Shuitu Baochi Xuebao, 2011 利用汾河水库1956-2004年入库径流和降雨量资料,在采用统计学方法探讨径流和降雨变异分析的基础上,建立双累积曲线模型,分离出了降水变化和水土保持措施分别引起的径流变化量,在定义贡献率的基础上,分析水土保持措施和气候变化对径流演变的贡献。结果表明,1956-2004年49年来汾河水库入库径流和降雨均呈减少的趋势,但径流减少趋势明显;以入库径流突变年份为界将研究时段分为2段(1956-1982年和1983-2004年);水土保持措施的实施致使径流减少24.8mm,贡献率为87.1 ...

Shuitu Baochi Xuebao, 2003 降雨是影响低丘红壤坡地土壤侵蚀和养分随径流迁移的一个关键因子.利用三角量 水堰自动测量径流量和自动雨量计观测数据,分析了鹰潭小流域的季节性降雨径流特征.小流域降雨主要发生在4～6月,总量达512.4 mm,占观测时段总雨量的70.1%,而旱季7～9月仅为218.9 mm.上游、下游围堰累积径流量随旱季、雨季的变化表明:小流域降雨-径流- 土壤水界面水分转化可分为土壤水补给阶段(4月14日～6月14日)、土壤水饱和阶段(6月15 日～7月28日)和土壤水消耗阶段(7月28日以后 ...
