摘要

为对臭柏群落土壤水分空间分布特征进行初步研究，以毛乌素南缘神木大保当镇臭柏（Sabina vulgaris Ant.）群落为研究对象，选取10个样地利用环刀进行土壤取样，通过土壤烘干法测出土壤含水量与蓄水量并进行分析。结果表明：（1）在坡位影响下，各样地间的土壤含水量存在显著性差异（P<0.05），含水量和蓄水量整体分别表现为沙丘下部 > 沙丘中部 > 丘间低地 > 沙脊，沙丘中部 > 沙丘下部 > 丘间低地 > 沙脊；（2）在坡向影响下，各样地的土壤含水量存在显著性差异（P<0.05），含水量和蓄水量均表现为背风坡>迎风坡；（3）在林内外植被影响下，各样地的土壤含水量存在显著性差异（P<0.05），含水量和蓄水量均表现为草地 > 臭柏 > 沙地。表明臭柏群落对土壤水分空间分布有一定的影响。

Abstract

In order to study the spatial distribution characteristics of soil moisture in Sabina vulgaris Ant. community

this paper took the vegetation of Sabina vulgaris Ant. in the southern edge of Mu Us as the research object. Ten plots were selected and soil samples were taken by cutting ring. The soil moisture content and water storage were measured and analyzed by soil drying method. The following results were obtained:(1) There were significant differences among the soil moisture contents in the plots with different slope positions (P<0.05). Soil moisture content and water storage were lower of dune > middle dune > lowland among sandy dune > sand ridge

middle dune > lower of dune > lowland among sandy dune > sand ridge. (2) There were significant differences among soil moisture contents under different slopes (P<0.05). Both soil moisture content and water storage showed that leeward slope>windward slope. (3) There were significant differences among soil moisture contents under the influence of vegetation inside and outside the forest (P<0.05). Both soil moisture content and water storage were grassland > Sabina vulgaris Ant. > Sand. These results showed that Sabina vulgaris Ant. Community had certain influence on spatial distribution of soil moisture.
