摘要
通过对曹妃甸口岸2010—2014年进口矿砂中监测到的杂草进行统计与分析,初步确定曹妃甸口岸新发现杂草有17科35属41种,外来杂草23种。对外来杂草原产地分布进行初步分析,结果表明,进口矿砂中传带的杂草种类繁多,检疫性杂草入侵风险较大,建议加强对进口矿砂的检疫和后续监管,防止外来有害杂草在口岸辖区内定殖扩散,造成危害。
Based on the data statistics and analyses of weed seed monitored in ore sand at Caofeidian ports in 2010—2014,42 weed species belonging to 17 families and 35 generas were found,among which 24 species cosidered invasive were preliminarily studied to determine their origin. Weed species in imported ore sand were numerous and posed a major invasion risk from species of quarantine importance. Therefore it is suggested to strengthen the quarantine measures to imported ore sand and follow- up supervision to prevent invasive weeds from spreading and causing harm.
