Mangrove forest ecological quantitative inversion method based on remote sensing technology

Abstract

The invention belongs to the technical field of remote sensing ecological quantitative inversion, and discloses a mangrove forest ecological quantitative inversion method based on a remote sensing technology. The method comprises the following steps: shooting a hyperspectral remote sensing image of an area containing a mangrove forest by using aviation acquisition equipment; extracting mangrove forest information from the processed hyperspectral data; carrying out reflection peak wave band interception on the mangrove forest information; judging the intercepted reflection wave band, and performing mangrove forest identification based on a judgment result to obtain a mangrove forest inversion result. According to the method, the ecological quantitative inversion of the mangrove forest is realized by using the hyperspectral remote sensing data, the method is rapid and convenient, no influence is caused on vegetation growth, and the precision is high. The inversion precision of mangrove forest can be improved, and the wrong extraction or missing extraction of mangrove forest probability is reduced; the method has important popularization and application values in the aspects of mangrove forest growth monitoring, forest mapping, biomass estimation, mangrove forest disease and insect pest monitoring, early warning and forecasting and the like.

Description

Technical field [0001] The present invention belongs to the field of remote sensing ecological quantitative inversion techniques, and more particularly to a mangrove, an ecological quantitative inversion method based on remote sensing techniques. Background technique [0002] Current: Mangrove is growing in tropical, subtropical coastal tide band, evergreen wood plant communities composed of red trees or shrubs made from mangrove plants, in purification of seawater, wind-resistant surf, carbon storage, maintenance of organisms Diversity and other aspects play an important role, there is a reputation of "Coast Guard", "Ocean Green Lung", is also an important habitat, fish, shrimp, crab and shellfish growth breeding. China's red tree plant is distributed in Guangdong, Guangxi, Hainan, Fujian, Zhejiang and other provinces. However, there is no determination method for the ecological quantitative inversion method for mangroves. In the existing invention, there is no method for the ec...
