摘要
利用一个森林小流域的水文、气象资料,通过确定性水文模拟方法,探索了该地区的水文特性。通过分析,发现该流域水资源十分丰富,河川径流变化平缓,有利于综合开发利用。并得出了林冠能截留大量降水,森林土壤能贮蓄大量水分、调节径流成分并能削减洪峰、坦化出流过程的结论。
The paper focuses on the hydrological features of a small forested catchment by use of hydrologic model with determinacy. The data of hydrologic and meteorological is used for our study. After analysis, we find that the runoff yield of this region is very abundant and the distribution of runoff in a year is smooth, which is benefit for the water to be utilized. Also, we draw some conclusions as the following:the amount of intercepted water by forest canopy is very large; the soil of forested area is soft with many pores, so it can take a lot of wate and change the groups of water sources. At the same time, forest can reduce the flood magnitude and make hydrograph smoother. Therefore, conservation of forest is important for us all.
