摘要

为掌握黄土高原切沟对其上方集水区内土壤水分的影响

选取晋西黄土区典型切沟上方的集水区为研究对象

采用土钻法定期测量0—10 m土层的土壤水分

探讨集水区内不同地貌部位的土壤水分状况。结果表明:(1)集水区内土壤水分状况受距离切沟远近和地貌部位的共同影响。(2)集水区内距离切沟1 m处的蓄水量显著低于距离切沟3

6 m处的蓄水量(P＜0.05)

集水区内洼地的蓄水量大于坡面。(3)集水区内6个采样点浅层含水量随时间变化剧烈

深层含水量随时间变化小。(4)切沟对其上方集水区内土壤水分的水平影响距离为1~3 m

距切沟1 m处

影响深度最深可达7 m

距切沟3 m处

影响深度为2 m。在未来开展切沟治理中

建议在距离切沟1 m范围内密植低耗水的耐旱灌木或草本

利用密植的植物增加地面糙率

降低水流流速

并利用植物根系网络土体

增加抗冲性

从而起到防治切沟溯源侵蚀。

Abstract

We selected catchment area above typical gully in the loess region of western Shanxi Province to study effects of gully on soil water content in the catchment area above in the Loess Plateau. The soil water content in a profile of 10 m was measured by soil core method and we discussed the soil moisture status of different landforms in the catchment area. The results showed that:(1) The soil moisture status in the catchment area was affected by the distance from the gully and the landform. (2) Soil water storage at 1 m from the head of the gully was significantly lower than that at 3 and 6 m. Soil water storage was higher in the depression than in the slope. (3)The shallow soil water content of 6 sampling points changed sharply with time

and the deep layer had little changes. (4)The horizontal influence distance of gully on soil water content in catchment area was 1~3 m

for gully in catchment area

7 m for influence depth. It was suggested that drought-tolerant shrubs and herbs with low water consumption should be densely planted near the gully to increase the surface roughness and reduce the water flow velocity. And the plant roots could hold the soil and increase the anti-impact property to control gully erosion.
