摘要

智利的火山土壤,如andiols和Ultisols,覆盖了该国大部分可耕地,因其独特的矿物学特征而受到重视。本研究研究了从原始森林到森林农业系统的土地利用变化对四种火山土壤类型(acrudoxduraquand、Duric Hapludand、典型古生代和典型Hapludand)的成土作用的影响。形态分析表明,农业利用下的土壤除了有机层的损失外,还发生了土壤结构的变化。土壤的物理和化学性质,包括容重、土壤有机碳(SOC)、pH和可提取铝均存在显著差异。与原生林土壤相比,农田土壤土壤表现出较高的堆积密度、较低的有机碳和较低的可提取铝含量。主成分分析(PCA)表明,在某些情况下,土地利用之间存在明显的分离,这些特征部分丧失。矿物学分析检测到矾石、三水铝石、高岭石和羟基层间矿物;然而,没有直接证据表明结晶粘土矿物的变化是由土地利用变化引起的。此外,虽然未来的研究将受益于更精细尺度的土壤分类,以解释智利南部的地貌变异性,但目前的发现已经突出了土地利用变化对火山土壤成土作用的明显影响。关键词:火山土,土地利用变化,成土作用,土性,土壤矿物学

Effects of land-use change on morphological, physicochemical, and mineralogical properties of volcanic soils in southern Chile
Chilean volcanic soils, such as Andisols and Ultisols, cover much of the country’s arable land and are valued for their unique mineralogical characteristics. This study investigated the effects of land-use change from native forest to silvoagricultural systems on pedogenesis across four volcanic soil types: Acrudoxic Duraquand, Duric Hapludand, Typic Paleudult, and Typic Hapludult. Morphological analyses revealed that soils under agricultural uses have undergone changes in soil structure in addition to a loss in organic horizons. Significant differences were noted in physical and chemical properties, including bulk density, soil organic carbon (SOC), pH, and extractable aluminum. Andisols under croplands displayed higher bulk densities, lower SOC, and decreased extractable aluminum contents compared to those under native forests. Principal component analyses (PCA) revealed a distinct separation between land uses based on andic properties, suggesting, in some cases, a partial loss of these distinctive characteristics. Mineralogical analyses detected allophane, gibbsite, kaolinite, and hydroxy-interlayered minerals; however, no direct evidence was found for crystalline clay mineralogical transformations due to land-use change. Furthermore, while future studies would benefit from a finer-scale soil classification to account for the geomorphological variability of southern Chile, the present findings already highlight clear impacts of land-use change on pedogenesis in volcanic soils. Keywords: Volcanic soils, Land-use change, Pedogenesis, Andic properties, Soil mineralogy.
