| 摘要: |
| 干旱与洪涝灾害已成为全球关心的重大问题.土地利用/覆被变化影响雨水的截留、下渗、蒸发等水文要素及其产汇流过程, 并进而影响流域出口断面的流量过程, 加大流域洪涝灾害发生的频率和强度.深入研究土地利用/覆被变化对洪涝灾害的影响, 对于社会经济可持续发展具重要意义.通过分析和总结已进行的有关流域土地利用/覆被变化的水文效应及洪水响应研究工作进展, 讨论了其研究内容、方法及现有工作的不足之处. |

| Abstract: |
| Drought and flood have been important issues around the world.Land use and land cover change influence hydrological factors such as interception, infiltration and evapotranspiration, the progress of water generation and concentration, then affect the discharge at the watershed outlet, and then influence the frequency and degree of flood.Taking this kind of study is of important significance for sustainable development of society and economy.The progress in the hydrological impact and flood response of watershed land use and land cover change is analyzed and summarized, and the study contents, methods and deficiencies are discussed. |
