Research background and significance
The ground object spectrometer is an instrument that uses spectral technology to measure the characteristics of ground objects. It can measure and analyze the reflective characteristics and other characteristics of ground objects. It has a wide range of applications in many fields such as geographic information science, agricultural science, geophysics, etc., mainly used for ground object characteristic analysis and remote sensing data analysis.
Equipment application introduction
1. Ecosystem research: It helps to study the relationship between aquatic plants, animals and water environment in water ecosystems, understand the structure and function of water ecosystems, and provide scientific guidance for wetland protection and river ecological restoration.
2. Crop detection can quickly and accurately analyze the growth and development status, quality characteristics and pests and diseases of crops. It can effectively detect the variety, quality, growth status, etc. of crops, so as to better provide technical support for agricultural production.
3. Chlorophyll content monitoring: By analyzing the spectral characteristics of vegetation in the red and near-infrared bands, the chlorophyll concentration is inverted to judge the growth status of vegetation, such as whether the leaves are healthy and the intensity of photosynthesis. For example, vegetation with high chlorophyll content has strong absorption in the red band and strong reflection in the near-infrared band, based on which a relevant model can be established to estimate the content.
4. Leaf Area Index (LAI) Estimation: Use the correlation between spectral reflectance and leaf area index, combined with specific band combinations (such as near infrared and short-wave infrared) to evaluate vegetation
