摘　　要：[研究目的]针对各学科领域研究日益交叉融合的现象,分析文献环境中交叉概念的多样性水平,引入生态学视角为综合性叙词表中交叉概念的编制规则增添理论依据。[研究方法]基于生态学中群落交错区存在的边缘效应原理,将学科交叉文献类比群落交错区、叙词表交叉概念类比交错区物种,假设叙词表交叉概念具有多样性较高的属性,引入数量生态学,提出概念种类和概念相对密度指标,建立叙词表交叉概念多样性模型,以生物和农业学科背景为例,统计对比单学科和学科交叉文献环境中的概念多样性指数。[研究结论]相同大小文献环境中,生物-农业交叉概念的概念数量最多,概念多样性指数也最大,符合叙词表交叉概念多样性较高的假设。[Research purpose]Aiming the phenomenon of interdisciplinary research between different disciplinary,this paper analyses the intersecting concept diversity of thesaurus in the literature environment,and put forwards new theoretical basis of intersecting concepts during compiling comprehensive thesaurus by ecological perspective.[Research method]Firstly,based on edge effect principle in ecology,this paper made an analogy between interdisciplinary literature and ecotone,and drew parallels between intersecting concepts of thesaurus and edgespecies of ecotone.Then,this paper assumed that the intersecting concept diversity of thesaurus has a high level performance,introduced the concept types and the concept relative density by referring to quantitative ecology,and established a model of concepts diversity of thesaurus.Finally,this paper choose the biology and agriculture as a background,and compared the concept diversity index of single discipline and interdisciplinary literature environment.[Research conclusion]In the same number of literatures,there are the largest number of biology-agricultural concepts,which also has the highest concept diversity index.It consistent with the hypothesis that the intersecting concept diversity of thesaurus is higher.
