摘      要：The modern landscape patterns of islands usually show obvious spatial heterogeneity and complex ecological effects due to the vulnerability of ecosystems with natural characteristics under increasing human *** this work,we studied the variation in landscape pattern of the Miaodao Archipelago in Bohai Sea,North China,from 1990 to 2019,and an evaluation index system was established to explore the impacts of natural conditions and human disturbances on the ecological effects in the pressure-state-response(PSR)*** analysis was conducted on the natural conditions,human disturbances,and ecological *** results show that forest was the main component of the landscape pattern in the *** of the areas offorest and construction land were increasing,and the areas of cropland and grassland were *** landscape types changed slightly,and the landscape fragmentation was *** natural condition exhibited positive effects while human disturbance showed negative effects on the local *** disturbances come mainly from shoreline use while the natural conditions were mainly from the elevation *** ecological effects were resulted mainly from the net primary productivity and water yield.
