Abstract:Abstract: In view of the lack of supervision technology and early warning ability of provincial management departments, this study explores the application practice of large-scale monitoring of abnormal discolored standing trees by using satellite remote sensing technology, so as to serve the technical guidance and supervision of regional pine wood nematode disease. After three years of application, it shows that high spatial resolution satellite remote sensing technology has the advantages of objectivity, science and quasi real time, and can become the “thousand mile eye and ear of the wind” of the superior managers.
