| 摘 要： | 对黄土高原沟壑区不同种植年限果园土壤深层水分变化进行了研究。结果表明,受降水影响0~2m土层水分变化较大,且0~40 cm4、0~80 cm、80~200 cm三个土层土壤含水量之间的差异达到极显著水平;2 m以下由于没有水分的补给,土壤水分含量趋于稳定,出现了干燥现象。随着种植年限的增加,深层土壤的干燥化现象有增加趋势。 |

| Abstract: | Change of soil moisture in deep layer was studied in different planting-life in gully region of loess plateau.The results showed that,affected by precipitation,the soil moisture had great change in 0~2 m soil layer,and there was a significant difference among 0~40 cm,40~80 cm and 80~200 cm.Without water supply,soil moisture tended to be stable under 2 m soil layer which appeared desiccation.With the planting-life increasing,desiccation of deep soil layer tended to increase. |
| Keywords: | Loess plateau Orchard Moisture changes |
