中文摘要	结合野外采样和室内分析,对库布其8种防护林0~100 cm的土壤水分和0~60 cm的土壤养分进行分析.0-100 cm土壤水分随着土层深度逐渐增加,土层和防护林类型均对土壤水分有极显著影响,8种防护林样地的土壤水分从大到小依次为:旱柳+小美旱扬>旱柳>沙枣+沙柳>沙枣>速生杨>速生杨+羊柴>拧条>羊柴.对0~60 cm的土壤养分分析表明,土层对7个土壤养分指标均无显著影响,表土层0~10 cm土壤养分高于10~60 cm土层的,表现出土壤养分的表聚效应.防护林类型对7个土壤养分指标均有极显著影响,柠条和旱柳样地中土壤养分较高,羊柴样地中土壤养分相对较低.结果表明:旱柳、旱柳+小美旱杨和柠条等防护林对土壤的改良作用较好,土壤有较好的水分和养分条件,林下草本植被的物种多样性和盖度都较高,羊柴和速生杨防护林表明对流沙的改良作用较差,土壤水分和养分较低,林下草本植物的物种多样性和盖度均较低.
英文摘要	Combining the field sampling and laboratory analysis, soil water between 0-100 cm and soil nutrient between 0-60 cm of 8 kinds of shelter forest in the Kubuqi Desert were analyzed. Soil water gradually increased with the increase of soil depth. Soil layer and shelter forest type both had significant effect on soil water of a shelter forest. From being big to small, the soil water of 8 kinds of shelter forest were respectively: Salix matsudana + Populus popular’s, Salix matsudana, Elaeagnus angustifolia+Salix psammophila, Elaeagnus angustifolia, Populus Spp., Populus Spp. + Hedysarum fruticosum, Caragana korshinskii, Hedysarum fruticosum. The soil nutrient of the 0-60 cm soil layer showed that this layer had no significant effect on the soil nutrient and the topsoil (0-10 cm) nutrient was higher than deep soil (10-60 cm). Shelter forest type had a significant effect on the seven soil nutrient indexes. Soil nutrient of Caragana korshinskii and Salix matsudana were relatively higher and Hedysarum fruticosum was relatively lower in the 8 kinds of shelter forest. The results showed that Salix matsudana, Salix matsudana+ Populus popular’s and Caragana korshinskii could better improve the quicksand, not only having better water and nutrient conditions and also higher species diversity and vegetation coverage. Hedysarum fruticosum and Populus Spp. could decrease the quicksand, not only having worse water and nutrient conditions and also lower species diversity and vegetation coverage.
