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.
