On a rainy day,you will see many streams of muddy water running down the slopes(斜坡) of a hill.The water is muddy because it washes away soil from the hill slopes.Sometimes soil is blown away by strong winds.When the soil is carried away by water or wind,we say that the land is eroded(侵蚀).This is known as soil erosion.Plants cannot grow on eroded land.There is not enough soil on eroded land to give them the things they need.Planted need water and salt from the soil.We can do a number of things to stop soil erosion.This is called soil conservation.One way of soil conservation on flat,open ground is to grow small plants such as grasses.There roots hold the soil tightly together.Another way is to plant trees around an open field.Thus soil erosion by strong winds cannot take place.Rows of trees act as a very big wall.Soil erosion on slopes can be stopped by cutting “steps” called terraces(梯田).Water carrying soil cannot go straight down the slope now.It has to run down the terraces.

在一个下雨天,你会看到许多溪流浑水运行下跌的山坡山.水是泥泞的,因为它冲走泥土的山坡.有时土壤吹走的强风.当土壤中带走的水或风,我们说,土地侵蚀这就是所谓的土壤侵蚀.植物无法生长的侵蚀土地.没有足够的土壤侵蚀的土地给他们,他们需要的东西.种植需要水和盐的土壤.我们可以做一些事情,制止水土流失.这就是所谓的水土保持.方法之一水土保持的单位,公开地面增长小植物如草.有根举行土壤紧密合作.另一个方法是种树围绕一个开放的领域.因此,土壤侵蚀强风无法进行.一排排的树木作为一个非常大的墙.土壤侵蚀斜坡可以停止切割“步骤”进行所谓的梯田土壤水分不能直行山坡现在.它已经运行了梯田.这减缓了流动的水.大部分土壤在水中留下的梯田.还有其他的途径水土保持.
