西藏土壤有锌含量及其影响因子分析
Analysis on Soil Available Zinc Content and Its Influencing Factors in Tibet
摘要
Abstract
The change of soil available zinc content and its influencing factors were studied according to analysis data on available zinc in 164 soil profiles from 18 tested soil types in Tibet. TheResults showed that the average contents of available zinc in surface and subsurface layer soil were about 3.0 and 1.0 mg/kg resp.. The content of available zinc in surface soil of different soil types in order was mountain humid forest soils (4.88 mg/kg) > alpine meadows soils (3.72 mg/kg) > valley semi-hydromorphic soils (2.25 mg/kg) > mountain drought forest-coppice soils (2.20 mg/kg) > frigid frozen soils (1.61 mg/kg) > alpine steep soils (0.82 mg/kg). The first principal influencing factor on effectiveness of zinc in Tibeta soils was organic matter content and the second principal influencing factor was pH value.关键词
