本文根据实景三维中国建设和新型基础测绘体系建设的需要，结合贵州省多源异构地理信息数据特点，明确了地形级基础地理实体转换的内涵和内容，然后对其转换生产的流程及技术方法进行了梳理介绍，为贵州省乃至整个西南复杂地物区域的地理实体转换生产提供了相应的内容参考。

Based on the requirements of the “Realistic 3D China” initiative and the construction of a new fundamental surveying and mapping system, this paper clarifies the connotation and components of terrain-level geographic entity conversion by integrating the characteristics of Guizhou’s multi-source heterogeneous geographic information data. Furthermore, it systematically outlines the conversion production process and technical methods, providing a valuable reference for geographic entity conversion in Guizhou Province and other complex terrain regions across Southwest China.
