摘要
在全面调查保定市清苑区外来入侵植物现状的基础上,本研究对清苑区外来入侵植物进行风险评估,为进一步开展全国外来物种调查评估提供基础数据和评估方法支撑。研究采用清查、踏查、访问调查、样地调查等方法调查了保定市清苑区不同区域外来入侵植物种类、空间分布、盖度、面积、危害程度、社会经济影响和生态损失,运用层次分析法(AHP)对入侵植物的传入风险、生物学特征、扩散特征、已入侵现状、危害和影响、防除难度进行综合评估,评估其危害和风险等级。调查发现,保定市清苑区外来入侵植物共33种,隶属于13科24属。数量最多的为菊科,共9种,占总种数的27.27%,其次为苋科,共5种,占15.15%。入侵植物中有意引入的有20种,占60.61%;无意引入的有10种,占30.30%;自然扩散的有3种,占9.09%。入侵植物中草本植物有30种,占90.91%;原产地为美洲的19种,占57.58%;产自欧洲的有10种,占30.30%。清苑区北店乡是发现入侵植物种数最多的乡镇,共发现22种。风险评估结果表明,保定市清苑区Ⅰ级外来入侵植物有2种,Ⅱ级植物3种,Ⅲ级植物2种,Ⅳ级植物8种,Ⅴ级植物18种,其中危害程度最大的入侵植物是大狼杷草和黄顶菊。研究表明,保定市清苑区入侵物种数量不多,风险等级高的入侵植物较少,建议对黄顶菊等恶性入侵植物加强监测。
Based on a comprehensive investigation of invasive alien plants in Qingyuan District,Baoding City,this study conducted a risk assessment of the invasive alien plants in Qingyuan District,and provided basic data and evaluation methods for further investigation and evaluation of alien species across the country.The species,spatial distribution,coverage,area,degree of damage,and socio-economic and ecological loss of invasive alien plants in different areas of Qingyuan District of Baoding City were investigated through inventory,step-bystep surveys,interview surveys,and sample plot surveys.The introduction risk,biological characteristics,spread characteristics,status of invasion,harm and impact,and control difficulty of invasive plants were comprehensively assessed,along with their hazard and risk levels.The survey found 33 species of invasive plants in Qingyuan District,Baoding City,belonging to 13 families and 24 genera.Compositae had the largest number,with nine species,accounting for 27.27%of the total species.This was followed by five species of Amaranthaceae accounting for 15.15%of invasive species.Twenty species were introduced intentionally,accounting for 60.61%;ten species were introduced unintentionally,accounting for 30.30%;and three species were naturally diffused,accounting for 9.09%.Of the invasive species,there were 30 herbs,accounting for 90.91%of invasive species.The origin of 19 species was from America,accounting for 57.58%,followed by 10 species from Europe,accounting for 30.30%.Beidian Township of Qingyuan District had the largest number of invasive plant species,with 22 species.The results of the risk assessment showed that there were two species of classⅠinvasive alien plants,three species of classⅡplants,and two species of classⅢplants in Qingyuan District,Baoding City.Additionally,there were 8 gradeⅣplants and 18 gradeⅤplants.The most harmful of these invasive plants on the risk assessment scale are Bidens frondosa and Flaveria bidentis.While the number of invasive species in the Qingyuan District of Baoding is not high,there are a few invasive plants with high-risk levels.Therefore,it is recommended to strengthen the monitoring of those invasive plants.
