摘要
通过对毛乌素沙地不同类型地农田防护林防护效益及经济效益的调查和定位观测，结果表明：毛乌素沙地农田防护林具有降低风速、调节改善气温、土温，提高空气湿度，减少水面蒸发的功能，农田防护林带作用下，农作物增产，并能够提供一定数量的木材。
The investigation and location observation on the economic and shelter-protective benefits from the different- typed farmland -protective forests shows that in the Maowusu sandy area shelter-forests are capable of reducing wind speed and evaporation,regulating local air and soil temperatures. Meanwhile,the shelter -forest can being higher agricultural preduction,as well as plenty of timbers.
