摘要
为进一步开展欧洲输华粮谷中有害生物风险分析,该文整理和统计2003—2017年我国自欧洲输华粮谷中截获的有害生物数据,并采用SPSS 20软件分别对所截获的主要杂草和昆虫进行了聚类分析、相关分析和主成分分析,确定其截获次数的主控因子。结果显示,我国自欧洲输华粮谷中截获的主要有害生物为杂草,截获记录数为7905次,占总截获记录的79.99%;我国自欧洲输华大麦中截获的有害生物次数均最多,截获次数为57843次,占总截获次数的51.39%;我国自乌克兰输华粮谷中截获的杂草和昆虫次数最多,分别为39026次和678次;我国自欧洲输华粮谷中截获的杂草和昆虫分别为479种和61种;自乌克兰和大麦中截获的杂草和昆虫的Shannon-Weiner指数均相对较高;我国自欧洲输华大麦和玉米中截获的杂草和昆虫分别单独聚为一类,我国自乌克兰和法国输华粮谷中截获的杂草和昆虫分别单独聚为一类;欧洲输华粮谷贸易额是有害生物杂草和昆虫截获次数的主控因子。建议我国进一步做好有害生物截获数据收集工作,加强欧洲输华粮谷中有害生物风险分析,根据风险对不同国家和粮谷采取相应的检疫措施。
In order to further carry out pest risk analysis of European grains exported to China,this study collected the data intercepted from European grains exported to China from 2003 to 2017,used SPSS 20 software to carry out cluster analysis,correlation analysis and principal component analysis on the intercepted main pest weeds and insects,and determined the main factors controlling their interception times.The results showed that weeds were the main pests intercepted in grains exported from Europe,and the number of intercepted records was 7905,accounting for 79.99%of the total intercepted records;the number of pests intercepted from barley exported to China from Europe was the highest(57843 interceptions),accounting for 51.39%of the total interceptions;the numbers of weeds and insects intercepted from the grains exported to China from Ukraine were the highest(39026 and 678 respectively);there were 479 species of weeds and 61 species of insects intercepted from grains exported to China from Europe;the Shannon-Weiner indexes of weeds and insects intercepted from Ukraine and barley were relatively high;the weeds and insects intercepted from barley and corn exported to China from Europe were grouped into one category separately,and the weeds and insects intercepted from grains exported to China from Ukraine and France were grouped into one category separately.The trade volume of European grains exported to China was the main factor controlling the interception times of weeds and insects.It suggested that China should improve the collection of pest interception data,strengthen the pest risk analysis of European grains exported to China,and take appropriate quarantine measures for different countries and grains according to their risks.
