摘要:Water Resource is one of the most important nature resources, and it is the strategic resource for economic development. With the development of industry and agriculture, city population increasing, more and more water is needed, as well as the groundwater. It causes the groundwater over-extraction, and a series of serious environment problems such as region's groundwater cone of depression, land subsidence, seawater inbreak, water quality deteriorate. It is very necessary for us to study groundwater resource. Traditionally, 2D data model is used and 2D planes and slice are represented the result, not the true 3D, so it is difficult to analyse groundwater resource exactly. Therefore, Volume visualization technology is introduced into the field of groundwater resource.Volume visualization technology is that scatter sampling in finite space, each value of sampling point will be one or more properties, which represent its physical property. So it is very suitable to represent the true 3D geo-phenomena, such as the existent condition of groundwater, the groundwater cone of depression and the groundwater effluent seepage field. This paper researches how to represent the time-space distribution and dynamic change characteristic of hydrogeologic layer and its inner physical and chemical attributes, such as intrinsic permeability, porosity, water quality, groundwater temperature and so on, groundwater effluent seepage field moving regulation, represent the development procedure of groundwater cone of depression. Thus it provides the scientific foundation of decision support for the extraction of groundwater. Central contents including: 3D modelling of existent condition of groundwater, 3D modelling of groundwater effluent seepage field and spatial data probe
