摘  要:
基于江西省弋阳县区域ASTER-DEM(30 m×30 m分辨率)数据,运用ArcGIS10.2的窗口分析法提取起伏度,依次计算3×3,5×5…69×69窗口下的地形起伏度,采用变点分析法确定弋阳县地形起伏度的最佳统计单元为23×23,最佳统计面积0.4761km2。以地形起伏度为主,海拔为辅进行叠加分析,得到弋阳县基本地貌形态图,从形态图上可以看出该县地貌形态可分为7种类型,地貌类型主要以平原、丘陵为主,占总面积的2/3。

摘  要:
Based on the data of ASTER- DEM( 30 × 30 resolution) of Yiang County in Jiangxi Province,authors calculated the relief amplitude under the windows of 3 × 3,5 × 5 … 69 × 69 through window analysis method of Arc GIS 10. 2,and analyzed the best statistical element of mean relief amplitude using mean change point analysis. The results showed that the best statistical element was 23× 23,the best statistical area was 0. 4761 km2. Furthermore,authors composited topographic relief and altitude to gain the basic geomorphologic forms map of Yiyang County. The geomorphological types on this map could be divided in 7classes. The geomorphological types were main plain and hilly,accounting for 2 /3of all area.
