| 摘 要： | 基于1997-2003年的气象水文资料,选择了黄土高原泾河流域上游,对半分布式生态水文模型SWIM进行了率定和验证,并以流域历史气象条件为基准,固定其它气候因素不变,针对单一气候因素变化(降水或温度)进行了情景模拟,分析、评价了降水和温度对流域径流量、蒸散量和土壤蓄水量各水文过程的影响。结果表明:流域降水量增加(减少),年径流、蒸散及蒸散分量、土壤蓄水量均增加(减少),且降水转化为各水量平衡分量的比例大小依次为径流量(蓝水)>蒸散量(绿水)>土壤蓄水量;流域温度升高,蒸散及其分量随之增加,但径流和土壤蓄水量则随之相应减少。研究结果对于变化环境下的干旱区流域水资源管理具有一定的意义。

| Abstract: | The 1997-2003 basic atmosphere and hydrology data were used and the medium-scale basin of Yellow River,the upstream of Jinghe basin was selected as the object and hydrological process simulation was carried out with semi-distributed eco-hydrological model and the SWIM model.Based on the history climate,the climate scenarios of single climate factor change,such as precipitation or temperature were set to simulate and analyze the hydrologic responses to the climate change.The result showed that runoff,evapotranspiration and its components,and soil water storage of the basin were affected greatly by climate change.Runoff,evapotranspiration and its components,and soil water storage increased with increasing of precipitation,and the propotions of water balance components transferred from precipitation was runoff > evapotranspiration > soil water storage.When temperature rose,evapotranspiration and its components increased,but runoff and soil water storage decreased.The research may be helpful to water resource management under the climate change in arid area. |
