Abstract

The invention discloses a forest environment monitoring method and system based on multispectral remote sensing. The method comprises the steps of: acquiring first historical environment features of a first forest region; according to the first historical environment features, performing region division on a first forest region from a first dimension and a second dimension; acquiring multispectral remote sensing data of each region, and constructing a first remote sensing data set; performing data dimension reduction processing on the first remote sensing data set to obtain a second remote sensing data set; acquiring first ground feature parameters of the first forest region; and combining the second remote sensing data set with the first ground feature parameters to obtain first environment monitoring information of the first forest region. The technical problem that in the prior art, in the monitoring process of the forest environment based on the multispectral remote sensing technology, the hierarchy of monitoring data is poor, and consequently the monitoring result is not ideal enough is solved.

Description

technical field [0001] The invention relates to the field of multispectral remote sensing, in particular to a forest environment monitoring method and system based on multispectral remote sensing. Background technique [0002] Multi-spectral resolution remote sensing is a remote sensing technology that uses sensors with more than two spectral channels to simultaneously image ground objects. It divides the electromagnetic wave information reflected by objects into several spectral segments for reception and recording. Remote sensing technology is widely used in forestry, mainly including the following aspects: remote sensing survey of forest resources, remote sensing monitoring of forest fires, remote sensing monitoring of forest diseases and insect pests, and remote sensing dynamic monitoring of forest resources. Through remote sensing technology, remote sensing investigation of forest resources and remote sensing monitoring of forest fires can be realized. [0003] In the ...
