3 Terms and definitions

The following terms and definitions defined in GB/T 36296-2018 and GB/T 39468-2020 apply to this document. 3.1 Leaf area index leafareaindex; LAI Half of the total area of the blade in the unit projected area of the ground. 3.2 Effective leaf area index effectiveleafareaindex The leaf area index equal to the observed porosity value under the assumption that the leaves are randomly distributed. Note. It can be obtained indirectly through optical instrument method measurement or remote sensing inversion. 3.3 Clumpingindex Describe the spatial distribution pattern of leaves in the canopy, which are randomly distributed, regularly distributed, and clustered in nature. 3.4 Elementary sampling unit; ESU The regional unit for leaf area index measurement deployed in the ground observation field. 3.5 Wireless sensor networks wireless sensor networks; WSN A network formed by freely organizing and combining sensor nodes through wireless communication technology.

4 Basic requirements

The authenticity inspection of the leaf area index remote sensing product should meet the requirements of Chapter 7 in GB/T 36296-2018, and meet the following requirements. a) When the inspection object is a single-day leaf area index remote sensing product, the difference in acquisition time between the reference object and the inspection object should be within 2 days; When the inspection object is a multi-day composite product of leaf area index, the acquisition time of the reference object should be in the composite product of leaf area index remote sensing. in time; ......
