摘要: 为探明退化程度对土壤物理性质及土壤微量元素的影响及其两者之间的关系,本研究以东祁连山山地草甸为研究对象,分析了4个不同退化程度(未退化-MND、轻度退化-MLD、中度退化-MMD和重度退化-MHD)山地草甸土壤物理性质和微量元素含量及其之间的关系。结果表明:随退化程度加剧,土壤饱和持水量、总孔隙度、毛管持水量、田间持水量和毛管孔隙度显著影响土壤Ca,Zn,Mg和Mn含量;土壤容重和土壤非毛管孔隙度显著影响着土壤Mo和Cu含量。退化程度显著影响着东祁连山山地草甸部分土壤物理性质以及土壤微量元素的分布,而土壤微量元素又受到部分土壤物理性质的影响,因此建议在未来考虑土壤微量元素的变化时将土壤物理性质的变化剔除,使得测得的土壤微量元素的变化值更加符合实际应用。

Abstract: This study investigated the effects of varying degradation degree on the physical properties of soil and its trace elements,as well as the relationship between them. This research was conducted on the mountain meadow of eastern Qilian Mountains,focusing on four distinct levels of degradation,non-degradation (MND),mild degradation (MLD),moderate degradation (MMD) and severe degradation (MHD). The results showed that soil saturated water holding capacity,total porosity,capillary water holding capacity,field water holding capacity,and capillary porosity significantly affected soil Ca,Zn,Mg,and Mn contents as degradation increased. Soil bulk density and soil non-capillary porosity significantly affected soil Mo and Cu contents. The degree of degradation significantly affected some soil physical properties and the distribution of soil trace elements in the meadow of the eastern Qilian Mountains,and the soil trace elements were affected by some soil physical properties. Therefore,it is suggested that the changes in soil physical properties should be removed when considering the changes in soil trace elements in the future so that the measured changes of soil trace elements are more in line with the actual application.
