Problems solved by technology

[0003] At present, the method of determining the amount of grass yield and its corresponding grazing rate in the alpine meadow is mainly to select representative sampling points in the field to arrange quadrat sampling, and then use the representativeness of the quadrat to estimate the grass yield in the area. The method of obtaining the grass yield and then obtaining the grazing rate is time-consuming and labor-intensive, and there are large errors

Abstract

The invention relates to the field of environmental protection and particularly discloses a method and system for estimating the grazing rate based on the grass yield of alpine meadow grassland. The method comprises the following steps of acquiring a grassland coverage area image set based on a real-time remote sensing image of alpine meadow grassland and a Faster R-CNN model constructed by adopting a grassland image set in historical alpine meadow grassland; calculating the area of a grassland coverage area; achieving rapid estimation of the grass yield of the alpine meadow grass land by combining the length parameters of the grass corresponding to the grass in the time period; then, estimating the corresponding grazing rate according to the estimated grass yield of the alpine meadow grass land based on a grazing rate conversion model, so that the grazing rate corresponding to the current grassland can be quickly and accurately obtained, and the situation of grassland degradation caused by excessive grazing is avoided.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a method and a system for estimating grazing rate based on grass yield of alpine meadow. Background technique [0002] The alpine meadow ecosystem is the main grassland ecosystem type on the Qinghai-Tibet Plateau, and the animal husbandry on the alpine meadow is the leading industry in the Qinghai-Tibet Plateau. At present, due to the unreasonable development and utilization of local herdsmen, such as overloading and overgrazing, the alpine meadow grassland in this area has been seriously degraded, and the determination of the grass yield and the corresponding grazing rate of the cold meadow meadow is the most effective way to avoid the alpine meadow. Methods of Meadow Grass Degradation. [0003] At present, the method of determining the amount of grass yield and its corresponding grazing rate in the alpine meadow is mainly to select representative sampling points in th...
