摘　　要：结合动、植物引种的研究问题,采用二元比较级方法确定了模糊相似比矩阵(?),分别用λ-截矩阵和下确界两种方法,获得了论域各对象关于生态因子相似度的优劣排序决策.In light of introducing new breed of animals and plants, fuzzy matrix R of ratio of similitude is affirmed by the binary means of comparative degree. By means of X-matrix to be cut out and infimum, the decision-making that made by the order of superior and inferior of ecology factors similar degree.
