Dynamic remote-sensing forage and livestock monitoring and grazing early-warning method

Abstract

The invention provides a dynamic remote-sensing forage and livestock monitoring and grazing early-warning method, and belongs to the fields of dynamic remote sensing meadow monitoring and grazing early warning. The method comprises that nutrition indexes including biomass, crude protein, neutral washing fibers, acidic washing fibers and stock-carrying capacity reflecting the nutrition value of meadows are calculated by means of multi-source remote-sensing sequential images; and the livestock grazing route, nutrition demand and stock-carrying capacity are calculated via a livestock grazing system and nutrition supplementary feed, the meadow nutrition supply and livestock nutrition demand are analyzed, the herbage nutrition change process of a rotation grazing district is monitored quantitatively, the dynamic nutrition balance is analyzed, and early warning is implemented. The method is suitable for high-score remote-sensing vegetation index data. Indexes of different links of remote-sensing dynamic meadow nutrition monitoring are researched quantitatively, so that forage and livestock nutrition balance and grazing monitoring early warning can be researched qualitatively, it is ensured that the meadow nutrition change and dynamic forage and livestock nutrition balance of a divided pasture can be reflected in higher precision, and more accurate information is provided for a nutrition balancing decision.

Description

technical field [0001] The invention relates to the technical field of grassland remote sensing dynamic monitoring and grazing early warning, in particular to a grass livestock dynamic remote sensing monitoring and grazing early warning method. Background technique [0002] Rational use of natural grassland is an important direction for the development of grassland animal husbandry, and "ecology, greenness, and health" are important symbols for the development of grassland animal husbandry. "How to protect the ecological environment while developing grassland animal husbandry is a major issue facing the ecological construction of Qinghai Province and other pastoral areas." The relationship between ecological environment protection and grassland animal husbandry in this area undoubtedly has many contradictions and problems between "protection and development, promotion and regulation, promotion and restriction". Optimizing the production mode of forage livestock is an effect...

Problems solved by technology

[0005] At present, domestic and foreign studies on grassland remote sensing dynamic monitoring and grazing early warning mainly analyze grassland information acquisition, national and provincial grassland-livestock balance, grassland nutritional parameter inversion and grassland degradation monitoring, etc. Monitoring and grazing early warning methods, the research in this area is still very limited, and cannot be comprehensive, in-depth, and quantitatively serving the research on efficient grazing technology support
