Itisundoubtedthatbiodiversityandits’ecosystemserviceshavesignificantimportanceforagriculturallandscape.The semi-natural habitats are the indispensable covers in agro-landscape, which maintain higher biodiversity becausetheyproviderefuge,foods,breedingplace.Tomeetthedemandsofagrowinghumanpopulation,agriculturalsystemshavebeenenlargedbyalteringnon-phabitatsareatocroplandandproducedmorecropsperunitarea,thedisturbancetoecosystemintensified inducing decreasing of biodiversity. Keeping high biodiversity in agricultural landscape is significantforsustainabledevelopmentofagriculture.Inthispaper,compositionandcharacteristicsofagriculturallandscapeheterogeneitywere reviewed and its effects on biodiversity and ecological service discussed.
