摘要

以陕北黄土区吴起县合沟流域浅沟土壤水分为研究对象，通过对研究区不同深度、不同坡向、不同坡位的浅沟土壤水分空间分布特征进行研究。结果表明：（1）根据浅沟与原状坡油松生长量关系，将浅沟划分为深浅沟（40 cm ≤浅沟深度）和浅浅沟（20 cm ≤浅沟深度<40 cm）；（2）研究区浅沟土壤水分高于原状坡；浅沟土壤水分在0-60 cm土层聚集，原状坡则在0-40 cm土层聚集；（3）浅沟不同土层土壤水分变异程度不同，阳坡土壤水分变异性较阴坡小；20-60 cm土层中，浅沟土壤水分变异系数较大，土壤水分较活跃，其他土层变异系数较小，土壤水分较稳定；（4）不同坡位、不同坡向和不同深度的浅沟土壤水分存在显著差异；在浅浅沟中，土壤水分表现为下坡位 > 上坡位 > 中坡位；深浅沟则为上坡位 > 下坡位 > 中坡位；在浅沟内，阴坡在中、下坡位土壤水分显著高于阳坡，阳坡上坡位土壤水分则高于阴坡；原状坡阴坡土壤水分显著高于阳坡。

Abstract

The soil moisture of ephemeral gully in Hegou watershed at Wuqi county in Loess Area of Northern Shaanxi was taking as the research object. The spatial distribution characteristics of soil moisture in different ephemeral gullies with different depths

different slope aspects and different slope positions were studied. The results showed that:(1) According to the relationship between ephemeral gully and the growth of Pinus tabuliformis Carr. on the original slope

the ephemeral gully was divided into deep ephemeral gully (40 cm ≤ depth) and shallow ephemeral gully (20 cm ≤ depth <40 cm). (2) The soil moisture of the ephemeral gully was higher than that of the original slope; the soil moisture of the ephemeral gully was concentrated in the 0-60 cm soil layer

while that of the original slope was concentrated in the 0-40 cm soil layer. (3) The soil moisture variation degree was differeat in the different soil layers in ephemeral gully. The soil moisture variability of sunny slope was smaller than that of shady slope. In 20-60 cm soil layer

the soil moisture variability coefficient was larger

soil moisture was more active

and the soil moistures in other soil layers were less variable and more stable. (4) There were significant differences in soil moisture among ephemeral gullies with different slope positions

different slope aspects and different depths. In shallow ephemeral gully

soil moisture followed the order of lower slope > upper slope > middle slope

while in deep ephemeral gully

the order was upper slope > lower slope > mid slope. In ephemeral gully

soil moistures in the middle and lower position of the shady slope were significantly higher than that of sunny slope

and the soil moisture on the upper position of sunny slope was higher than that of shady slope. The soil moisture of the original shady slope was significantly higher than that of sunny slope.
