Grassland satellite remote sensing monitoring system and method

Abstract

The invention discloses a grassland satellite remote sensing monitoring system and a grassland satellite remote sensing monitoring method. The system comprises a grassland growth potential monitoring module, a grassland grass yield monitoring module and a grass-livestock balance monitoring module, wherein the grassland growth potential monitoring module is used for acquiring a grassland normalized difference vegetation index (NDVI) and a grassland growth index (GI) by processing data of a satellite remote sensing moderate resolution imaging spectrometer (MODIS) in different periods according to the relation between remote sensing information and the condition of grassland vegetation on the ground to reflect the growth potential of the grassland vegetation; the grassland grass yield monitoring module is used for establishing a grass yield estimating model by combining yield measuring data of ground quadrats according to the information of the satellite remote sensing MODIS and inverting the grass yield of grasslands according to the data of the remote sensing MODIS; and the grass-livestock balance monitoring module is used for estimating the grass-livestock balance condition by combining the current grass yield, foraged grass yield and replenished forage grass of natural grasslands according to the grass yield acquired by the grassland grass yield monitoring module.

Description

technical field [0001] The invention relates to grassland monitoring technology, in particular to a grassland satellite remote sensing monitoring system and method based on MODIS (Moderate Resolution Imaging Spectrometer) data. Background technique [0002] Grassland vegetation remote sensing monitoring is the use of 3S technology (remote sensing, geographic information system and global positioning system), combined with ground survey data to realize the monitoring of grassland vegetation. The content of remote sensing monitoring of grassland vegetation mainly includes the growth of grassland vegetation, the biomass of grassland vegetation and the estimation of the balance of grassland and livestock. With the continuous development and maturity of 3S technology, especially the rapid development of earth observation technology, the continuous improvement of high temporal and spatial resolution satellite remote sensing data acquisition technology, and the rapid development of...
