摘要：以乌兰布和沙漠典型固沙灌木群落为研究对象,比较6种群落中0~150 cm土层的化学性质差异。结果显示:(1)各群落有机质均显著高于对照(P<0.05);白刺(Nitraria tangutorum Bobrov)+盐爪爪(Kalidium foliatum (Pall.) Moq.)群落在pH值、电导率等多项指标上表现最优;沙冬青(Ammopiptanthus mongolicus(Maxim. ex Kom.) S. H. Cheng)+白刺群落全氮最高;驼绒藜(Krascheninnikovia ceratoides(L.)Gueldenst.)群落碱解氮最高;霸王(Zygophyllum xanthoxylon (Bunge) Maxim.)群落全钾最高。(2)相关分析结果显示,pH值、电导率、有机质、全磷和速效磷与多项指标呈显著正相关。(3)土壤综合质量指数SQI评价中,白刺+盐爪爪群落的土壤质量最优,梭梭(Haloxylon ammodendron (C. A. Mey.) Bunge)+白刺群落和沙冬青+白刺群落次之,均显著优于其他群落及对照。此3种灌木群落在改善乌兰布和沙漠土壤质量方面具有显著优势,对沙漠生态恢复具有重要意义。
This study examined the chemical properties of soil in six sand-fixing shrub communities in Ulan Buhe Desert,focusing on the 0–150 cm soil layer.Results demonstrated that:(1)Soil organic matter content was significantly higher in all shrub communities than in the control site(BS)(P<0.05).The Nitraria tanguto-rum Bobrov+Kalidium foliatum(Pall.)Moq.community exhibited the most favorable pH and electrical conduc-tivity.The Ammopiptanthus mongolicus(Maxim.ex Kom.)S.H.Cheng+N.tangutorum community had the highest total nitrogen content,while the highest alkali-hydrolyzed nitrogen content was recorded in the Krascheninnikovia ceratoides(L.)Gueldenst.community.Total potassium levels were highest in the Zygophyl-lum xanthoxylon(Bunge)Maxim.community.(2)Correlation analysis revealed that pH,conductivity,organic matter,total phosphorus,and available phosphorus were significantly positively correlated with multiple soil quality indicators.(3)The soil quality index(SQI)evaluation identified the N.tangutorum+K.foliatum commu-nity as having the highest soil quality,followed by the Haloxylon ammodendron(C.A.Mey.)Bunge+N.tangutorum community and the A.mongolicus+N.tangutorum community,all of which exhibited significantly better soil properties than other communities and the control.These three shrub communities play a critical role in improving soil quality in the Ulan Buhe Desert and have substantial implications for ecological restora-tion efforts in arid environments.
