摘要
为研究松材线虫病入侵对森林资源的影响,对比分析了九江市彭泽县、湖口县和都昌县3个老疫区2005年以来的历次二类森林资源调查数据,结果显示:疫区森林资源总量呈递增趋势,但资源呈现优势树种结构分化、林龄低龄化现象,马尾松林演替为混交林。为此,提出了对应的生态保护和防控建议。
In order to study the impact of Bursaphelenchus xylophilus invasion on forest resources,this study compared and analyzed the data of secondary forest resources in Pengze County,Hukou County and Duchang County of Jiujiang since 2005.The results indicated that the gross forest resources in the epidemic area mount up year by year,but the dominant seeds of trees were differentiated and the forest tendency of younger age,and the masson pine forest turn into the mingled forest.Therefore,the corresponding ecological prevention and control suggestions are put forward in this paper.
