- Title:
- Soil Organic Carbon and Distribution Characteristics of Carbon Fraction in Purple Soil in a Small Watershed of Ya’an Region
- Keywords:
- soil organic carbon; carbon fraction; purple soil

- 摘要:
- 以四川省雅安市和平小流域紫色土为研究对象，研究不同侵蚀强度紫色土小流域土壤有机碳分布特征。结果表明：自小流域上部向下部土壤侵蚀强度逐渐降低，土壤有机碳含量逐渐升高，且下部与上部和中部相比差异性极显著（P<0.05）；小流域内同一坡面不同坡位土壤总有机碳及碳组分含量均呈现坡脚>坡顶>坡中这一分布特征。小流域内阴坡和阳坡在土壤总有机碳及碳组分含量上有显著差异，具体表现为阳坡<阴坡。小流域内不同土层深度土壤总有机碳及碳组分含量均随土层的加深而降低。研究土壤碳的空间分布规律对该区退耕还林还草工程具有重要的指导意义。
- Abstract:
- Heping watershed with purple soil in Ya’an region was taken as study area. Distribution characteristic of soil organic carbon was studied under different erosion intensities. The results indicated that soil erosion intensity reduced and soil organic carbon content increased gradually from up to down of the watershed. Difference among up, mid and down of the watershed was significant (P<0.05). Total soil organic carbon (SOC) and the carbon fraction content in the foot of slope was the highest on the same slope, that was followed by the top and mid of slope. SOC and carbon fraction content in shady slope were higher significantly than that in sunny slope. Soil total organic carbon and the carbon fraction content reduced gradually with the increase of soil depth. Investigation on spatial distribution of soil organic carbon has the the key guidance in terms of Project of Returning Farmland to Forests or Pastures.
