秦岭横贯我国中部,是中分南北的自然分界线和长江、黄河两大流域的分水岭;森林资源和水利资源丰富,又是庇护我省关中八百里秦川和陕南汉中、月河、商丹盆地农业生产的天然屏障。但是,由于多种原因,秦岭林区的森林植被不断遭到破坏。近几年来,水文、气象特征发生了不利的变化,特别是1981年秦岭西部地区发生特大暴雨洪灾之后,人们愈来愈关心秦岭森林,对护林保水问题更为重视。根据我们多年对秦岭森林、水文方面的调查,就秦岭森林的蓄水保土作用谈几点意见。
Qinling Mountains runs through central China, which is the natural dividing line between north and south and the watershed between the two major drainage areas of the Yangtze River and the Yellow River. The forest resources and water conservancy resources are abundant. It also protects 800 miles of Qinchuan in Guanzhong and Hanzhong, Natural barriers to agricultural production in the Dan basin. However, due to various reasons, the forest vegetation in Qinling Mountains has been continuously destroyed. In recent years, hydrological and meteorological features have undergone unfavorable changes. Especially after the extraordinary torrential rains and floods in the western part of Qinling in 1981, people are more concerned about the Qinling forests and pay more attention to the protection of forests. According to our many years of Qinling forests, hydrological surveys, on the role of the Qinling Mountains water storage soil talk about some ideas.
