| 摘 要： | 根据1954～1996年的降水、径流和泥沙等方面资料,对陕西省渭河流域的水沙动态变化进行统计分析,并对水沙变化的主要原因进行探讨,进而揭示水沙变化对环境因素的响应关系。结果表明,渭河流域水沙输送主要集中于降水量较大的汛期,年内分布相对集中;年际变化较大,从20世纪50年代到90年代总体均呈下降趋势;流域径流量、输沙量与环境要素之间存在密切的响应关系。

| Abstract: | According to the data of rainfall,runoff and sediment between 1956 and 1996,the variation of runoff and sediment in the Weihe watershed in Shaanxi Province was analyzed.And their main reasons were explored to further reveal response relationship between environment factors and variation of runoff and sediment.The runoff and sediment transport mainly occurred in concentrate in high-water season with high precipitation.In others words,their distribution were relatively concentrated.On the whole,the runoff and sediment transport declined between 1950s and 1990s and showed large inter-annual variations.In addition,the runoff,sediment and environment factors are closely related to each other. |
