HEDGEROW NETWORKS IN THE LANDSCAPE SUPPORT MULTIPLE ECOSYSTEM SERVICES IN CEREAL CROPS

摘要

Over the past half-century, agricultural intensification has dramatically increased transforming agricultural landscapes into simplified monocultures with low cover of semi-natural habitats. This trend, often called 'landscape simplification', has ledto a loss of biodiversity and possibly to the deterioration of key ecosystem services to agriculture (e.g. Tscharntke et al., 2012; Tamburini et al., 2016).For this reason, several interventions have been suggested to enhance ecosystem services in farmland (Bommarco et al., 2013). Field-margin diversification through the conservation and restoration of hedgerows is becoming a prominent intervention for promoting biodiversity and ecosystem services in intensive agricultural landscapes. However, how increasing hedgerow network in the landscape can affect ecosystem services has rarely been considered.Here, we assessed the effect of increased field margin complexity at the local scale and hedgerow cover at the landscape scale on the provision of aphid pest control, weed control, and potential pollination in conventional agriculture fields.
