Embodiment Construction

[0024] In order to enable those skilled in the art to better understand that the technical solutions of the present invention can be implemented, the present invention will be further described below in conjunction with specific examples, but the given examples are not intended to limit the present invention.

[0025] A method for satellite remote sensing monitoring of jujube canopy carotenoid content, specifically comprising the following steps:

[0026] Query the transit time of the Landsat8 satellite in the area to be monitored. The resolution of the Landsat8 satellite is 30 meters. If the weather is clear and cloudless when the satellite passes, download the remote sensing image of the Landsat8 satellite in the area to be monitored that day. The specific implementation time of this embodiment is on August 9, 2016. The area to be monitored is the red date base of Bashan Company in the 11th regiment of Xinjiang First Division. The sky was clear and cloudless that day. In thi...

Abstract

The invention provides a satellite remote sensing monitoring method for the content of jujube tree canopy carotenoid. The method comprises the following steps of determining a region to be monitored; downloading a satellite remote sensing image of the region to be monitored; sequentially performing geometric precise correction, radiation correction and atmospheric correction on the downloaded satellite remote sensing image; cutting the satellite remote sensing image obtained after atmospheric correction and obtaining an image of the monitored region; calculating the monitored region through ENVI5.1 software for selecting seven vegetation indexes of pixels; substituting the seven vegetation indexes into a model through wave band calculation, and working out the content of the jujube tree canopy carotenoid of each pixel, wherein Y is the content of the jujube tree canopy carotenoid, and the unit is mg / g. According to the method, the content data of the jujube tree canopy carotenoid is rapidly and accurately obtained in the regional scale in an economical and environment-friendly mode, environmental pollution and human injuries caused by chemical tail liquid discharge in the determination process are avoided, the operation steps are greatly simplified, and the monitoring time is shortened.

Description

technical field [0001] The invention belongs to the technical field of satellite remote sensing monitoring, and in particular relates to a satellite remote sensing monitoring method for carotenoid content in jujube canopy. Background technique [0002] Carotenoids are the second largest class of main pigments in plant pigments. They are red, orange or yellow tetraterpenoids, which are composed of carotene and lutein; carotenoids can also absorb solar radiation and transfer energy to Contributed to photosynthesis, it is a component of the complex of antenna pigments and reaction center pigments. When the radiation energy exceeds the needs of photosynthesis, the carotenoid component lutein cycle will dissipate excess energy, thereby protecting the reaction center. The heat dissipation that depends on the lutein cycle is a key energy dissipation mechanism in higher plants. Lutein is closely related to the light energy utilization rate of photosynthesis. Therefore, the concentra...
