Abstract: With increasing human disturbances (e.g., spatial fragmentation), drastic changes have taken place in spatial structure, which further affects the structure and function of ecosystem. The consequences of spatial changes on ecological processes are significantly associated with change in predator-prey interactions. Thus, exploring the relationships between spatial structure andpredator-prey interactions was of significance in understanding the underlying mechanisms of ecological changes in fragmented landscapes. This paper summarized current studies about the effects of typical spatial structures on predator-prey interactions, including the spatial size, spatial shape, spatial orientation, spatial distribution and spatial connectivity. Researches indicated that the stability and continuation of predator-prey system generally decreases with decreasing spatial size and connectivity, and excessive increase in the fragmentation of space, as well as changes in spatial shape and orientation which result in excessive increase in the grazing rate of predators. Effect of complicated spatial structure (coupled from above-mentioned structures) on predator-prey interactions, especially multispecies predator-prey interactions, should be focused on in the future.
