Embodiment Construction

[0025] 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 examples cited are not intended to limit the present invention.

[0026] A satellite remote sensing monitoring method for the chlorophyll a content of the jujube tree canopy specifically includes the following steps:

[0027] 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 transits, download the remote sensing image of the Landsat8 satellite in the area to be monitored. The specific implementation time of this embodiment is August 9, 2016, and the area to be monitored is the Jujube Base of Bashan Company in the 11th Regiment of Xinjiang First Division, and the sky is clear and cloudless that day. In ...

Abstract

The invention provides a satellite remote sensing monitoring method for jujube canopy chlorophyll a content, comprising the following steps: determining the area to be monitored; downloading the satellite remote sensing image of the area to be monitored; performing geometric precision correction and radiation correction on the downloaded satellite remote sensing image in sequence , Atmospheric correction; crop the satellite remote sensing image after atmospheric correction to obtain the monitoring area image; use ENVI5.1 software to calculate the 5 vegetation indices of the selected pixels in the monitoring area; substitute the 5 vegetation indices into the model through band operation, and calculate The chlorophyll-a content of jujube canopy in each pixel; where, Y is the chlorophyll-a content of jujube canopy in mg / g. The method provided by the invention realizes rapid, accurate, economical and environmentally friendly acquisition of jujube canopy chlorophyll a content data on a regional scale, avoids environmental pollution and human body damage caused by chemical tail liquid discharge during the measurement process, and greatly simplifies the operation steps , to shorten the monitoring time.

Description

Technical field [0001] The invention belongs to the technical field of satellite remote sensing monitoring, and particularly relates to a satellite remote sensing monitoring method for the chlorophyll a content of the jujube tree canopy. Background technique [0002] Chlorophyll is the main pigment in plants and the most important pigment. Higher plant chlorophyll consists of two types, chlorophyll a and chlorophyll b. They participate in the absorption, transmission and transformation of light energy, and control the amount of solar radiation absorbed by the leaves, thereby controlling photosynthesis. Potential and primary productivity. The chlorophyll content can also be used to accurately and indirectly estimate the nutritional status of plants. The change of chlorophyll is an indicator of environmental stress and phenological phase. When plants are under stress and in the process of senescence, the content of chlorophyll will decrease, and the wallpaper of chlorophyll a and ...
