摘要
本研究采用文献调研、实地考察与专家咨询相结合的方式,调查了湖南省农林业生态系统中外来有害生物的种类及分类地位、起源、引入路径和危害影响等内容。查明我省共有农业外来有害生物233种,包括植物183种,动物26种,病原微生物24种;这些农业外来有害生物中,来自美洲的有142种,占总数的60.9%,来自亚洲的有38种,占总数的16.3%,来源于欧洲的28种,占总数的12.0%,来源于非洲的有17种,占总数的7.3%,来自大洋洲的有7种,占总数的3.0%,1种外来有害生物尚不清楚其来源。外来物种主要通过人为因素先传入我国,而后进一步扩散至湖南,因此我们既要加强省内各入境口岸的检疫工作,又要对人为引种进行严格的风险评估和后续管理工作。
Based on literature research,field survey and consultation,233 alien pests had been identified in Hunan Province,including 183 weeds,26 insects and mollusk and 24 pathogenic microorganism. Among these alien pests,142 were from America,accounting for 60.9%,38 were from Asia, 16.3% of the total,28 were from Europe,accounting for 12.0%,17 were from Africa,accounting for 7.3%,and 7 were from Oceania,accounting for 3.0%, 1 species origination was not yet known. All of most alien pests were intentionally or unintentionally introduced to China through human activities and then spreaded to Hunan. Therefore,we need to strengthen the port inspection and quarantine work and conduct strict risk assessment and subsequent management on exotic species.
