随着生产的发展和人口的增长,水资源的消耗量急剧增加;一些国家和地区供水问题日益紧张;有的地方严重缺水。因此,河川流量的消长变化越来越引起世界各国的重视。许多国家的学者对此进行了大量研究,揭示出森林是影响河川流量的一个重要因素。而森林对河川年流量的影响则是森林与水的关系中的一个重要方面。 With the development of production and population growth, the consumption of water resources has risen sharply; the water supply problems in some countries and regions have become increasingly tense; and in some places, there has been a serious shortage of water. Therefore, the fluctuation of river flow changes more and more aroused the attention of all countries in the world. Scholars in many countries have done a lot of research on this, revealing that forests are an important factor influencing river flow. The impact of forests on river flow is an important aspect of the relationship between forests and water.
