摘要

[目的

]

研究不同放牧强度对荒漠草原植被特征、土壤物理性能及其土壤侵蚀的影响，为荒漠草原水土流失治理和退化及生态系统修复提供科学依据。[方法

]

以内蒙古希拉穆仁荒漠草原为研究区，采用原位监测和模拟试验相结合的方法，对重度、中度、轻度和无放牧4种不同放牧强度样地的植被群落、土壤物理性质、土壤侵蚀过程开展了研究。[结果

]

①随着放牧强度的增加，群落平均盖度、高度和地上生物量呈降低趋势，物种丰富度指数、多样性指数及均匀度指数整体呈上升趋势。②土壤砂粒含量随放牧强度的增加呈上升趋势，表层土壤(0—10 cm)容重及入渗性能更易受放牧影响。③相同降雨强度下，随放牧强度的增加，土壤的侵蚀产沙量随之增加。土壤初渗速率、Simpson优势度指数和土壤砂粒含量是影响不同放牧强度下土壤侵蚀特征的关键因素。[结论

]

放牧显著影响荒漠草原植被群落特征及土壤水文物理性能，因此，建议该区放牧强度控制在中度(2羊单位/hm

)及以下，对于受重度放牧破坏的草原区，围栏封育的同时还可适当进行人工补播或利用微生物改良土壤来提升土壤抗蚀性。

Abstract

[Objective] The effects of different grazing intensity on vegetation features

soil physical properties

and soil erosion in a steppe desert were determined in order to provide a scientific basis for soil erosion control

degradation and ecosystem restoration in this region.[Methods] The vegetation community

soil physical properties

and soil erosion processes of sample plots under four different grazing intensities (heavy

moderate

light

and no grazing) were studied in the Xilamuren desert steppe of the Inner Mongolia Autonomous Region by use of in-situ monitoring and simulation experiments.[Results] ① Average coverage

height

and aboveground biomass of the vegetation community decreased as grazing intensity increased

while species richness index

diversity index

and evenness index increased. ② Sand content of the soil increased with grazing intensity

and bulk density and infiltration of the surface soil (0-10 cm) were more affected by grazing. ③ Under the same rainfall intensity

soil erosion and sediment yield increased with increasing grazing intensity. Soil primary infiltration rate

Simpson dominance index

and sand content in the soil were the key factors affecting soil erosion features under different grazing intensity.[Conclusion] Grazing significantly influenced the desert steppe vegetation community characteristics and soil hydro-physical properties. Therefore

grazing intensity should be controlled to moderate intensity (i.e.

two sheep units/hm2) or below. For steppe regions damaged by heavy grazing

soil erosion resistance can also be increased by soil improvement through the use of appropriate artificial reseeding and introduction of microorganisms.
