Abstract
This paper took Shangbao terraced field in Chongyi County as the research object. With the DEM data of Chongyi County and Google Earth images as data sources, this paper obtained Shangbao terraced landscape by vectorization and calculated the landscape metrics through Fragstats 4.2, then analyzed landscape granularity effect and the landscape changes in different elevations, finally we made a comparation between Shangbao terraced field and Hani terrace field in Yuanyang County. The results indicated that: 1) Shangbao terraced field has high Landscape fragmentation, the patch shape is more irregular and the landscape has high aggregation; 2) Terraced field landscape metrics change significantly with the scales change, the landscape metrics are strongly scale-dependent; 3) The terraced field gradient is obvious, terraced field mainly distribute in the range of altitude between 500 m and 800 m, terraced field landscape fragmentation is highest at altitude more than 1000 m, the patch shape is most irregular in the range of altitude between 800 m and 1000 m, aggregation is highest in the range of altitude between 300 m and 500 m; 4) The landscape fragmentation of Shangbao terraced field is higher than Hani terraced field, and the landscape aggregation is slightly higher than Hani terraced field, and the patch shape is relatively regular than Hani terraced field.
