摘要

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 grid data in ArcView 3.3. Nine indexes have been selected for calculation based on Fragstats 3.3 and Excel 2007, including largest patch index, mean patch size, edge density, shape index, Simpson’s diversity index, Simpson’s 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.
