AB  - Vegetation leaf area index (LAI), also known as leaf area coefficient, can characterize the absorption and interception of light by vegetation and vegetation growth. It is usually defined as the sum of vegetation leaf surface area contained in unit area. Because the index can reflect the density of vegetation leaves and the growth status of vegetation in the study area, it is very important to accurately obtain Lai. In the acquisition process of Lai, remote sensing information technology is widely used because of its significant advantages of real-time dynamic and effective monitoring of vegetation characteristics and short operation cycle. This technology lays a foundation for the effective study of vegetation biochemical parameters.
