    以三峡库区30 m分辨率的ASTER GDEM数据为基础，在GIS系统的支持下，采用邻域分析方法提取地势起伏度，运用均值变点分析法对其进行了最佳统计单元的计算.研究结果表明，三峡库区地势起伏度最佳分析窗口为44×44网格(1．74 km2).同时，完成了三峡库区地势起伏度分级图的绘制.

    The optimum statistical unit of the relief amplitude in the Three Gorges, extracted by neighborhood analysis, was achieved using mean change-point analysis, based on the AETER GDEM data of 30 m resolution with the GIS system support. The results show that the optimum statistical unit of the relief amplitude in Three Gorges area is the 44 × 44 mesh size ( 1. 74 km2 ) . A drawing of the relief amplitude grades of the Three Gorges area is also completed.
