The Occurrence and Progression of Pine Wilt Disease and Its Control Strategies in Shaanxi Province
摘要
Abstract
The pine forest area in Shaanxi Province covers 1.4307 million ha(89％concentrated in three cities in southern Shaanxi).Pine wilt disease(PWD)in Shaanxi caused by the invasive pine-wood nematode(Bursaphelenchus xylophilus)was first detected in Zhashui County,Shangluo City,in 2009.Its progression can be divided into three phases:2009-2017(Initial Stage):3-5 fluctuating infected areas;2018-2021(Expansion Stage):Infected areas increased to 25;2022-Present(Contain-ment Stage):By 2025,infected areas were reduced to 19,with no new reports in the province for four consecutive years and Xi'an remaining disease-free for four years.Significant control achievements have been made.By 2025,the number of infected areas decreased by 24％compared to 2021,and in-fection spots dropped by 36％.The number of dead pine trees declined from 283,500 in 2021 to 107,900 in 2023,a reduction of over 38％.A multi-dimensional control strategy has been implemented:Regarding policy,regulations were issued,establishing a"Province-City-County-Township"responsi-bility mechanism and a"Three Preventions and Two Clearances"approach.From technical perspec-tives,a"sky-ground integrated"monitoring system was developed,incorporating AI detection and rapid testing technologies.From the regional collaboration perspectives,a Cross-provincial joint pre-vention mechanisms and a Qinling Mountain control barrier were established.Regarding management,innovative mechanisms for infected wood disposal were promoted.From 2021 to 2023,central and provincial governments invested 362 million yuan and trained specialized teams.Current challenges in-elude technical bottlenecks in remote mountainous areas and insufficient interprovincial data sharing.Future efforts should focus on strengthening professional teams,advancing digital and intelligent con-trol,and striving to establish a"Shaanxi Model"for PWD management.关键词
