摘  要：
对内蒙古自治区锡林郭勒盟的羊草草原和大针茅草原长期围栏土壤的理化性质和腐殖质性质进行了研究。结果表明,围栏封育后,土壤容重下降,表面硬度减小,孔隙度和土壤毛管持水量增加;大针茅草原围栏封育样地土壤的有机质、全量养分和速效养分含量均有所增加;羊草草原围栏样地土壤的速效氮、速效磷含量增加,但有机质和全氮含量略有所降低。

摘  要：
The soil physical and chemical characteristic and humus characteristics in long term fencing soil from Leymus chinensis grassland and Stipa grandis grassland in Xilinguole League of Inner Mongolia Autonomous Region were studied.The results showed that soil bulk density and surface hardness were reduced and soil porosity and capillary capacity were increased after animal raising shut with fencing.The contents of organic matter,total nutrient and available nutrient in fencing soil from Stipa grandis grassland were all increased.The contents of available N and available P in fencing soil from Leymus chinensis grassland were increased,but the contents of organic matter and total N were decreased in some degree.
