| Summary: | This paper uses remote sensing technology to estimate the content of soil organic matter. It samples the soil, test its organic matter content, and analyzes the correlation between the reflectance of bands of various wavelengths and the content of organic matter in the soil with modern remote sensing technology. It figures out changes of soil organic matter content in different forms, and on which basis, determine the sensitive band of organic matter and construct an estimation model for the estimation of soil organic matter content at multi bands and single band. It finds that there is a close relationship between soil organic matter content and each band, and the estimation model is sound in stability and accurate measurement. As the application of remote sensing technology can improve the accuracy of the estimation of soil organic matter content, it is worth promotion and application.
