[Purpose/significance] In the context of information overload, the amount of literature gradually rises. This paper draws lessons from ecological thoughts to discuss the stability law of concepts in the literature environment, and provides a theoretical basis for the preparation of a thesaurus from the interdisciplinary perspective.[Method/process] Based on the ecological niche principle, the authors made the literature environment simulate the ecological environment, that is, species corresponding to concepts, and the environment corresponding to the literature. The authors counted the number of concepts in the literature, examined the meanings of the concepts, verified the applicability of the ecological niche principle under the knowledge system, and proposed the change rule of the concept stability under the ecological niche principle.[Result/conclusion] In the same field, one theme in the literature is corresponding to one concept. The number of concepts remains stable. The meaning of the concept tends to be unitary. Both the number and the meaning of the concepts in the knowledge system comply with the ecological niche principle.
Key words： ecological rules; stability of concepts; thesaurus
