摘要: 本文从水量平衡观点对林带、牧草地和裸露地的水量平衡各分量的变化规律进行了探讨。林带、牧草地和裸露地水量平衡各分量的分配比例分别为:降水均为100%;蒸发散96.4%、95.7%和89.5%;坡地径流3.6%、4.3%和10.5%。由于林带有林冠和林地两个作用面组成,分别对它们的水量平衡各分量的组成及其变化规律作了分析。还论述了林带对河川径流的影响。

Abstract: Variational regularity of various components of water balance in forestbelt, grassland and bareland is explored from view point of water balance. The distribution proportions of various components of water balance in forestbelt, grassland and bareland are respectively: 1) All precipitation100%; 2) evapotranspiration96.4%, 95.7% and 89.5%; 3) slope runoff 3.6%, 4.3% and 10.5%. Since the forestbelt consists of canopy and forestland, their compositions of various components of water balance and variational regularity were analysed. The effect of forestbelt on river runoff is discussed.
