中文摘要	本试验以短花针茅 (Stipa breviflora) 荒漠草原淡栗钙土为研究对象,分析地形、放牧强度对土壤胡敏酸、富里酸和胡富比的影响,并探讨了土壤胡敏酸、富里酸与土壤有机碳的关系。结果表明,淡栗钙土胡敏酸和富里酸含量均较低,随着海拔上升,土壤胡敏酸和富里酸均有降低趋势,随放牧强度的增大土壤胡敏酸和富里酸均显著降低 (P<0.05) 。随海拔上升,其胡富比值降低,放牧强度影响胡富比值,其中重度放牧对胡富比值影响显著 (P<0.05) 。随着海拔上升,腐殖酸的各组分与有机质间的相关性增加,随放牧强度的增大其腐殖酸的各组分与有机质间的相关性降低。研究区适合轻度放牧,而且围栏放牧时,根据地形部位的不同,载畜率也应不同。
英文摘要	In this experiment,the effects of terrain and grazing intensities on soil humic acid (HA),fulvic acid (FA) and the ratio of HA/FA in the light chestnut soil samples from Stipa breviflora desert steppe were analyzed and the relationship between soil humic acid,fulvic acid and soil organic carbon were discussed.The results showed that the contents of HA and FA in light chestnut soil were lower.Both HA and FA decreased with altitude rising and significantly decreased (P <0.05) with the grazing intensity increasement.With altitude rising,the ratio of HA/FA in soil decreased.The graze intensity had effects on the ratio of HA/FA in soil and the heavy graze had significant impacts (P<0.05) on the ratio of HA/FA in soil.With altitude rising,the correlation between each composition of soil humic and organic matter increased with altitude rising and decreased with the grazing intensity increasement.These results suggested that the studied region was suitable for lightly grazing and the stocking rate should be adjusted according to the different terrain.
