[目的/意义]知识组织系统（KOS）的构建依赖专家组的集体协商，以获取针对特定领域知识组织需求的概念体系，但其难以覆盖多领域资源组织需要。随着多样化知识的发展以及对复杂问题解决的需求，人们对多样化知识组织系统的构建提出了要求。基于多样化视角探讨知识组织系统构建的理论基础，可为多样化知识组织系统的构建及可持续性发展提供可参考的理论依据。[方法/过程]从主导KOS构建的两个关键要素：客体（资源环境）和主体（认识主体）出发分析KOS具有多样化的原因；进而探讨构建多样化知识组织系统的理论框架及基础，从而为多样化知识组织系统的构建及有机融合提供可参考的理论依据。[结果/结论]复杂的资源环境和个性化的认识主体思维是多样化KOS的主要促成要素。基于文献保证、关怀伦理、认识论、文化款待等多元理论明确了多样化知识组织系统构建及有机融合的理论思考，以便KOS适应多样化变化及发展需求的社会环境，促进其可持续发展。

[Purpose/significance] The construction of a knowledge organization system (KOS) relies on collective ne⁃gotiation among expert groups to obtain a conceptual system for specific domain knowledge organization needs, but it is difficult to cover the needs of multi domain resource organizations. With the development of diversified knowledge and the demand for solving complex problems, people have put forward requirements for the construction of diversified knowledge organization systems. Explores the theoretical basis of knowledge organization system construction from a di⁃versified perspective, can provide a reference theoretical basis for the construction and sustainable development of di⁃versified knowledge organization systems. [Method/process] This article mainly analyzes the reasons for the diversity of KOS from the two key elements that dominate the construction of KOS: the object (resource environment) and the sub⁃ject (cognitive subject); furthermore, the theoretical framework and fundamental for constructing a diversified knowl⁃edge organization system was explored, providing a reference theoretical basis for the construction and organic integra⁃tion of diversified knowledge organization systems. [Result/conclusion] Complex resource environments and personal⁃ized cognitive subject thinking are the main contributing factors to diversified KOS. Based on multiple theories such as literary warrant, ethics of care, epistemology, and cultural hospitality, the theoretical thinking on the construction and organic integration of diversified knowledge organization systems has been clarified, in order to enable KOS to adapt to the diverse changes and development needs of the social environment and promote its sustainable development.
