Abstract: The purpose of this study is to analyze rural settlement evolution characteristics and the identification of main factors in Guangdong Province, which can promote the theoretical research and action implementation of rural transformation and spatial reconstruction. Methods of the landscape index analysis and the geographical detector were employed to reveal the expansion mode and mechanism of rural settlement from 1980 to 2015. The results show that rural settlement land in Guangdong presents a spatial expansion pattern with the pearl river delta as the main and the east and west as the auxiliary. From 1980 to 2015, rural settlement was dominated by marginal expansion, while the filling type changed and enclave type changed alternately. The evolution of rural land under urbanization shows significant stage characteristics and there are obvious differences between the master factors of different expansion mode. The identification results of main factors show that socio-economic factors such as per capita GDP, per capita grain output and per capita agricultural output value are the main controlling factors of rural settlements evolution in different periods. In 1990-2000 Guangdong was in a period of rural industrialization and urbanization, forming a trend of complexity of rural landscape elements, differentiation of spatial structure and diversification of regional functions. The area of rural settlements increased significantly. In 2000-2015, during the period of centralization and integration of rural planning, the change range of rural settlement land was relatively small. On the whole, Guangdong Province has gradually entered a high and steady stage of rural development and restructuring under the multifaceted synergy of "production-life-ecology". In conclusion, multi-perspective analysis of the evolution characteristics and mechanism of rural settlements are the theoretical supports for the optimization and reorganization of rural space, as well as the premise and foundation for the implementation of the strategy of rural revitalization and new type of urbanization.
