摘要 以外来疫病——油菜茎基溃疡病为例,提出一种未成功入侵外来生物导致的潜在损失评估方法,根据GARP生态位模型ArcGIS栅格数据图,通过掩膜工具Extract By Mask,提取出每个适生类型在中国各省份的分布面积。构建潜在损失估算模型,从潜在直接经济损失(农产品产值损失、农副食品加工业损失和防控费用)、潜在间接经济损失(油菜旅游产业)和潜在非经济损失(生态系统功能损失)3个方面构建外来入侵生物损失估算体系。研究发现油菜茎基溃疡病入侵的潜在损失总额高达96.05亿元,其中,潜在直接经济损失、潜在间接经济损失和潜在非经济损失分别占潜在损失总量的54.9%、36.0%和9.1%。动植物检疫在防范外来生物入侵中发挥着重要作用。 In this paper,an alien epidemic stalk-based ulcer disease of rapeseed was used as an example to propose an assessment methodology for the potential loss caused by an alien organism of unsuccessful invasion.According to the GARP niche model based on ArcGIS raster data map,the distribution areas of each adaptable variety in the provinces surveyed were extracted by the mask tool—Extract By Mask.The construction of an assessment model for the potential loss was attempted,that is,an assessment methodology for the potential loss caused by alien invasive organism was constructed from three aspects:potential direct economic loss(loss of agricultural output value,loss of agricultural and sideline food processing industry,prevention and control costs),potential indirect economic loss(rapeseed tourism industry)and potential non-economic loss(loss of ecosystem function).This research shows that the total potential loss of stalk-based ulcer disease of rapeseed was estimated at as high as 9.605 billion RMB,and the potential direct economic losses,potential indirect economic losses,and potential non-economic losses accounted for 54.9%,36.0%,and 9.1%of the total potential losses,respectively.This research concluded that animal and plant quarantine plays an important role in preventing the invasion of alien organisms.
