摘要
采用描述性流行病学方法,对2020年全国松材线虫病疫情流行情况进行汇总分析,为科学制定全国松材线虫病疫情防控策略提供参考。结果表明:2020年全国共有18个省(区、市)726个县级行政区5479个乡镇级行政区发生松材线虫病疫情,疫情发生面积180.92万hm^(2),病死松树数量1947.03万株;疫情呈现聚集性分布,江西、广东、浙江、福建、安徽、重庆等省(市)有超过半数的疫区发生面积超过600 hm^(2);各疫区疫情危害差异较大,发生面积在>600~3600 hm^(2)的疫区疫情危害最严重;疫情监测能力不足,仅1成新发疫区发生面积不大于100 hm^(2)。扭转松材线虫病疫情快速扩散蔓延态势迫在眉睫。
Epidemic situation of pine wilt disease in China in 2020 was analyzed by descriptive statistical analysis.The results showed that the disease had occurrence area of 1.8 millions hm^(2) with dead pine trees of 19.4703 million,which distributed in 5479 township administrative areas,726 counties,18 provinces,and appeared in an aggregated distribution.More than half of the epidemic areas in such provinces as Jiangxi,Guangdong,Zhejiang,Fujian,Anhui,Chongqing had occurrence area of more than 600 hm^(2),with significant differences in damage.The epidemic situation in epidemic areas between 600 and 3600 hm^(2) were more serious.The epidemic surveillance capability was insufficient,only 10%of the new epidemic areas were not more than 100 hm^(2).Strengthening the epidemic monitor and reducing its spreading speed has became an extremely urgent matter at present.
