Evolution of soil anti-erodiblity of Robinia pseudoacacia L. plantation at different ages in Hilly-gully region of Loess Plateau

open access: yes, 2010
采取时空互代法,以黄土丘陵区不同林龄的人工刺槐林为研究对象,选取坡耕地为对照,分析土壤抗蚀性的变化过程,并在此基础上提出土壤抗蚀指数。结果表明,黄土丘陵区坡耕地种植刺槐林后:>0.25 mm土壤水稳性团聚体、>0.5 mm土壤水稳性团聚体、平均质量直径、有机碳含量较坡耕地显著增加,并随林龄增加逐渐升高;土壤团聚状况、团聚度显著高于坡耕地并随林龄增加先降低后升高;土壤结构破坏率、分散系数和分散率呈波动式降低;小粒径的微团聚体和机械组成逐步向大粒径转变。相关性分析表明:>0.25 ...
