| 摘 要： | 利用渭河干流林家村、咸阳和华县3个水文站1960年以来的径流资料,应用Kendall秩相关系数、R/S分析、降水-径流双累积曲线法等多种数值模型方法,计算分析了渭河径流的年内分配特征、年际变化特征、径流变化趋势、降水变化和人类活动对径流变化的影响。结果表明：①渭河径流量年内主要集中于5月-10月份,占年径流总量的75%左右;年际变化剧烈,1960年-1970年基本处于丰水期阶段,1994年后基本处于枯水期阶段,其余年份呈丰枯波动;②径流变化趋势现在处于极显著的递减状态（p〈0.001）,递减率处于-17.752（m3/s）/10a至-37.654（m3/s）/10a之间;未来的一段时间内将保持同一势态;③受人类活动和气候变化的影响,渭河径流发生了由多到少的突变;④渭河径流量减少的主要原因是人类活动,降水变化为次要原因

| Abstract: | Responses of river water resources to both human activities and climate change have gained increasing attentions in water research over the past decades, and is the key issue for river hydrological processes and sustainable use of regional water resources. Exploring evolution of water resources in the Weihe River under the influence of both human activities and global climate change will provide an important theoretical reference in understanding the hydrological characteristics of the Weihe River and the s... |
