【摘要】水是生命之源,土是生存之本,水土是人类赖以生存和发展的基本条件,
是不可替代的基础资源。而土壤基本上是一种不可再生的自然资源,然而,由于
人们的过度开采,出现了水土流失现象水土流失能造成水、土、肥的损失,水冲
沙压良田,淤积山塘水库,提高河床,使生态环境恶化,给国民经济、工农业生
产、人民群众的生活带来的危害十分严重。对水土流失现象采取切实可行的防治
措施是当前急需解决的问题,做好水土保持的工作刻不容缓。

一、水土保持的必要性和重要性
为什么做好水土保持的工作刻不容缓,首先谈及到水土流失的危害。
(一)水库、河道淤积,水利工程遭破坏,易发生洪灾,损失严重。鲁山县
画眉沟水库, 于 1982 年建成,建成后仅灌溉一次,于当年七月一次暴雨,
万 m3 的库容淤积 万 m3,基本报废。黄山水库 1975 年一年就淤积 万
m3,相当于过去 20 年的总淤积量。
(二)水土流失使良田冲毁、土地沙化、地力减退。洛阳市嵩县与
