T/AOPA 0052-2023 Drone monitoring technical specifications for dead pine trees infected with pine wood nematode disease

Scope

Main technical content: Pine wood nematode disease is one of the most destructive forest diseases in the forest ecosystem and is often referred to as the "cancer" of pine trees. Since its first occurrence in Nanjing, Jiangsu in 1982, the epidemic has continued to spread, making pine wood nematode disease one of the most serious and dangerous major forestry diseases in China in recent decades. According to the announcement of the National Forestry and Grassland Administration (No. 6 of 2022), as of 2022, pine wood nematode disease has spread to 731 county-level administrative regions in 19 provinces (regions and cities), with an affected area of over 1.8 million hectares, killing billions of pine trees and causing incalculable direct and indirect economic losses. Currently, more than 90% of healthy pine forests are facing the threat of pine wood nematode disease transmission and infection. Epidemic monitoring of pine wood nematode disease is the prerequisite for all prevention and control efforts. With the advancement of drone technology, the miniaturization of multispectral and hyperspectral information collection equipment, and the continuous improvement of remote sensing image analysis algorithms, drone remote sensing monitoring technology is gradually gaining popularity due to its economic and efficient advantages. More and more forestry-related departments are adopting drone remote sensing measurement technology to monitor the epidemic of pine wood nematode disease. However, the related equipment and technologies currently available on the market are uneven and lack unified technical standards, which seriously affects the quality of monitoring results. Therefore, in order to promote the healthy development of the industry, it is essential to establish a systematic set of norms for drone monitoring technology of pine wood nematode-killed trees.
