Embodiment Construction

[0022] 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.

[0023] A satellite remote sensing monitoring method of jujube canopy chlorophyll b content, specifically comprising the following steps:

[0024] 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 this...

Abstract

The invention provides a satellite remote sensing monitoring method for the jujube tree canopy chlorophyll b content. The method comprises the following steps that a to-be-monitored area is determined; a satellite remote sensing image of the to-be-monitored area is downloaded; geometric precision correction, radiation correction and atmospheric correction are sequentially conducted on the downloaded satellite remote sensing image; the satellite remote sensing image obtained after atmospheric correction is cropped to obtain a monitored area image; five vegetation indexes of each pixel selected from the monitored area are calculated through ENVI5.1 software; the five vegetation indexes are substituted into a model through waveband calculation, and the jujube tree canopy carotenoid content of each pixel is calculated, wherein Y is the jujube tree canopy chlorophyll b content, and the unit of the jujube tree canopy chlorophyll b content is mg/g. According to the method, the jujube tree canopy chlorophyll b content data is quickly and accurately acquired in an economical and environment-friendly mode on regional scale, pollution to the environment and harm to human bodies of chemical tail liquid discharge in the measurement 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 the content of chlorophyll b in jujube canopy. Background technique [0002] Chlorophyll is the main pigment in plants and the most important pigment. There are two types of chlorophyll in higher plants, chlorophyll a and chlorophyll b. They participate in the absorption, transmission and conversion of light energy, and control the amount of solar radiation absorbed by leaves, thereby controlling photosynthesis. potential and primary productivity. Chlorophyll content can also be used to accurately and indirectly estimate plant nutritional status. The change of chlorophyll is an indicator of environmental stress and phenological period. When the plant is under stress and in the aging process, the content of chlorophyll will decrease, and the wallpaper of chlorophyll a and chlorophyll b will a...
