摘要: 山东省水土流失面积44300平方公里,占全省山地、丘陵的79.3%。以沂蒙山区最为严重,蒙阴县具有代表性,平均每亩耕地每年流失土壤2.09米3,使土层减少3毫米。对自然植被的破坏是造成水土流失的主要原因,其他原因如开荒、滥牧、栽培植被的不合理布局和种植等。恢复森林是水土保持的根本措施,同时必须禁止不合理的开荒、滥牧和耕作方式,以及搞好农田基本建设,才能有效的控制水土流失,从而发展生产和提高群众的生活。

Abstract: The area of soil and water erosion in Shandong Province amounts to 44300km2, 79.3% of the total mountainous and hill regions in Shandong. Yi-Meng mountainous area is the most serious one in Shandong Province. Mengyin County is a typical case, the average amount of erosion soil in farmland is 2.09m3/mu/yr., resulting in a reduction of 3mm from soil layer.Destruction of the natural vegetation cover is the main cause of soil and water erosion. Other causes include reclamation, uncontrolled grazing, unreasonable overall arrangement of cultivated vegetation and unreasonable farming.Recovery of the forest is a fundamental measure for soil and water conservation. Besides, effectively controlling the soil and water erosion, prohibiting unreasonable reclamation, uncontrolled grazing and farming system, and carrying on effectively capital construction work on the farm are also necessary measures. Thus we can promote production and raise the living standard of the masses.
