近年来，随着虚拟地理环境结构和功能的逐渐清晰，虚拟地理环境的地学分析及地理实验辅助功能逐步得到了重视。基于对地理学实验特征及任务的分析，讨论了虚拟地理环境对改进传统地理学实验的贡献，借此倡导基于虚拟地理环境以“虚实结合”的方法开展综合、协作式地理实验。

英文摘要：

In recent years, the structure and functions of Virtual Geographic Environments （VGEs） have become clearer and how they could be used to support geographic analysis and geographic experiment has received serious attention. Based on the analysis of the characteristics of geographic experiments, this paper discusses the potential contributions of VGEs to traditional geographic experimentation, thus to encourage researchers to perform geographic experiments based on VGEs in a fused reality-virtuality and collaborative way.
