Research on Calculated Model of C/N Ratio Change in Rice Leaf Under Condition of Cadmium Pollution in Soil Based on Spectral Response in Remote Sensing

摘要

C/N ratio of crops is an important input parameter of ecological model.Contamination stress will change the ecological parameters of crops,such as chlorophyll content and C/N ratio.Quite a few scholars chose the perspective of chlorophyll content inversion by remote sensing and build models of heavy metal contamination of remote sensing.But research on spectral stress response of C/N ratio is still blank.
