近50a来塔里木河干流年径流量变化趋势及预测/Change trend and prediction of annual runoff in mainstream area of the Tarim River in recent 50 years[J]

, 2011
根据塔里木河干流1957-2008年的年径流量监测数据,利用Mann-Kendall非参数技术检验和R/S法,对干流年径流量时间序列变化趋势进行分析,并在此基础上采用滑动t检验法和Mann-Kendall法对其突变点进行检验,最后运用方差分析外推法和叠加趋势预测模型对干流水文周期和未来径流量变化进行分析和预测.结果显示:近50 a来,塔里木河干流的年径流量呈现显著递减的趋势,愈往下游线性下降趋势愈显著,随着时间推移,未来有继续下降的趋势,且下降的趋势会更加显著;径流突变分析表明,阿拉尔、新渠满 ...

1957年至2005年塔里木河干流径流变化趋势分析

, 2010
根据塔里木河干流1957年-2005年的年径流量监测数据,利用Mann-Kendall非参数检验技术和R/S法,对干流年径流量时间序列变化趋势进行分析,并在此基础上采用滑动t检验法和Mann-Kendall法对其突变点进行检验。结果显示:①近50年来,塔里木河干流的年径流量呈现显著递减的趋势,愈往下游线性下降趋势愈显著,随着时间推移,未来有继续下降的趋势,且下降的趋势会更加显著;塔里木河干流径流年内分配受人类活动影响强烈,主要集中在夏季(6月-8月),占全年径流量的50%以上;②突变点分析表明,阿拉尔 ...

策勒河出山径流特征及其趋势

, 2009
根据策勒河近50年水文及气象资料,利用经验频率、Mann-Kendall非参数检验和非线性回归分析等方法,分析策勒河径流量的变化特征、变化趋势及其对气候的响应。结果表明:策勒河径流年内分配不均,夏、秋季偏丰,5～9月径流量占全年88.70%;冬、春季偏枯,10月到次年4月径流量占全年11.30%,策勒河变差系数为0.21,径流最大值与最小值之比为2.53,河流年际变化相对稳定;Mann-Kendall检验得出近十年出山径流量有减少的趋势;月平均流量与月平均降水量 ...
