中文摘要:
【目的】 南部松齿小蠹Ips grandicollis (Eichhoff)是我国重点关注的检疫性林木害虫且在我国内尚无分布。近年来,随着进口木材数量的增长,该虫传入我国的风险加大。因此,充分了解该虫的适生区有助于我国针对性地开展其检疫防控工作。【方法】 本文采用气候相似性分析法,利用SPSS及DIV-GIS等软件对南部松齿小蠹的适生区进行分析,其中利用SPSS软件分析了19个可影响南部松齿小蠹适生性的生物气候变量,筛选出6个关键气候变量;然后,通过DIV-GIS工具,对这6个关键气候变量进行了计算分析,得出了南部松齿小蠹适生区预测结果。【结果】南部松齿小蠹在全球的高度适生区主要集中在北美洲的中东部,南美洲的中东部,欧洲的中东部,非洲的中南部及东部沿海地区,亚洲的中部及东部沿海以及澳大利亚的沿海地区;而在我国的境内高度适生区主要在山东、江苏的东部沿海、河南、湖北、重庆等诸多中、南部地区。最后,本文对所用分析法及预测结果进行了讨论,并提出了检疫防控的措施建议。【结论】 南部松齿小蠹寄主木材的进口口岸均在本文预测的适生区范围内,因此值得提请相关部门关注,应加强其检疫及监测措施。
英文摘要:
[Objectives] Although it has yet to establish in China, Ips grandicollis is one of the country’s most important quarantine forest pests. In recent years, the risk of it establishing has risen due to the increased amount of imported timber. Predicting potentially suitable habitat for this species is therefore timely as this will allow quarantine, prevention, and control, operations to be targeted more efficiently if required. [Methods] Climate similarity analysis methods using DIV-GIS and SPSS software tools were used to predict suitable I. grandicollis habitat in China. Nineteen bioclimatic variables that could influence the establishment of I. grandicollis were first analyzed with SPSS and six key variables identified. DIV-GIS was then used to analyze these key variables and predict suitable I. grandicollis habitat. [Results] Globally, the most suitable I. grandicollis habitat is mainly in mid-eastern North America, mid-eastern South America, mid-eastern Europe, the mid-south and eastern coastal areas of Africa, central and eastern coastal areas of Asia, and coastal regions of Australia. In China, the most suitable habitat is mainly in the mid-south of Shandong, Henan, Hubei and Chongqing. Analytical method and predicted results are discussed and advice given for the quarantine, prevention and control of I. grandicollis. [Conclusion] Relevant departments should reinforce quarantine and monitoring measures for I. grandicollis because the ports importing the wood of host trees of this species are all located in regions with predicted suitable habitat.
