| 摘 要： | 我们使用流域内(黄河中游河龙区清水河流域水文站断面以上425km~2)不同时期航片,判读出森林的动态变化。然后依据27年的水文资料,分析森林的动态变化对径流、泥沙的影响。研究表明:由于森林面积的增加以及土壤下渗和蒸发散的增加,年径流量、枯水期流量、洪峰流量以及悬移质输沙量都不同程度地减少。 |
| 关 键 词： | 航片 森林覆盖率 年径流量 枯水 洪水 悬移质输沙量 |

| Abstract: | The Clear River watershed is located in the middle reaches of the Yellow River. Here, the upper hydrology station has an area of 425 km~2. Ariel photographs taken during various periods show a clearly defined and recognizable forest development pattern. Additional hydrology data, for the past 27 years, shows the affect on runoff and sedimentation by the development of the forest. Research and analysis shows that as the forest grows, it affects a number of parameters: annual runoff, runoff during the dry season, annual flood and annual sediment discharge. These changes result from an increase in the infiltration rate and the evapotranspiration rate. |
