Abstract：Land consolidation is one of the driving forces to the landscape change, its ecological effects of land consolidation can be represented through the change of landscape patterns. Based on AutoCAD and MapGIS, the 3 factors with 9 indexes are selected to be calculated the changes in fore-and-aft the land consolidation with the spatial and attribute data of state invested project of land consolidation for basic farmland in Anlu City, Hubei Province. The results show, the index of patch density is reduced, the index of landscape diversity decreased, the degree of fragmentation fallen down, the dominance of paddy field increased, and the connectivity enhanced after land consolidation. The results also show, the degree of landscape heterogeneity is degenerated, the landscape patterns are tended to simplification and disequilibrium, the spatial distribution of every kinds of patch in landscape is also appeared to disequilibrium.
