摘　　要：利用模糊数学综合评价原理和层次分析法,建立了一套参考生物选择的数学处理流程。以关心度为选择指标,通过建立预选种群、确定选择指标、确定指标权重,并对指标进行量化和模糊计算得到了指标的模糊关系矩阵,最后计算得到了预选种群的关心度,实现了多种准则下的综合评价。以EPIC(environmental protection from ionizing contaminants in the arctic)为例计算了16种生物种群的关心度,发现了包括以浮游植物为食的哺乳动物在内的生物种群更加适合于做参考生物。A fuzzy comprehensive evaluation and analytic hierarchy were used to develop a mathematical procedure for selecting reference organisms where the concern degree is used as the selection index.The fuzzy relationship matrix for the index was determined by analyzing selected species to determine index weights and values in fuzzy calculations.The concern degrees for each selected species were then evaluated for multiple criteria.The model was used in an environmental study of ionizing contaminants in the arctic（EPIC） to calculate the concern degrees of 16 species.The results show that several species including planktotrophic mammals can be selected as reference organisms.
