梯田侧壁显著影响黄土塬区梯田土壤水分空间分布

Shuitu Baochi Xuebao
[目的] 坡地改梯田是黄土塬区重要的水土保持和农业措施,明确梯田侧壁(梯壁)对梯田土壤水分空间分布的影响有助于保持梯田水分,提高梯田生产力。[方法] 通过对黄土塬区典型人工高坡(梯壁高5 m)梯田不同位置土壤取样测定含水量和土壤物理化学性质,分析梯田土壤水分的空间分布特征和影响因素。[结果] 随着距梯壁距离的增加,梯田0—300 cm土层土壤储水量从15.9 mm增加至328.6 mm,呈显著上升趋势;梯壁蒸发量从318.0 mm逐渐降低至83.4 mm;梯面宽为300 cm时 ...

石漠化坡地不同整地措施下表层土壤水分空间分布特征

Shuitu Baochi Xuebao
[目的] 分析石漠化坡地不同整地措施下表层土壤水分的空间分布特征,为提高石漠化坡地的水资源利用效率和农业管理水平提供参考依据。[方法] 以石漠化坡地中反坡、斜坡和平地3种整地措施下的柑橘林地为研究对象,采用经典统计学、地统计学和多重分形理论研究土壤水分的空间分布特征。[结果] (1)反坡的土壤含水量显著高于平地和斜坡(p＜0.05),平地土壤含水量的空间连续性和聚集性以及总变异和结构性变异强于斜坡和反坡。(2)不同整地措施下的土壤含水量均具有中等强度变异性(10.00%≤CV≤100.00 ...
