摘要: 为了解呼伦贝尔沙地不同植被恢复措施治理效果,掌握不同植被治理区土壤物理性质差异,为沙地治理实用技术提供合理建议,以呼伦贝尔沙地的羊柴(UH)、拧条锦鸡儿(UC)、樟子松(UP)、羊柴+披碱草+冰草(HEA)、樟子松+羊柴(HP)5种植被恢复措施为研究对象,以未做任何治理措施的流动沙地为对照(CK),测定各区域0~100 cm土层中土壤的含水量、容重、孔隙度等指标,并对比研究不同区域土壤物理性质差异特征。结果表明:1)UH、UC、HEA措施下的土壤含水量相对较高,分别较CK增加了121.90%、47.87%、44.96%,UH、UC、UP、HEA、HP 措施下的土壤饱和持水量均较CK有显著提高(P<0.05),分别增加了27.48%、3.57%、5.44%、7.37%、3.46%,且随土壤深度增加呈波动式变化;2)除了HP措施外,UH、UC、UP、HEA措施下的土壤容重与CK存在显著差异(P<0.05),分别降低了5.42%、3.01%、2.41%、1.81%,且随土层深度呈先减后增的趋势;3)UH、UC措施下的土壤孔隙度分别较CK增加了3.48%、2.47%,其他措施下的土壤孔隙度与CK无显著差异;4)通过隶属函数综合分析发现,单一灌木措施(UH、UC)、灌草结合措施(HEA)对治理区的整体恢复效果较好。

Abstract:

In order to find out the effect of different plant restoration measures in Hulun Buir Sandy Land,grasp the difference of soil physical properties in different plant management areas,and provide reasonable suggestions for practical technology of sand management,five plant restoration measures of Corethrodendron fruticosum(UH),Caragana korshinskii(UC),Pinus sylvestris var. mongolica Litv.(UP),Corethrodendron fruticosum+Elymus dahuricus+Agropyron cristatum(HEA),Pinus sylvestris var.mongolica Litv+Corethrodendron fruticosum(HP)in Hulun Buir Sandy Land were taken as the research objects,and the mobile sandy land without any control measures was taken as the control(CK).The soil water content,bulk density and porosity in 0-100 cm soil layer of each region were measured,and the differences of soil physical properties in different regions were compared.The results showed that:1)The soil water content under UH,UC and HEA was relatively high,which increased by 121.90%,47.87% and 44.96%,respectively,compared with CK.The soil saturated water-holding capacity under UH、UC、UP、HEA、HP was significantly higher than that of CK(P<0.05),which increased by 27.48%,3.57%,5.44%,7.37% and 3.46%,respectively,and fluctuated with the increase of soil depth.2)Except for HP measure,the soil bulk density under the other four measures(UH,UC,UP,HEA)was significantly different from that of CK(P<0.05),which decreased by 5.42%,3.01%,2.41% and 1.81%,respectively,and decreased first and then increased with soil depth.3)The soil porosity under UH and UC measures increased by 3.48% and 2.47%,respectively,compared with CK,and there was no significant difference between other measures and CK.4)Through the comprehensive analysis of membership function,it was found that single shrub measures(UH,UC)and shrub-grass combination measures(HEA)had better overall recovery effect on the control area.
