| 摘 要： | 于2002年8月在内蒙古四于王旗对不同圈栏年限冷蒿-小禾草放牧草原土壤理化性状进行了研究。结果表明:围栏草地植物群落特征与土壤性状都优于全午放牧草地。随着围栏时间的增加,植物群落特征发生了变化,土壤的理化性状也相应地发生了一定的变化,但不如植被变化明显。土壤性状对植物群落特征变化的响应程度表现为土壤水分含量与客重最为敏感,土壤养分含量较为敏感,而土壤机械组成则最不敏感。

| Abstract: | The experiment was conducted in Artemisia firigida rangelands in Siziwang County in Inner Mongolia in August 2002. The study included community characteristics and soil properties. The results showed that plant community characters and soil properties of enclosed grasslands were better than those of all-year grazed grassland. With the increase of enclosing time, plant community characters changed, soil properties also changed accordingly, but the changes were not significant like that of vegetation. With the increase of enclosing time, the responsive degree of soil properties to the change of plant community characters was: water contents and bulk densities > nutrient contents > mechanical compositions. |
