| 摘要: |
| 20世纪90年代以来,我国洪灾损失呈逐渐上升趋势,防洪形势十分严峻,除水文气象因素外,人类活动是重要影响因素.人类活动直接或间接地改变了影响洪水形成过程及其特征的某些自然环境因素,如陆面覆被、调蓄能力、地形、河流形态等.本文通过归纳国内外现有研究成果,从改变流域局部地区降雨径流关系,改变流域内河湖岸带滩地的蓄滞洪条件,改变洪水在河道中的输移条件等3个方面分析了典型人类活动对洪水特性的影响. |

| Abstract: |
| Since 1990,a gradually rising trend of flood damage has been apparent and the situation of flood defense is greatly severe.Besides hydrometeorological factors,human activity is an important factor causing much more flood damages.Human activities throughout watersheds directly or indirectly change some natural elements,such as land cover,available storage,land slope and river morphology,which influence flood-producing process and flood characteristics.By reviewing the existing literatures,this paper discusse... |
