The Analysis Of Landform Of Fuzhou Basin Based On GIS

Synposis Geomorphology, Which is on the verge of geology and geography, is among the same series with different geographical subjects. It plays an leading roll on the issue of geologic ecology and reflects the characteristics of regional landform comprensively.On the basis of results researched before ,this study selects Fuzhou Basin as its research zone .classifies the landform types of Fuzhou Basin based on China 1:1000000 landform mapping standard, the actual situtation and the categorizing principle of form-genesis.Support by GIS and Rs technique.this paper manages GIS-aided landform mapping and landform factor mappings. By adopting unique space analyzing technique of GIS .especially its space overlaying function.this paper deeply analyses the landform characteristics and projects the landform database of Fuzhou Basin .Finally, according to the boundary of different landform types and different rock nature .with the characteristics that rock nature combines with landform structure being the landform classifying principle .this study classifies Fuzhou Basin into five landform subregions.
