中文摘要	以短花针茅荒漠草原不同植被恢复模式的天然草地为对象,研究草地地上部分生物量及不同土层深度土壤水分的变化,分析地上部分生物量与土壤含水量之间的关系。结果表明:围栏封育+灌木条带+施肥复壮、围栏封育+松土补播+草种包衣2种荒漠草原植被恢复模式草地地上生物量在生长末期分别比放牧天然草地,增加31.30 g/m~2、24.57 g/m~2;3种植被恢复模式及放牧样地的表层(0~20 cm)土壤含水量均较低,随着深度增加,土壤含水量增大;短花针茅荒漠草原地上生物量与土壤含水量间呈正相关关系,围栏封育+灌木条带+施肥复壮、围栏封育+松土补播+草种包衣试验样地、放牧天然草地(CK)的地上生物量与0~20 cm土壤含水量呈显著正相关(P<0.05),围栏封育+灌木条带+施肥复壮试验样地的地上生物量与20~40 cm土壤含水量为极显著正相关(P<0.01);退化荒漠草原生态恢复过程中,可采取围栏封育、施肥、补播、增加防护灌木带等多种措施以提高生态恢复效果。
英文摘要	The influences of different vegetation restoration models on the grassland aboveground biomass and soil moisture were studied and the relationship between the aboveground biomass and soil water content were analyzed in Stipa breviflora desert steppe.The results showed that aboveground biomass significantly increased in two vegetation restoration models ofenclosing+shrub planting+fertilizing’andenclosing+reseeding+ seed coating’.The aboveground biomass of two vegetation restoration models increased by 31.30 g/m~2 and 24.57 g/m~2 respectively compared with that of grazing natural grasslands at the end of growth period.The surface soil water content of all samples was low and the soil water content increased obviously with the increase of depth.There was a significant positive correlation between aboveground biomass and soil water content in 0 to 20 cm layer in vegetation restoration models and grazing land(P<0.05).The above ground biomass ofenclosing+ shrub planting+fertilizing’model was significantly positively correlated with the soil water content in 20 to 40 cm layer(P<0.01).The degraded grassland could be restored by means of fencing,fertilizing and replanting. The shrub belt improved the ecological restoration efficiency.
