Landscape Pattern Analysis of Hainan Natural Meadow Based on Fragstats and Thematic Mapper
摘要
Abstract
In order to study landscape pattern of Hainan natural meadow, the interpretation has been conducted on TM of natural meadow by using ArcGIS 9. 3 and the vector data of natural meadow types in the test site have been obtained, which have been transformed into raster data in Art-View 3.3. Nine indexes have been selected for calculation based on Fragstats 3.3 and Excel 2007, including largest patch index, average patch area, edge density, shape index,Shannon' 8 diversity index,Shannon' 8 evenness index, fragmentation index, dominance index and separation index. The results show that landscape patch shape of natural meadow is simple, fragmentation index and landscape diversity are high and landscape indexes are highly correlated.关键词
