摘要:
 为探讨荒漠灌丛群落特征和土壤性状对放牧干扰的响应，以西鄂尔多斯广泛分布的霸王、沙冬青和四合木灌丛为对象，对3种放牧强度下灌丛生长及土壤养分进行比较研究。结果表明：1）放牧区灌丛覆盖度、平均冠幅、高度和基径显著低于轮牧区和围封区；2）牲畜对霸王和沙冬青灌丛的啃食主要发生在叶结构部分，而四合木灌丛主要啃食三级枝结构；不同放牧强度下根生物量和总生物量均为围封区＞轮牧区＞放牧区，围封区3种灌木总生物量分别为放牧区的1.78，1.98倍和1.84倍；3）各放牧强度下，3种灌丛土壤有机碳、全N和全P均随土层深度的增加显著减少，土壤容重随土层深度的增加而增大；4）放牧干扰显著降低表层土壤有机碳含量，3种灌丛均为放牧区显著低于围封区和轮牧区；轮牧区深层土壤（20～40、40～60 cm和60～80 cm）的全N含量显著高于放牧区和围封区；全P对放牧干扰的响应规律与有机碳和全N恰好相反，为放牧区显著高于围封区和轮牧区；放牧干扰后土壤容重的变化趋势为放牧区＞轮牧区＞围封区。综合来说，放牧会显著降低灌丛覆盖度、生产力、土壤养分和透气性，而轮牧和围封有助于植被覆盖度和各生长指标的恢复，并提高土壤固碳能力和对氮素的积累。因此不合理放牧是导致荒漠地区灌木植被退化的重要原因，合理的放牧制度可以有效提高荒漠灌丛生产力。
Abstract:
 In order to study the response of desert shrub community and soil characteristics to grazing disturbance,3 bush species (including Sarcozygium xanthoxylon,Ammopiptanthus mongolicus and Tetraena mongolica) widely occurring in Western Ordos were selected as the research objects to compare the shrub growth status and soil nutrient status under 3 grazing intensities,i.e.,enclosure,seasonal rotation grazing and uncontrolled grazing.The results showed that 1) the shrub coverage,average canopy,average height,and average branch diameter in uncontrolled grazing region were significantly lower than those of the other two.2) For S.xanthoxylon and A.mongolicus,livestock eating activity mainly occurred at the leaf structure,while for T.monglia,it mainly occurred at the tertiary branch structure.Under all 3 grazing intensities,both root biomass and total biomass were in the order of enclosed region>rotational grazed region>uncontrolled grazing region.The total biomasses of the 3 bushes in the enclosed region were 1.78,1.98,1.84 times higher than the grazing region,respectively.3) In each grazing intensity,the soil organic carbon,total nitrogen and total phosphorus had significantly negative correlation with the soil depth.Soil bulk density had positive correlation with the soil depth.4) Grazing disturbance significantly reduced the surface soil organic carbon content,all 3 species had lower organic carbon content in uncontrolled grazing region than the other two.In rotational grazed region,the deep soil (20-40 cm,40-60 cm,60-80 cm) total nitrogen content was higher than uncontrolled grazing region and enclosed region.The response of total phosphorus to grazing disturbance was in opposite to organic carbon and total nitrogen,the content was higher in uncontrolled grazing region than the other two.The change trend of soil bulk density after grazing disturbance presented the order of uncontrolled grazing region>rotational grazed region>enclosed region.In conclusion,uncontrolled grazing will significantly decrease the shrub coverage,productivity,soil nutrient and permeability,while rotational grazing and enclosure are beneficial for the recovery of shrub coverage and other growth indicators,moreover strengthen the soil carbon fixation ability as well as nitrogen accumulation.Therefore,unreasonable grazing is one of the dominant causes of vegetation degeneration of desert shrub,grazing system rationalization would effectively enhance the productivity of the desert shrub community.
