摘  要：
旨在了解陕北黄土区枣林土壤物理性质的差异性以及林地土壤结构,以期为今后陕北黄土区枣林营造、区域林业经济发展和植被恢复提供参考依据。本研究以陕北黄土区神木市马镇乡枣林为主要研究对象,通过采用环刀浸水法对其土壤物理性质进行测定,通过对物理性质的空间分布特征进行分析。结果表明:(1)不同植被类型土壤物理性质存在显著差异(P<0.05),研究区不同植被类型土壤水分大小为草地>山地枣林>杏树林;最大持水量和毛管持水量大小为杏树林>山地枣林>草地;(2)研究区不同林龄河滩枣林土壤持水量和土壤孔隙度存在显著差异(P<0.05),20年生的河滩枣林持水性方面要较近100年生的河滩枣林好,但是20年生的河滩枣林土壤结构要较近100年生的河滩枣林差;(3)研究区山地枣林与河滩枣林土壤持水性和孔隙度呈显著差异(P<0.05),土壤容重则差异不显著(P>0.05);山地枣林与河滩枣林的土壤含水量都在60～100 cm达到最大,最大值分别是10.38%和19.65%。陕北黄土区枣林土壤物理性质和结构存在差异性。

摘  要：
To understand the differences in soil physical properties and soil structure of jujube forests in loess area of northern Shaanxi and provide references for jujube forest construction, regional forestry economic development and vegetation restoration, taking jujube forest in Mazhen, Shenmu as the main research object,we determined the soil physical properties by ring immersion method, and analyzed the spatial distribution characteristics of soil physical properties. The results showed that:(1) there were significant differences in soil physical properties among different vegetation types(P<0.05); the order of soil moisture was grassland>jujube forest in mountain>apricot forest; the maximum water holding capacity and capillary water holding capacity were apricot forest>jujube forest in mountain>grassland;(2) there were significant differences of soil water holding capacity and soil porosity of jujube trees of different forest ages(P<0.05); the water holding capacity of the 20-year-old jujube trees in beach was better than that of the 100-year-old jujube trees in beach, but the soil structure of the 20-year-old jujube trees in beach was worse than that of the 100-year-old jujube trees in beach;(3) the soil water holding capacity and porosity of jujube trees in mountain and beach were significantly different(P<0.05), and the soil bulk density was not significantly different(P>0.05); the soil water content of jujube trees in mountain and beach reached the maximum at soil layer of 60-100 cm, and their maximum values were 10.38% and 19.65%, respectively.
