陕北黄土区坡面微地形土壤水分的空间变异性分析对近自然植被恢复具有重要意义。对不同规模的缓台微地形土壤水分数据进行了测定和分析。结果表明:(1)面积大小不同的缓台土壤水分有着明显的差异
总体呈面积越大水分条件越好的趋势。(2)土壤水分变异系数在0-60 cm土层深度呈现:小规模缓台(
<
100 m
2
)> 大规模缓台(>1000 m
2
)> 中规模缓台(100~1000 m
2
)的规律
并且随着土层的加深
缓台土壤水分变异系数有减小的趋势。(3)在大规模缓台的内部
土壤水分在纵坡向上的变异系数要高于横坡向。通过对大规模缓台内部0-60 cm土壤水分数据做地统计学分析
球状模型被选为最优的半方差理论模型。由克里格插值生成的土壤水分分布图表明
在缓台与其上部陡坎微地形连接处的土壤水分条件要优于缓台其它部位的水分条件。
Spatial variability of soil moisture on micro-topography is an important factor influencing the distribution and restoration of vegetation on the Loess Plateau of China. Soil moisture of different size of platforms in loess hilly-gully region was investigated and analyzed. The results showed that: (1) The size of platform had a significant impact on soil moisture content. Overall
the larger platform showed a better soil moisture condition; (2) The variation coefficient of soil moisture in 0-60 cm soil layer of platforms ranked as follows: small size platform(<100 m2)> large size platform(>1000 m2)> medium size platform(100~1000 m2); (3) Within the large size platform
the variation coefficient of soil moisture along the up and down slope direction(parallel to slope) was higher than that along the contour. Geo-statistics was used to analyze the spatial heterogeneity of soil moisture(0-60 cm) in large size platform. A spherical model was used to fit the change of semi-variance with separated distance. Kringing interpolation showed that within the large size platform
soil moisture on the joint part of platforms and the scarp on upslope was higher than other parts.
