Sky-ground integrated pine wood nematode disease epidemic situation remote sensing monitoring method

Abstract

The invention relates to a sky-ground integrated pine wood nematode disease epidemic situation remote sensing monitoring method, which comprises the following steps of: acquiring multi-source monitoring original data aiming at a pine wood nematode disease epidemic situation by adopting a method of integrating satellite remote sensing images, satellite remote sensing images and ground treading, and pre-processing an obtained pine wood nematode disease epidemic situation area data set to obtain a remote sensing interpretation sample aiming at a pine wood nematode disease epidemic situation area, and performing processing according to an acquired pine wood nematode disease epidemic situation area data set and the remote sensing interpretation sample to acquire a pine wood nematode disease epidemic situation monitoring result aiming at the pine wood nematode disease epidemic situation area, so that the defect of a single monitoring data source is overcome; according to the invention, comprehensive monitoring of the pine wood nematode disease epidemic situation area is realized, the monitoring accuracy and the monitoring efficiency are improved, withered and dead trees caused by pine wood nematode diseases can be found more comprehensively, quickly and accurately, and detailed data guarantee is provided for subsequent formulation of prevention and treatment schemes.

Description

technical field [0001] The invention relates to the field of remote sensing monitoring, in particular to an air-ground integrated remote sensing monitoring method for pine wood nematode epidemic situation. Background technique [0002] Pine wood nematode disease, also known as pine blight, is one of the most harmful diseases in forest ecosystems in the world. The disease has the characteristics of wide transmission route, fast speed and difficult prevention and control, so it is called "the cancer of pine trees". Pine wood nematode disease will not only cause serious economic losses, but also endanger the development of forest resources and the stability of ecological environment. Epidemic monitoring and investigation is the basis for the prevention and control of pine wood nematode disease. Accurate and efficient monitoring of pine wood nematode disease epidemic is of great significance for comprehensively grasping the epidemic information and timely curbing the spread of ...
