中文摘要	研究轮牧方式对草地土壤理化性质的影响,对草地科学利用和草地生态保护具有重要意义.以宁夏面积最大的荒漠草原为研究对象,通过放牧试验,研究围封禁牧、连续放牧、二区、四区和六区轮牧对040 cm土壤理化性质的影响,并运用模糊评判法对草地健康状况进行评价.结果表明:(1)六区和四区轮牧土壤粉粒含量和含水率较高;轮牧方式对土壤容重和孔隙度影响较小;四区和六区轮牧有利于土壤物理结皮、地衣藻类结皮维持.(2)连续放牧的土壤有机质含量最低,全氮含量以禁牧最低;速效氮含量在四区轮牧最高,六区轮牧下速效磷钾含量最高.(3)土壤性状间存在一定的相关性,但草地植物生物量与多数土壤性状相关性不明显.(4)六区轮牧的健康指数最高,连续放牧的健康指数最低.研究认为,研究区草原以六区轮牧为宜.
英文摘要	Studying the effects of rotational grazing on the physicochemical properties of grassland soil is of great significance for scientific utilization of grassland and ecological protection of grassland.Taking the desert grassland with the largest area in Ningxia as the research object,the effects of enclosure,continuous grazing,and rotational grazing on the physical and chemical properties of 040 cm soil were studied in the second,fourth and sixth districts through grazing experiments.Grassland health status was also evaluated by using evaluated method.The results showed that:(1)The silt content and moisture content of rotational soil in Sixth District and Fourth Region were higher.And the rotational grazing method had little effect on soil bulk density and porosity.The rotational grazing in Area IV and Region VI was prone to form soil physical crusts,lichen-algae Crust maintenance.(2)Continuous grazing had the lowest content of organic matter in the soil,and the total nitrogen content was the lowest in the grazing prohibition.The available nitrogen content was the highest in the four-area rotational grazing,and the available phosphorus and potassium contents were the highest in the six-area rotational grazing.(3)There were significant correlations between soil properties,but the correlation between grassland plant biomass and most soil properties was not obvious. (4)The health index of the six-region rotational grazing was the highest,and that of continuous grazing was the lowest.According to these findings,the grassland in the study area is suitable for rotation in six districts.
