摘要：为了探究不同带状格局植被土壤水分物理性质的差异,通过选取我国北方12种典型植物篱并对其土壤水分物理性质的主要指标进行对比分析.结果表明：（1）植物篱系统内各部位土壤持水性能、毛管孔隙度、总孔隙度和机械组成差异不显著（p＞0.05）;黑土区和风沙土区植物篱系统内各部位土壤水稳性微团聚体（粒径＜0.25 mm）、小团聚体（粒径0.25～2.00 mm）、大团聚体（粒径＞2.00 mm）和团聚体总量差异显著（p＜0.05）,其中微团聚体（粒径＜0.25 mm）、大团聚体（粒径＞2.00 mm）和团聚体总量均为带内最高;风沙土区与黄土区植物篱系统内各部位土壤有机质含量差异不显著（p＞0.05）;黑土区植物篱系统内各部位土壤有机质含量差异显著（p＜0.05）,其中带内是带前的1.48倍,带后的1.42倍、带间的1.72倍.（2）不同植物篱系统整体问土壤持水性能、孔隙度、水稳性团聚体和有机质含量差异显著（p＜0.01）.土壤最大持水量、毛管持水量、田间持水量、毛管孔隙度和总孔隙度均表现为黄土区植物篱＞风沙土区植物篱＞黑土区植物篱;土壤微团聚体、小团聚体、大团聚体和团聚体总量均为黑土区最高,风沙土区最小;有机质含量表现为黑土区植物篱＞黄土区植物篱＞风沙土区植物篱.（3）不同植物篱系统整体间土壤机械组成差异显著（p＜0.01）.粘粒含量为黄土区植物篱＞黑土区植物篱＞风沙土区植物篱;粉粒含量为黑土区植物篱＞黄土区植物篱＞风沙土区植物篱;砂粒含量为风沙土区植物篱＞黄土区植物篱＞黑土区植物篱.（4）对12种植物篱系统整体进行聚类,按土壤类型不同可分为三类,即黄土区植物篱（甘肃定西和宁夏彭阳）、风沙土区植物篱（内蒙赤峰）、黑土区植物篱（黑龙江拜泉）.
In order to study the effects of banded vegetation pattern on soil moisture-physical properties, we analyzed and compared soil moisture-physical properties under 12 types of typical hedgerow systems which were planted in different modes in northern China. The results showed that： （1）Soil water-holding capacity, capillary porosity, total porosity and mechanical composition did not vary significantly among different parts of hedgerow systems（p〉0.05）. In black soil area and wind-sand area, the contents of water stable micro- aggregates（〈0.25 mm）, small aggregates（0. 25～2. 00 mm）, macro-aggregates（〉2. 00 mm） and total aggregate content significantly differed among different parts of hedgerow systems（p〈0.05）, which were all at the highest level in inner-band area except the content of small aggregates（0.25～2.00 ram）. In wind-sand area and loess area, the content of soil organic matter did not differ among different parts of hedgerow systems（p〉0. 05）. However, significant differences in the content of soil organic matter were observed among different parts of hedgerow systems in black soil area（p〈0. 05）. In inner band area of hedgerow systems, the content of soil organic matter was 1. 48,1. 42, 1. 72 times of those in front of hedgerows, behind hedgerows and between hedgerows, respectively. （2） Significant differences existed in soil water holding capacity, porosity, water-stable aggregates and organic matter among different hedgerow systems（p 〈0.01）. Under hedgerow systems in different area, soil water-holding capacity, capillary water capacity, field capacity, capillary porosity and total porosity all listed in the following order： Loess area〉wind-sand area〉black soil area, while the contents of soil micro-aggregates, small aggregates, macro aggregates and the total aggregate content, as well as soil organic matter content, were the highest in black soil area and the lowest in wind-sand area. （3）Significant differences existed in soil mechanical composition among different hedgerow systems （p〈0. 01）. Under hedgerow systems in different area, soil clay content listed in the following order： Loess area〉black soil area〉wind-sand area, while silt particle content followed the order： Black soil area〉loess area〉wind-sand area, and sand content followed the order. Wind-sand area〉loess area〉black soil area. （4）According to the results of cluster analysis, we can divide 12 types of hedgerow systems into three categories based on soil types, which were hedgerows in loess area（Dingxi of Gansu province and Pengyang of Ningxia Autonomous region）, wind-sand area （Chifeng of Inner Mongolia Autonomous region） and black soil area（Baiquan of Heilongjiang province）.
