[目的] 探讨不同草地利用方式下粒度与有机碳含量及相关性,揭示草地退化过程当中土壤有机碳的损失速率,为科尔沁沙地生态环境恢复治理提供科学依据。[方法] 以科尔沁沙地乌力吉木伦河流域流动和半固定风沙土为研究对象,对流域内围封草地、不同退化程度的盐碱化样地和人工种植牧草样地等不同草地利用方式下粒度与有机碳含量及相关性进行了探索研究。[结果] 围封措施在控制土壤侵蚀和提高土壤有机碳含量方面均起到显著的作用;流域内0—20 cm土层各样地粒度组成以粉粒和砂粒为主,由于翻耕的因素,燕麦和苜蓿样地表层土壤粗粒化明显且比其他样地具有更高的峰值和中值粒径;研究区内100 μm粒径左右颗粒为易受侵蚀颗粒;土壤中小于100 μm颗粒组分每被吹蚀1%,其有机碳含量将损失0.120 4 g/kg。[结论] 在丘间平地分布的盐碱化草甸土地,根据实际情况结合围封措施和种植牧草能防止土壤侵蚀且有效提高有机碳含量。
[Objective] The relationship between soil particle size and organic carbon under different grassland use patterns was studied
to reveal the loss rate of soil organic carbon in grassland degradation process
in order to provide a scientific basis for the restoration and control of ecological environment in Horqin sandy land.[Methods] Taking the flow and semi-fixed aeolian sandy soil in the Wulijimulun River basin of Horqin sandy land as the research object
the relationship between grain size and organic carbon content was studied under different grassland utilization modes
such as the enclosed grassland in the basin
the salinization plots with different degrees of degradation and the artificially planted pasture plots.[Results] The enclosing measures played a significant role in controlling soil erosion and increasing soil organic carbon content. In the 0-20 cm soil layer of the watershed
the grain size composition was dominated by silt and sand. Due to the factors of tillage
the surface soil in oat and alfalfa plotswas coarser
and had higher peak and median grain size than other plots. In the study area
the particles with a size around 100 μm were easily to be eroded. For the soil particles with a size less than 100 μm
the organic carbon would be lost by 0.120 4 g/kg for every 1% wind erosion.[Conclusion] The saline-alkaline meadow land distributed in the hills can be combined with the enclosure measures and planting grasses
to prevent soil erosion and effectively increase the organic carbon content.
