为评价植被恢复过程土壤基质改良对紫色土抗蚀性的影响,在湖南南部耒阳山地紫色土进行土壤基质改良试验,测定土壤基质未经处理(对照地)、表层与底层土置换(土层置换地)、表层与底层土置换并添加有机物改良剂(基质改良地)的紫色土0-10,10-20 cm土层13个抗蚀性评价指标,运用相关性分析和主成分分析方法筛选影响紫色土抗蚀性的主要指标,建立综合评价模型评价紫色土不同土壤基质处理后的抗蚀性。结果表明:(1)与对照地相比,基质改良地0-10,10-20 cm土层有机碳含量、抗蚀指数、>0.25 mm湿筛团聚体、>0.5 mm湿筛团聚体、

In order to evaluate the effect of soil matrix improvement on soil erosion resistance during vegetation restoration of purple soil,relevant experiments were carried out in the purple soil area of Leiyang in south Hunan Province,China.Three soil matrix types were chosen in our study,including the untreated purple soil matrix (control land),the purple soil of interchanging topsoil with subsoil(soil replacement land),and the one added organic improver based on the soil replacement land(soil matrix improved land).Thirteen erosion resistance evaluation indexes were determined,the important indexes ...
