晋西黄土高原地区,特别是黄土丘陵沟壑区,地形支离破碎,沟壑纵横多为童山秃岭,加之暴雨集中,强度大,水土流失最为严重,每平方公里年侵蚀量平均在一万吨左右,致使土地日益贫瘠,自然条件极差。恢复森林被复是改变这一地区恶劣的自然条件,根治水土流失,减免生态灾难的根本途径。但如何经济、有效地开发利用当地水土资源,为大面积森林植被的恢复创造有
In the western Shanxi Loess Plateau, especially in the loess hilly and gully areas, the terrain is fragmented and the ravines are mostly bald tonglangling. In addition, heavy rains concentrate, intensity is high, soil erosion is most serious, and the annual erosion amount is about 10,000 tons per square kilometer, resulting in The land is increasingly barren and has very poor natural conditions. Restoration of the forest complex is the fundamental way to change the harsh natural conditions in this area, and to eradicate soil erosion and reduce or eliminate ecological disasters. However, how to develop and utilize the local water and soil resources economically and effectively, and create a large-scale restoration of forest vegetation
