摘  要：
[目的]阐明晋西黄土区典型人工植被类型对球囊霉素相关土壤蛋白(GRSP)和团聚体稳定性的影响,以及两者之间的关系,为黄土高原地区人工植被建设与管理提供科学依据。[方法]选取晋西三川河流域4种典型人工植被(苜蓿、刺槐、侧柏和核桃),以农地为对照,分析0—100cm土层中GRSP组分、有机碳(SOC)和团聚体稳定性指标在不同植被类型下的分布差异及其相关性。[结果]不同植被类型下易球囊霉素(EE-GRSP)、总球囊霉素(T-GRSP)以及两者的比值在0—30cm土层存在显著差异,均以核桃地最高,而苜蓿地较低。不同植被下EE-GRSP/SOC和T-GRSP/SOC均随着土层深度增加而增加,分别为1.78～6.77,4.07～19.11。与农地相比,侧柏和苜蓿地分别增加了39.67%,36.62%的EE-GRSP/SOC以及39.25%和46.70%的T-GRSP/SOC,而核桃分别减少了31.07%和36.93%。平均重量直径与T-GRSP和SOC呈显著正相关关系,而与EE-GRSP/SOC呈显著负相关关系(p<0.05)。[结论]不同人工植被对表层土壤GRSP的组分有明显影响,土壤团聚体稳定性不仅与GRSP的组分有关,也与其对SOC的贡献有重要关系。

摘  要：
[Objective]The objective of the study was to elucidate the effects of representative artificial vegetation types on soil glomalin-related soil protein(GRSP)and aggregate stability,and to evaluate the relationship between the latter two factors on the Loess Plateau in Western Shanxi Province in order to provide basic data for artificial vegetation restoration project.[Methods]Four representative artificial vegetation types,Medicago sativa,Robinia pseudoacacia,Platycladus orientalis,and Juglans regia,were selected in the Sanchuan River Basin,western Shanxi Province,with a cropland as the control.Soil samples were taken from a depth of 0—100cm to analyze the distribution differences of easily extractable-GRSP(EE-GRSP),total-GRSP(T-GRSP),soil organic carbon(SOC),and aggregate stability among different vegetationtypes.The relationship between these parameters were evaluated by Pearson analysis.[Results]The EE-GRSP and T-GRSP concentrations and the EE-GRSP/T-GRSP ratio significantly differed in the 0—30cm surface soil across different vegetation types,with the highest and lowest values being found in the J.regia and M.sativaplots,respectively.Both the EE-GRSP/SOC and T-GRSP/SOC ratios always increased with the increase of soil depth,having ranges of 1.78～6.77 and 4.07～19.11,respectively.The EE-GRSP/SOC and T-GRSP/SOC increased in the P.orientalis(39.67% and 36.62%)and M.sativa(39.25% and46.70%)plots as compared with the ones in cropland,while they decreased in the J.regia plot(31.07%and 36.93%).Mean weight diameter was positively correlated with T-GRSP and SOC(p<0.05)and negatively correlated with EE-GRSP/SOC(p<0.05).[Conclusion]Different artificial vegetation types considerably influenced GRSP components in the surface soil.Soil aggregate stability was not only related to the concentration of soil GRSP components,but also to their contribution to SOC.
