中文摘要	为明确荒漠草原疯草对发生区土壤性质的影响,通过野外调查取样和室内分析,测定了2种危害最为严重的疯草变异黄芪(Astragalus variabilis)和小花棘豆(Oxytropis glabra)发生地的土壤物理和化学性质。结果表明:变异黄芪和小花棘豆发生区与未发生区土壤质地、含水量、孔隙度和容重无显著差异,发生区土壤碱解氮显著增加;小花棘豆发生区速效磷增加,速效钾降低。变异黄芪和小花棘豆发生地土壤理化性状差异显著。前者土壤砂粒含量较高,而水分、碱解氮、速效磷、速效钾、有机质含量和pH则较低。变异黄芪和小花棘豆发生区土壤物理性质无明显改变,植物可利用养分有显著变化。变异黄芪比小花棘豆更能适应贫瘠的土壤条件,在荒漠草原潜在分布区面积大,更具危害性。
英文摘要	Astragalus variabilis and Oxytropis glabra are the most poisonous weeds in Inner Mongolia, and they do a huge damage in local livestock industry. In order to determine the effects of locoweed occurrence on the soil properties of A. variabilis and O. glabra habitats in desert steppe, soil physical and chemical properties in occurrence and non-occurrence plots were measured by field samples and indoor analyses. Results showed that there was no significant difference in soil texture,porosity,water content and bulk density between occurrence plots and control plots of both locoweeds,whereas the soil alkali-hydrolyzable nitrogen (N) contents of occurrence plots significantly increased that of compared control plots. Additionally, the occurrence plots of O. glabra exhibited the increase of available phosphorus (P) and the decrease of available potassium (K). Though both A. variabilis and O. glabra are distributed in the desert grassland of Tengri town in Alashan Zuoqi,the soil properties of their habitats have significant difference. A. variabilis grows in the soil with higher sand content than O. glabra,but the soil water, alkalihydrolyzable N,available P,available K, organic matter contents and pH value of A. variabilis habitat are significantly lower than that of O. glabra. Both A. variabilis and O. glabra do not cause the notable changes of soil physical properties. Compared with O. glabra weeds, A. variabilis weeds have stronger adaptability to environmental stress and considerable potential for future spread implying more serious damage to the livestock industry of desert grassland.
