Abstract

The embodiments of the invention disclose a method and apparatus for monitoring grassland biomass by remote sensing. The method includes obtaining a grassland type spatial distribution vector map, a climate vector map, an elevation vector map, an administrative division vector map, a sample data vector map and a vegetation index vector map in a target area; in ArcGIS software, the vector maps being superposed and analyzed as different layers, and then the target area being divided into several regions which are suitable for different biomass estimation models. Before monitoring grassland biomass by remote sensing, a GIS spatial analysis method is used to divide that target area into a plurality of partitions, so that different biomass estimation models can be used for different regions inremote sensing monitoring, which makes the biomass monitoring in the target area more accurate and more suitable for high-precision monitoring of grassland biomass under large-scale and complex conditions.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of remote sensing monitoring, and more specifically, to a method and device for remote sensing monitoring of grassland biomass. Background technique [0002] Grassland biomass is the material basis for maintaining grassland ecosystems and an important indicator for diagnosing the health of grasslands. Grassland biomass monitoring is an important basis for the rational utilization of grassland resources and the monitoring of livestock balance. With the development of modern remote sensing technology and the increase in the number of remote sensing satellites, the use of remote sensing methods to monitor grassland biomass has become an important technical means. [0003] my country's natural grasslands have 18 types of grasslands, accounting for about 41.7% of the total land area. Natural conditions such as landforms and climate in grassland areas are complex, coupled with the influe...
