- 摘要:
- 以黄土高原神木六道沟流域为研究对象，选取流域内3种典型植被类型（林地、草地、灌木）所处的3种侵蚀环境（梁峁顶、梁峁坡、沟坡）0—30 cm土层土壤，对土壤5种氮素（全氮、有机氮、矿化氮、铵态氮、硝态氮）对侵蚀环境的响应进行了研究。结果表明：（1）林地土壤全氮和有机氮含量最大，显著高于草地和灌木地，不同植被类型土壤氮素随侵蚀环境的变化规律不尽相同。（2）林地矿化氮和硝态氮含量高于草地和灌木地；灌木地铵态氮高于林地和草地。（3）土壤容重和pH与全氮、有机氮、矿化氮、铵态氮和硝态氮呈极显著负相关，有机碳和C/N与全氮、有机氮、矿化氮、铵态氮和硝态氮呈极显著正相关。（4）矿化氮占全氮的比例随全氮含量的升高而升高，铵态氮占氮的比例随全氮的升高而降低。通过不同植被类型土壤氮素对侵蚀环境的响应，能够长期为黄土高原农业生产、生态修复与重建提供科学依据。
- Abstract:
- Three typical vegetation types (forest grass, and shrub) in the three types of erosion environments (hilltop, hillside, and ravine slope), and 0—30 cm soil layers of forestland, grassland, and shrub land in Liudaogou watershed on the Loess Plateau of China were selected. The response of five fractions of soil nitrogen (total nitrogen, organic nitrogen, mineralizable nitrogen, ammonium nitrogen, nitrate nitrogen) to the erosion environment was studied. The results showed that: (1) the contents of total nitrogen and organic nitrogen in the forestland soil were the highest, which was significantly higher than those in grassland and shrub land, the contents of soil nitrogen in different vegetation types varied with erosion environments; (2) the contents of mineralizable and nitrate nitrogen in forestland were higher than those in grassland and shrub land; the ammonium nitrogen content in shrub land was higher than those in forestland and grassland; (3) soil bulk density and pH were significantly negatively correlated with total nitrogen, organic nitrogen, mineralizable nitrogen, ammonium nitrogen, and nitrate nitrogen; organic carbon and C/N were associated with total nitrogen, organic nitrogen, mineralizable nitrogen, and ammonium; there was a significant positive correlation between nitrogen and nitrate nitrogen. (4) The ratio of mineralizable nitrogen to total nitrogen increased with the increase of total nitrogen content, and the proportion of ammonium nitrogen in nitrogen decreased with the increase of total nitrogen. The response of soil nitrogen in different vegetation types to the erosion environments can provide scientific basis for long-term agricultural production, ecological restoration and reconstruction on the Loess Plateau.
