摘　　要：基于Maxwell的地貌学理论及GPS(geometrical product specification)区域法表面结构要素的规范特点,深入研究应用于表面形貌分析中的变化树及Wolf修剪技术;进一步规范区域、线、点等要素的Wolf修剪标准及表征表面结构的量化参数;并以实例阐述其在工程实践中的可行性。该表面分析技术不仅能便捷地实现微观表面形貌特定几何形状的提取和表面结构参数的量化,为微观表面几何形貌的分析开辟一条可行之路;同时也为新一代GPS区域标准的贯彻实施提供重要的技术支撑。According to Maxwell＇ geomorphology theory and the standardization characteristic of surface texture feature based on GPS＇ （geometrical product specification） areal method, deeply research the change tree and Wolf pruning technology which were used in analyzing surface topography. Further standardized the Wolf pruning standard of area,line and point feature etc and the quantification parameters of charactering surface texture. And expound its feasibility in engineering practicability by taking an example. The surface analysis technology can implement extraction of special geometrical form of microcosmic surface topography and quantification of surface texture parameters which can provide a practical way for analyzing microcosmic surface Geometrical geomorphology, but also provide a key technical support for implemention of new GPS＇ areal standard.
