摘要:
植被是影响土壤有机碳含量和土壤结构的重要因素，植被通过凋落物影响有机碳输入的数量和质量，同时有改善土壤结构特别是水稳性团聚体的数量。探讨黄土高原侵蚀地区植被恢复后对土壤有机碳、氮及其团聚体平均重量直径的影响，研究结果显示土壤有机碳、全氮含量与水稳性团聚体平均重量直径的变化趋势相同，平均重量直径与有机C含量之间有二次多项式关系。植被类型是影响土壤碳、氮含量的关键因素，植被恢复增加土壤养分含量，改善土壤结构和土壤环境。
Abstract:
Vegetation is one of important factor to affect the content of soil organic carbon and aggregate, which increase the input of soil organic carbon and improve soil structure. The influence of vegetation restoration on distribution of aggregate and organic carbon and nitrogen in Loess Plateau was studied. The result showed that there was the same tendency in changes of soil organic carbon, nitrogen and mean weight diameter of aggregate (MWD), but there was quadratic correlation between the organic carbon and MWD. Vegetation restoration could be the best way to improve ecological environment.
