摘      要：One of the most important issues related to landscape ecology and ecosystem services is finding the pattern of habitat patches that offers the highest pollination in agricultural *** this regard,two processes of habitat loss and fragmentation strongly affect the relationship between pollination and the pattern of habitat *** the present study,we aimed to examine the effects of habitat loss and fragmentation on pollination *** this purpose,first,we generated different simulated agricultural landscapes,including two habitats of forest and ***,according to the Lonsdorf model,we estimated the potential of the simulated landscapes in providing pollination in different ***,using statistical models,we estimated the effects of habitat loss and fragmentation on pollination at the landscape and farm *** results showed that the effects of habitat loss and fragmentation on pollination were completely different at the landscape and farm *** the landscape level,fragmentation negatively affected pollination,but at the farm level,the maximum pollination rate was observed in the landscapes with a high degree of *** the habitat loss effects,our results showed that pollination decreased linearly at the landscape level as habitat amount decreased,but at the farm level,it decreased *** present study considered the level of analysis(i.e.,landscape and farm levels)as a critical factor affecting pollination changes caused by *** showed that using the Lonsdorf model could lead to confusing results for the landscape ecologists and alert farmers who want to reduce the adverse effects of fragmentation on their products by creating new forest ***,agriculturalists and landscape ecologists should consider that the pollination rate at the landscape and farm levels is completely different according to the model and provide contradictory results about the process of habita
