Detection system for degradation degree of high and cold mountain grassland based on remote sensing

Abstract

The invention discloses a system for detecting the degradation degree of an alpine mountain grassland based on remote sensing. The system comprises a detection device and an intelligent detection system, a sliding block slides up and down through work of a driving motor, so that a sealing plate is driven to slide inside and outside, the sealing plate slides inwards, the air pressure in an air box is increased, external air enters an electrical box through a filter screen, a component box is cooled firstly, and then the external air enters a connecting column and is blown to the driving motor; the sealing plate slides outwards, the sealing plate blows hot air in the air box into the interlayer through the exhaust pipe, the hot air is cooled to a certain degree due to the fact that the temperature of the protective cover is low, then the hot air is blown to the camera and finally exhausted through the exhaust hole, and the protective cover is made to be at a constant temperature; according to the system, effective heat dissipation of the system is achieved, effective demisting of the protective cover is achieved, the shooting definition is improved, and the service life of the system is prolonged.

Description

technical field [0001] The invention relates to the technical field of grassland degradation, in particular to a detection system for the degree of grassland degradation in alpine mountains based on remote sensing. Background technique [0002] Affected by natural conditions and human activities, the degradation of grassland biological resources, land resources, water resources and ecological environment, resulting in a decline in productivity is called grassland degradation. Grassland degradation will further reduce the ecological diversity of grasslands, significantly reduce the vegetation coverage of grasslands, increase the quantity of low-quality pastures, and intensify the process of desertification and desertification, forming a vicious circle and threatening the safety of the ecological environment. Monitoring the degree of grassland degradation is a prerequisite for grassland degradation prevention and protection of grassland ecological environment. [0003] In rec...
