Abstract: The large increase of urban-rural construction land is the main feature of modern land use.Based on the data of land use in 2005, 2010 and 2015, the spatio-temporal evolution of urban-rural construction land in the south bank of Hangzhou Bay is studied, which combined   with GIS spatial visualization using land use structure model, dynamic attitude model, landscape model. The results show that:(1)Urban and rural construction land is the largest increasing and the fastest growing in the area of all land use types in the south bank of Hangzhou Bay, but the growth rate has slowed down.; (2)The construction land of the town has the fastest growth rate, and the water conservancy facilities and the area of independent industrial and mining land are decreasing. Construction of the town of land and traffic land have the largest land dynamic, village and water conservancy public facilities are the lowest degree of dynamic; (3)Construction of the land composition:designated town land> village> city> traffic land> water conservancy and public facilities> independent industrial and mining land, the overall balance has declined,the dominance of designated town land is gradually emerging; (4)The spatial distribution of the land for construction is in the form of a polar nucleus and a belt, scattered and gradually expanding northward; (5)Before 2010, the construction land showed a fine grain dispersion development characteristics, which is to the coarse grain development after 2010, and landscape heterogeneity weakened.
