鄱阳湖流域年降水量周期、趋势及响应特征分析
An analysis of period,tendency and response characteristics of annual precipitation in Poyang Lake basin
摘要
Abstract
Morlet wavelet analysis method and Mann-Kendall non-infiltration statistics are used to analyze the period,tendency and abrupt change characteristics of annual precipitation orders in the years of 1953-2010 at 16 meteorological stations in Poyang Lake basin and to make a contrast analysis of the period,tendency and abrupt change characteristics between annual precipitation and annual runoff,and annual runoff.Research results indicate that there exist 3 main periods, being 22 a,7 a and 4 a respectively in the annual precipitation orders in Poyang Lake basin.The overall annual precipitation in the years of 1953-2010 appeared to have no obvious growing tend-ency in Poyang Lake basin,and in 1992,there occurred to have obvious change with the confi-dence reaching 9 5%;the periodic variation and tendency abrupt change in the annual runoff in Poyang Lake Basin are in coincidence with the annual precipitation in temporal scale,time point, spatial distribution and obvious degrees,whereby that there exists an obvious response relation-ship between the annual precipitation and the annual runoff in the period,tendency and abrupt change in Poyang Lake basin.关键词
