随着信息技术的发展和教育需求的不断增长，虚拟现实技术在教育中的应用更为广泛，它在环境创设、

人机交互、虚拟仿真方面的独特优势越来越受到教育界的关注。通过分析国内外Web3d 虚拟环境的研究现状，讨论

了虚拟学习环境构建的理论依据，在此基础上给出了系统构架和开发流程。以“义乌人虚拟博物馆”为例对其进行了

实现，以期为虚拟学习环境的开发提供依据。-With the development of information and technology and demand for more and better education，Virtual Reality Technology is

being widely used in education.And for its distinctive advantages in the establishment of environment，human-computer interaction and

virtual simulation，VRT arouses more and more extensive attention of the educational circle.In this article，Through analyzes the situation

of research on web3d virtual environment，discusses the theoretical support for building a virtual learning environment，and on this basis

presents the system formulation and development processes.In addition to that，taking Yiwu Virtual Museum as an example，the author

shows how to realize the system.The aim is to provide some valuable references for developing a virtual Learning Environments.
