关于原始森林土壤及其生物元素状况和山地雨林林源性土地利用的研究很少（Rhoades et al. 2000）；到目前为止，大多数研究都集中在热带低地。牧场建立后，土壤理化特征和生物循环发生重要变化，影响土壤肥力以及土壤与大气和下游水生生态系统的相互作用（Reiners et al. 1994; Feigl et al. 1995; Koutika et al. 1997; Deborah et al. 2001; Cerri et al. 2003）。其中一些变化，如森林砍伐和放牧燃烧后pH值和交换性碱的增加，实际上是普遍的，发生在各种各样的地点和不同的土壤中。其他生物地球化学属性的变化，如土壤有机质周转量，变化更大，一些地区在牧场下增加，另一些地区则减少（Neill et al. 1998; Rhoades et al. 2000; Powers and Veldkamp 2005）。
There are only a few studies on soils and their bioelement status in primary forest and forest-derived land use for mountain rainforests (Rhoades et al. 2000); most investigations up to now have focused on lowland tropics. Important changes in physical and chemical soil characteristics and biological cycles follow pasture establishment and can affect soil fertility and the interaction of soils with atmosphere and downstream aquatic ecosystems (Reiners et al. 1994; Feigl et al. 1995; Koutika et al. 1997; Deborah et al. 2001; Cerri et al. 2003). Some of these changes, such as increase in pH and exchangeable bases that follow forest cutting and burning for pasture establishment, are practically universal and occur in a wide variety of sites and different soils. Changes to other biogeochemical attributes, such as soil organic matter turnover, are more variable increasing under pasture in some locations and decreasing in others (Neill et al. 1998; Rhoades et al. 2000; Powers and Veldkamp 2005).
