%X A spatial correlated model for metapopulation has been constructed, which not only includes population information about spatial structutre, but also introduces the global density and local density of distructed habitat. Model reveals the spatial distribution pattern of destructed habitat profoundly effect the dynamics and persistence of metapopulation. The mixed distribution of two habitat types makes against metapopulation increase and persistence and mean\|field assumption may overestimate the persistence of metapopulation in mixed habitat, but clustering distribution will promote its increase and persistence and mean\|field assumption may underestimate the persistence of metapopulation in clustering habitat. Metapopulation persisitence is also affected by species migration. The longer migration distance, the more possibly species resists extinction from habitat destruction. All the resluts show that not only the number of destructed habitat is a main cause incuring metapopulation extinction but also the spatial distribution pattern of destruct landscape profoundly effect the dynamics and persistence of metapopulation. All these results show that it is important to costruct the connectivity among patches although habitat restoration and habitat quality improvement is necessary.
