资源环境信息（地理信息）具有时空特点，其种类复杂、获取渠道多样、具有多种比例尺和分辨率以及不同的表达方式，因此，资源环境信息是多维的。遥感（RS）、地理信息系统（GIS）、全球定位系统（GPS）和数据库（DB）等现代信息技术为资源环境科学的发展起了巨大的推动作用，是资源环境科学由以定性描述为主走向定性、定量、定位综合研究的技术基础。然而，面对多维的资源环境信息，要构建一个具有多维信息表达方式、人机和谐、交互性和参与感强、满足资源环境科学研究人员需要的多维信息处理平台，仅靠这些技术是不够的。作为现代信息技术发展的重要分支，虚拟现实（VR）技术适应了这一形势发展的需要，它已经在许多领域得到广泛的应用。在描述资源环境科学多维信息特点的基础上，重点探讨了如何利用虚拟现实技术及其它信息技术构建满足研究人员需要的资源环境科学研究多维信息平台、它的功能以及实施方式。

Resources and environment information has spatial and temporal features, it consists of various types and can be gained by many kinds of means, so it is multi-dimensional. Existed modern information technology, such as Remote Sensing(RS), Geographical Information System (GIS) and Database(DB) ,has promoted development of resources and environment sciences to great extent, but it is still difficult to construct friendly user interfaces for expression and processing of multi-dimensional information with these technologies. However, Virtual Reality(VR) technology meets this requirements just in time.
On the basis of describing the features of resources and environment information, the paper puts emphasis on discussing how to construct a new generation of information platform for resources and environment research with modern information technology, especially with VR technology. The functions of the information platform include: (1) search and query of scientific documents, (2) link between spatial data and attribute data, (3) reflection of dynamic changes for resources and environment, (4) conducting routine analysis with models, (5) visualization of 3D geographical environment with VR technology, and (6) data mining. In initial stage, implementation of the platform will mainly rely on VR software, instead of hardwares, such as data gloves, Head-Mounted 3D Display(HMD).
