中文摘要	为了揭示陕北山地密植红枣林土壤水分空间分布状况,对枣林株行间不同位置(株间、行间、中心点)0～200 cm土层的土壤水进行了连续观测。结果表明:在7～9月,枣林地株间土壤水分状况明显好于行间。株间、行间、中心点土壤含水量均值分别为9.77%、7.66%、7.52%。不同降雨量下枣林地株行间不同位置土壤水分的累计入渗量不同,株间入渗量大于行间,且随着降雨量的增大,各位置入渗量也随之增大,株间的入渗补给作用在增强,但行间的入渗补给作用在减弱。中雨(p=14.8 mm),株间、行间、中心点累计入渗量分别为13.5、8.8、8.4 mm;大雨(p=31.6 mm),株间、行间、中心点累计入渗量分别为30.9、16.5、12、8mm。雨后枣林地株行间不同位置土壤水分日均消耗量以株间最大,达4.09 mm/d,行间次之,为3.77 mm/d,中心点最小,为2.27 mm/d。
英文摘要	In order to reveal the characteristics of spatial distribution of soil moisture in the close planting Jujube forest in Northern Shaanxi Province, cont inuous monitoring of soil moisture in 0~ 200 cm soil layer was carried out in different positions ( inter-tree, inter-row and center-point) of the Jujube forest. The results indicated that soil moisture of inter-tree was significantly better than inter-row in July~ September. The average soil water of inter-tree, inter-row and center-point was 9. 77%, 7. 66% and 7. 52% . With the changing of rainfall, cumulative infiltration was different in various positions of the Jujube forest. The infiltration capacity of inter-treewas larger than that of inter-row. With the increase of rainfall, the infiltration capacity increased in all positions and the infiltration was recharged. The function in inter- tree increased, but that in inter-row decreased. For example, in the moderate rain ( p = 14. 8 mm) , the infiltration capacity of inter-tree, inter-row and center-point was 15. 5 mm, 8. 8 mm and 8. 4 mm; while in the heavy rain ( p = 31. 6 mm) , that was 30. 9 mm, 16. 5 mm and 12. 8 mm, respectively. The average daily consumption of soil water in inter-tree was the highest ( 4. 09 mm/ d) , followed by that in inter-row ( 3. 77 mm/ d) , and that in center-point was the lowest ( 2. 77 mm/ d) in all positions.
