摘要:如何提高石灰土中锰和磷矿质养分的植物利用效率，已成为喀斯特地区面临的重要问题。选取乌江流域９条石灰岩风化剖面，运用R型聚类分析和质量平衡法，研究了石灰岩风化过程中锰和磷迁移富集行为。结果表明，区内石灰土中锰和磷的富集程度远高于上陆壳、桂林石灰土和世界土壤。土壤中锰的富集是钙等易溶元素迁出以及锰从剖面上部淋滤到下部并沉淀的结果。磷在石灰土中的富集主要是钙等更易溶组分迁出的结果。研究区石灰土相对于桂林石灰土具有低pH值特征，相对于桂林石灰土、世界土壤和上陆壳具有低盐基度特征，其富集的锰和磷具有一定的迁移活性。图4表1参23

Abstract:How to improve phyto-availability of mineral nutrients Mn and P in calcareous soils has already become an important problem in karst areas. The study selected 9 limestone weathering profiles from the Wujiang Catchments，and investigated the mobility and enrichment behavior of Mn and P during limestone weathering with methods of R-type cluster analysis and mass balance calculation. The purpose of the study is to offer scientific references for cycle regulation of mineral nutrients such as Mn and P in karst areas. The results showed that our calcareous soils were rich in Mn and P relative to upper continental crust （UCC），Guilin calcareous soils（TS and MS） and world soil（WS）. The enrichment of Mn in our studied calcareous soils was a result of preferential leaching of other more soluble elements （e.g.，Ca） from the studied profiles and precipitation of supergene Mn in the lower part of the studied profiles. The enrichment of P in our studied calcareous soils was a result of preferential leaching of other more soluble elements such as Ca from the studied profiles. Our studied calcareous soils had lower pH values than those from MS，lower base cation contents than MS，WS and UCC implying that Mn and P in our studied calcareous soils have certain mobility. ［Ch，4 fig. 1 tab. 23 ref.］
