摘　　要：试验探究了外来物种琵琶鼠鱼(Pterygoplichthys multiradiatus)和本地物种鲫鱼(Crucian carp)混养时的关系,研究入侵物种对生物多样性和生态环境的破坏。结果表明,琵琶鼠鱼与鲫鱼在不同配比的混养情况下,体重均表现为降低,其中琵琶鼠鱼的体重下降更多,但均有正增长的趋势。琵琶鼠鱼与鲫鱼之间存在空间竞争关系,且鲫鱼表现出更强的竞争优势。In order to study the biological diversity and ecological environment distruction from exotic species, this experiment was conducted to explore the relationship between the exotic species Pterygoplichthys multiradiatus and indigenous species Crucian carp. The results showed that Pterygoplichthys multiradiatus with Crucian corp in different proportions under any cir- cumstances were shown to reduce weight, Pterygoplichthys multiradiatus dropping more weight than Crucian carp, but both positive growth trend. Pterygoplichthys multiracliatus and Crucian carp presented competitive relationship, and Crucian carp showed stronger competitive capacity.
