National Distribution Dataset of the Pine Wood Nematode (2016 -2024) in China

Since its introduction into China in 1982, the pine wood nematode, Bursaphelenchus xylophilus, has spread rapidly, posing an unprecedented threat to pine trees and about 70 species of conifers in China, and seriously threatening the security of forest resources and the balance of ecological environment in China. In view of the background of climate change and intensified human activities, the spread of the pine wilt disease (PWD) caused by this nematode is further accelerated, and the prevention and control situation is becoming increasingly serious. This dataset focuses on the distribution and spread of this globally devastating forest disease agent, the pine wood nematode, in China. The data came from the annual announcements of the PWD epidemic areas and their cancellation announcements released by the National Forestry and Grassland Administration. Using ArcGIS software, the attribute values of county-level administrative divisions were edited and processed based on the national 1:100,000 scale basic geographic information data. The annual distribution data set of the PWD epidemic area at county scale was generated to carry out thematic mapping of the PWD epidemic area. The data set covers the distribution of the PWD nationwide from 2016 to 2024, aiming to comprehensively reflect the spread trend and damage degree of the disease in different regions and different time periods through detailed geographic distribution information. The data set helps local authorities to identify epidemic risk points in time and provides early warning information for prevention and control efforts, and also helps to assess the impact of the epidemic on the natural landscape, ecological environment and economic and social development, and provides a basis for formulating targeted prevention and control measures.

自1982年传入中国以来，松材线虫（pine wood nematode，Bursaphelenchus xylophilus）快速扩散，对我国松树及约70种针叶树构成前所未有的威胁，严重危及我国森林资源安全与生态环境平衡。在气候变化与人类活动加剧的背景下，该线虫引发的松材线虫病（pine wilt disease, PWD）扩散进一步加速，防控形势日趋严峻。本数据集聚焦于这一全球毁灭性森林病原松材线虫在中国的分布与扩散情况。数据来源于国家林业和草原局（National Forestry and Grassland Administration）发布的松材线虫病疫区年度公告及疫区撤销公告。研究团队基于全国1:100,000比例尺基础地理信息数据，利用ArcGIS软件（ArcGIS）对县级行政区的属性值进行编辑与处理，生成县级尺度松材线虫病疫区年度分布数据集，用于松材线虫病疫区的专题制图。该数据集覆盖2016至2024年全国松材线虫病疫区分布情况，旨在通过精细化地理分布信息，全面反映该病在不同区域、不同时段的扩散趋势与危害程度。本数据集可助力地方主管部门及时识别疫情风险点，为防控工作提供预警信息；同时可用于评估疫情对自然景观、生态环境及经济社会发展的影响，为制定精准防控措施提供科学依据。
