Abstract

The invention discloses a method and a device for determining grassland aboveground biomass and a storage medium. The method comprises the steps: determining a pixel set corresponding to a preset area on the grassland, wherein the pixel set comprises a plurality of pixels corresponding to the preset area; selecting a to-be-evaluated pixel for evaluating the above-ground biomass from the pixel set; determining remote sensing surface energy feature information corresponding to the to-be-evaluated pixel according to the surface reflectance remote sensing data and the thermal infrared remote sensing data corresponding to the pixel set, wherein the remote sensing surface energy feature information is used for evaluating the above-ground biomass; and determining the above-ground biomass corresponding to the to-be-evaluated pixel according to the remote sensing surface energy feature information.

Description

technical field [0001] This application relates to the field of remote sensing science and technology, in particular to a method, device and storage medium for determining aboveground biomass of grasslands. Background technique [0002] As a widely distributed land cover type with important economic and ecological functions, grassland is one of the most important natural resources. Aboveground biomass of grasslands reflects grassland productivity, provides basic food sources for animal husbandry, and marks the health of grassland ecosystems. Therefore, accurate monitoring of grassland aboveground biomass and its temporal and spatial dynamic changes is of great significance for sustainable macro and precise grassland management, understanding the response of grassland to climate change, and protecting and restoring grassland ecosystems. [0003] On a fine scale, aboveground biomass in grasslands is mainly based on a certain sampling strategy, which is monitored by direct har...
