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.展开更多
