Soil environmental quality in Nanling commodity grain base based on equal intercept transformation radar chart

Abstract This paper introduces for the first time equal intercept transformation radar chart—an improved form—to assessment of soil environmental quality Nanling commodity grain base. The chart, a visual graphical data analysis method, translates from numerical to format. visualization enables presentation, process and results stick out mile is capable fully retaining information contained in excavating it depth geometry. Moreover, overcomes pertinently main defect conventional chart that evaluation result depends heavily on order arrangement indicators. indicated at depths 0–60 cm low mountain area base was second grade, while hilly plain areas were both grade. indicators poor exogenous Cd endogenous As; those As Hg; Cd. line with actual situation study area.
