The present invention relates to a kind of vegetation-covered area soil copper inversion method based on blade measured spectra, steps are as follows: Step 1: image capturing and pretreatment；Step 2: spot sampling；Step 3: handling sample；Step 4: leaf spectra measurement and pretreatment；Step 5: soil sample copper content measurement；Step 6: vegetation index and spectral parameter calculate；Step 7: correlation analysis and parameter selection；Step 8: model construction；Step 9: large area inverting Soil Copper constituent content.Vegetation-covered area large area Soil Copper constituent content image can be obtained in the present invention, provides instruction information for Mineral Resource Survey and looks for mine clue, provides scientific basis for soil quality evaluation and soil comprehensive treatment.Meanwhile it can obtain heavy metal pollution of soil spread condition on this basis, by multi temporal analysis and control efficiency is evaluated.The present invention has many advantages, such as that detectable range is big, speed is fast, can real-time monitoring. |
