| Abstract: | Taking Wuchengxiyu and Yangchengdianmao regions as examples,the paper investigates the temporal and spatial changes of extreme water levels in the river networks of Taihu Lake basin.The improved MK test and homogeneity test are used to detect trend and change points in the series of maximum and minimum water levels,and Kriging and semivariogram methods are adopted to analyze the spatial characteristics of water level changes.Furthermore,the relationship among extreme water levels,precipitation and human act... |
