Method for detecting landform of mangrove forest based on Landsat satellite remote sensing

Abstract

The invention discloses a method for detecting the landform of a mangrove forest based on Landsat satellite remote sensing, which is characterized in that a plurality of effective feature extraction means and an end-to-end training method are adopted, an obtained model has an end-to-end mangrove forest identification prediction function, and the method specifically comprises the following steps of data acquisition and expansion, network design, network training and output and the like. Compared with the prior art, the method has the advantages that the size of the input Landsat satellite remote sensing data is not limited, the growth condition and dynamic condition of mangrove forest vegetation can be accurately monitored, the identification efficiency and precision are high, the method is simple and convenient, and the effectiveness is high.

Description

technical field [0001] The invention relates to the technical field of satellite remote sensing and computer vision, in particular to a method for detecting mangrove landforms based on Landsat satellite remote sensing. Background technique [0002] Mangroves are wetland woody plant communities that grow in the intertidal zone of tropical and subtropical coasts and are composed of evergreen trees or shrubs mainly composed of mangroves. It has the reputation of "Coast Guard" and "Ocean Green Lung". It is also an important habitat for rare and endangered waterfowl, and a breeding ground for fish, shrimp, crab, and shellfish. It is reported that 35% of the mangrove forests in the world have disappeared, and it is still decreasing at a rate of 1-2% per year. In order to better protect the mangrove ecosystem, accurately grasp the growth and dynamics of mangrove vegetation, and monitor mangrove species The spatial distribution is very necessary. However, the density of species in...

Problems solved by technology

[0004] The purpose of the present invention is to propose a method for detecting mangrove landforms based on Landsat satellite remote sensing in view of the deficiencies in the prior art. It adopts a variety of effective feature extraction methods and end-to-end training methods, and the obtained model has end-to-end redness. For forest identification and prediction, there is no limit to the size of the input Landsat satellite remote sensing data, which not only reduces the time and energy invested, but also has good performance, and can accurately monitor the growth
