Abstract: In order to minimize the effect of spatio-temporal mismatches on land use spatial pattern analysis,we use a spatio-temporal integrated multi-temporal classification method.To detect the mismatches effects on landscape pattern analysis,we make comparison on landscape metrics derived from maximum likelihood classification and spatio-temporal integrated classification.Four metrics,including NP,ED,MPS and MSI,are used to check the differences on value and temporal trajectory between these two methods.
