在分析影响种苗引种风险的基础上,使用专家评估法,研究筛选了国外引种风险评价指标,分析并确定了各指标权重、评判标准及评判等级。针对各指标间的内在逻辑关系,利用适当的数学关系,确定了国外引种风险评价数学模型,从而构建形成了国外引种风险评价指标体系,为我国从国外引种的检疫风险分析提供了科学依据。
Based on the analysis of the risk of introduction of seedlings, the expert evaluation method was used to study and select the risk evaluation index of foreign introduction, and the weight, criteria and grade of each index were analyzed and determined. According to the internal logic of each index, using the appropriate mathematical relationship, the mathematic model of foreign introduction risk assessment was established, which established the index system of foreign introduction risk assessment and provided a scientific basis for the quarantine risk analysis of foreign introduction in our country.
