, concentration degree, concentration period, gravity center and other indexes were used to characterize the uneven distribution and concentration characteristics of annual rainfall, and Mann-Kendall nonparametric test method and Pearson correlation coefficient were used to analyze the annual distribution characteristics, inter-annual variation trend and correlation between various indicators.The results showed that the uneven distribution of rainfall during the year had decreased from the time point of view, and the concentration period had a tendency to move backward, but the amplitude was small, and there was no sudden change trend in each index.There was a high correlation between the annual distribution unevenness coefficient, information entropy and concentration degree, and the concentration period was related to the height of gravity center.The uneven distribution coefficient, information entropy, and the concentration degree were significantly related to the concentration degree.
