中文摘要：
为探讨秸秆覆盖对土壤水分造成的影响,以希拉穆仁草原为研究对象,通过对地表覆盖不同量的秸杆,测定土壤水分、温度变化,试验表明：秸秆覆盖,有效抑制了土壤表面蒸发,不同处理土壤水分的差异性主要体现在表层（0 cm~30 cm）土壤,且随着深度的增加,土壤水分差异逐渐变小 秸秆覆盖的调温效应表现为高温时具有＂降温作用＂,低温具有＂保温效应＂,秸秆覆盖地表温度最高值出现时间滞后于对照,对地面5 cm处温度影响不大。
英文摘要：
The test was made in Xilamuren grassland in order to study the effect of straw mulching on soil moisture, soil moisture, temperature of different treatments were measured. Results show that： straw mulching inhibited soil evaporation effectively, there was significant difference on soil surface, the difference decreased with soil depth increasing; The adjusting temperature effect of straw mulching is decreasing temperature when temperature was high, increasing temperature when soil temperature was low, the temperature peak of soil surface temperature lagging behind CK, the change of 5cm temperature was not obvious.
