【摘要】 南松大小蠹Dendroctonus frontalis Zimmermann是美洲地区危害松杉类针叶树种的蛀干害虫。本文采用CLIMEX模型与ArcGIS分析相结合的预测方法,通过确定南松大小蠹的CLIMEX气候适应性参数,分析了南松大小蠹在我国的适生范围,并利用南松大小蠹的最低致死温度对适生范围进行限制。结果表明南松大小蠹在我国可能适宜其定殖的地区范围较广,其中在山东、河南、陕西、安徽中北部、山西南部、湖北中北部、四川部分地区和云南部分地区非常适合该小蠹的生存。更多还原

【Abstract】 Dendroctonus frontalis Zimmermann is one of the most economically important pests of Pinus plantations in America.Based on the biology of D.frontalis and climate data,potential suitable habitat for D.frontalis in China was predicted using CLIMEX and ArcGIS.The results show that D.frontalis has a wide potential distribution in China.Predicted optimum areas for establishment were most of north and southwestern China,including Shandong,Henan,Shanxi,Anhui,Shanxi,Hubei,Sichuan,Yunnan.更多还原
