虚拟现实技术在水文地质研究中的应用

虚拟现实技术是利用计算机生成的虚拟环境逼真地模拟人在自然环境中的视觉、听觉、运动等行为的人机界面的新技术。利用虚拟现实技术沉浸感、与计算机的交互功能和实时表现功能，建立相关的地质、水文地质模型和专业模型，进而实现对含水层结构、地下水流、地下水质和环境地质问题（例如地面沉降、海水入侵、土壤沙漠化、盐渍化、沼泽化及区域降落漏斗扩展趋势）的虚拟表达。具体实现步骤包括建立虚拟现实数据库、三维地质模型、地下水水流模型、专业模型和实时预测模型。

Application of Virtual Reality Technology in Hydrogeological Research

Virtual reality technology(VRT) is a new human-computer interface technology that(vividly) simulates the human actions such as visual sense,hearing sense and movement in natural environment.The application foreground of VRT to hydrogeology is presented.The corresponding(geological,) hydrogeological and professional models are set up by using the immersion sense,interaction with computer as well as realtime forecast function of VRT so that hydrogeological conditions,groundwater flow,groundwater quality,environmental geological problems such as land subsidence,sea water intrusion,soil desertification,soil salinization-alkalization,swampiness and the development tendency of cone of depression caused by groundwater exploitation,can be represented in the virtual environment.The main steps in realizing virtual reality includes establishing virtual reality database,constructing three-dimensional geological model,establishing groundwater flow model,establishing professional model and building realtime forecasting model.
