采用空间代替时间序列方法,选择立地基本相似的草本、灌草、灌丛、乔灌和乔木群落,调查了衡阳紫色土丘陵坡地不同恢复阶段土壤团聚体特征及其主要影响因子,并用典范相关分析和主成分分析对二者的相互关系进行定量分析。结果表明: 随恢复进行,土壤中大粒级团聚体含量显著增加(P5 mm粒级团聚体在土壤团粒结构中占主导地位,约占50%~80%,其次是5~2 mm含量,约占10%~ 15%; 随土层加深,草坡、灌草和乔灌群落的团聚体总量显著减小(P

Five types of plots, grass (GS), frutex and grass (FG), frutex (FX), arbor and frutex (AF), and arbor (AR) communities, were selected to study the properties of soil aggregates in different revegetation stages and their main influencing factors of purple soils on sloping land in Hengyang, Hunan Province, China by using spatial series instead of time series. The five communities in purple soils on sloping land were similar in site conditions, and denoted as five different successive stages. The relationships between the properties of soil aggr...
