This study presents a mechanism analysis to the response of leaf spectrum result from trace elements. A wide range of leaves were collected including variations in species and leaf status. The biochemistry composition was measured using ICP-AES techniques to determine Fe

Mo and B contents. Concurrently

leaf reflectance was measured with a high spectral resolution spectrophotometer in the 400-2500 nm range with approximately 1.1 nm spectral resolution. Trace elements are helpful to natural growth of vegetable

and the detection in trace elements’ status is an important approach to find out growth condition of vegetable. The study for trace element and spectral characters is one of important methods in quantitative remote sensing. In this paper

spectrum data and trace elements are firstly analyzed using different techniques

and in the end the relationship was studied between trace elements and leaf spectrum

and differential coefficient spectrum. Result shows that Co content is strongly correlative with leaf spectral relfectivity negatively in around 569.22 nm. In addition
