| 摘 要： | 研究了内蒙古风蚀沙化区退化草原植被恢复或重建过程中灌丛对养分的聚集和土壤肥力的保护作用,结果表明灌丛大小和灌丛不同土层养分含量没有明显的变化趋势,灌丛内0~5 cm土层的养分含量高于相应的对照样地,5~20 cm土层有机质和速效氮含量高于相应的对照,灌丛土壤颗粒含量和本地区土壤本底颗粒组成有密切的关系,和对照区相比,短期内没有显著增加土壤的细粒成分,但灌丛在减少风蚀方面具有一定的作用。

| Abstract: | In this paper, the role of shrub - coppices on accumulation of soil nutrients and conservation of soil fertility was studied during the restoration and reconstruction of degenerate grassland vegetation in wind - erosion and desertification district in Inner Mongolia. The results showed that there was no obvious change for size of shrub and nutrient content in different soil level of shrub. In shrub - coppices, nutrient content in 0 - 5 cm soil level was higher than the corresponding check plot. The content of organic matter and quick - acting nitrogen in 5 - 20 cm of soil wasnt increased obviously in short time. But the shrub - coppices could decrease wind erosion. |
