中文摘要	通过对不同放牧梯度下蒿类荒漠草地地上植物的高度、盖度、密度和生物量及地下土壤容重、全氮、全磷、全钾和有机质等指标的测定和分析,旨在为此类草地恢复和合理放牧制度的确立提供科学依据。结果表明:(1)不同放牧梯度下放牧后的草地植物的地上生物量下降十分为明显,放牧前、适度放牧后及重度放牧后分别为:161.98,105.11和73.17 g/m~2,草地植物生物量在不同牧压间的变化差异极显著(P<0.01);(2)适度放牧下,0~10、10~20及20~30 cm的土壤容重在放牧前后均差异不显著(P>0.05)。重度放牧下,10~20 cm土壤容重放牧后比放牧前增加,差异显著(P<0.05);(3)10~20和20~30 cm土层,全钾在适度放牧后和重度放牧后均表现为增加、有机质均有所减少,其放牧前后均差异显著(P<0.05)。
英文摘要	The effect of grazing intensities on plant communities and soil physical and chemical properties of artemisia desert grassland was studied by the measurement of plant height,coverage,density and biomass and soil bulk density,total nitrogen,total phosphorus,total potassium and organic matter in order to provide a scientific basis for the establishment of reasonable grazing system.Results showed that(1) the plant biomass obviously decreased after grazing under different grazing intensities,and it was 161.98 g/m~2,105.11 g/m~2 and 73.17 g/m~2 for zero grazing,moderate grazing and heavy grazing respectively.The biomass difference among grazing intensities was significant(P<0.01).(2) Under moderate grazing,the differences of soil bulk density in 0~10 cm,10~20 cm and 20~30 cm layers were not significant before and after grazing(P>0.05).Under heavy grazing,the soil bulk density in 10~20 cm layer significantly increased after grazing(P<0.05).(3) Within 10~20 cm and 20~30 cm layers,the total potassium content increased and organic matter content decreased after grazing in moderate grazing and heavy grazing treatments(P<0.05).
