运用多测站校正检验机制率定方法,应用MIKESHE模型量化评价土地利用与降水变化对流域水文的影响。结果表明,尽管MIKESHE模型在流域上游大阁站的模拟性能稍逊于下会站和戴营站,3个测站校正和验证阶段的Nash-sutchliffe系数值分别为0.56和... 运用多测站校正检验机制率定方法,应用MIKESHE模型量化评价土地利用与降水变化对流域水文的影响。结果表明,尽管MIKESHE模型在流域上游大阁站的模拟性能稍逊于下会站和戴营站,3个测站校正和验证阶段的Nash-sutchliffe系数值分别为0.56和0.49、0.65和0.69、0.57和0.68,但模型对于各测站平均径流的模拟效果较好,说明该模型在潮河流域等华北土石山区具有一定的适用性和应用潜力。与基准期(1963—1979年)相比,1980—1989年潮河流域年径流量减少约22 mm,土地利用与降水变化对流域水文变化的贡献相当,两者分别占总径流变化的59%和41%;1990—1999年年径流量较基准期基本没有变化,这主要是由于降水变化与土地利用变化对流域水文的影响作用相反;2000—2008年,流域年径流量较基准期减少35 mm,降水变化对径流减少的影响作用占80%,土地利用变化则占20%。 展开更多

This article outlines the major scientific objectives of the SHui project that seeks to optimize soil and water use in agricultural systems in the EU and China,by considering major current scientific challenges in this area.SHui(for Soil Hydrology research platform underpinning innovation to manage water scarcity in European and Chinese cropping systems)is large cooperative project that aims to provide significant advances through transdisciplinary research at multiple scales(plot,field,catchment and region).This paper explains our research platform of long-term experiments established at plot scale,approaches taken to integrate crop and hydrological models at field scale;coupled crop models and satellite-based observations at regional scales;decision support systems for specific farming situations;and the integration of these technologies to provide policy recommendations through socio-economic analysis of the impact of soil and water saving technologies.It also outlines the training of stake-holders to develop a basic common curriculum despite the subject being distributed across different disciplines and professions.As such,this article provides a review of major challenges for improving soil and water use in EU and China as well as information about the potential to access information made available by SHui,and to allow others to engage with the project. 展开更多
