摘要
基于滦河流域三道河子站、承德站和滦县站1956～2009年的降水和径流资料，运用Mann-Kendall秩次相关检验等方法系统分析了滦河流域径流和降水的年际、代际、年内变化特征及变化趋势，并采用降水一径流双累积曲线法定量分析了降水和人类活动对径流变化的影响。结果表明，滦河流域径流年际变化剧烈，代际变化明显，径流年内分配极不均匀，主要集中在6～9月；滦河流域降水和径流的演变特征基本一致；不同时期降水和人类活动对径流的影响不同，人类活动是滦河流域径流变化的主要驱动因子。
According to the precipitation and runoff data of three hydrological stations （Sandaohezi, Chengde and Lu- anxian） in Luanhe River Basin during the period of 1956-2009, the Mann Kendall trend analysis and other analysis meth- ods are applied to analyze inter annual, inter-generation and annual variability and the trend of runoff and precipitation in the Luanhe River Basin. The double mass curve for annual rainfall stream flow method is applied to quantify the impact of precipitation and human activities on the runoff. The results show that both the inter-annual and inter-generation variability of runoff are drastic in the Luanhe River Basin; annual runoff of Luanhe River Basin is very uneven distributed and mainly contributed by those occurring from June to September; both runoff and precipitation of Luanhe River Basin have the same evolution characteristics; at different periods, the precipitation and human activities have different impacts on runoff; the change of runoff in Luanhe River Basin can mainly he attributed to human activities.
