The research perspective of land system science can provide a reference for the study of urban-rural integrated development promoted by land use transitions. Based on the review of the development of land system science, this paper discusses the theoretical framework concerning land use transitions affecting urban-rural integrated development guided by land system science, the influential ways and paths of land use transitions on urban-rural integrated development, and the measures of promoting urban-rural integrated development via adjusting and controlling land use transitions. Land system science is committed to monitoring land use change, explaining the driving forces and feedback mechanism, understanding the human-environment interactions occurring on land, and translating scientific findings on land system into solutions for sustainable land use. The operating of land system takes sustainable land use and human well-being as the criterions, and manifests as multi-dimensional effects of land use. Operating well the land system via scientifically adjusting and controlling land use transitions can affect the process of urban-rural integrated development. Land use transitions promote the integrated development of urban and rural areas under the effects of strengthening the whole and reinforcing weak links through four channels, i.e., efficiency improvement, value embodiment, development elements circulation and structure optimization. In order to promote the integrated development of urban and rural areas from the perspective of land system science, the adjustment and control of land use transitions need to reshape the land use rights system, to promote the integrated consolidation of territorial space, and to improve the management and control system of land use transitions.
