Urban construction land expansion is an important topic of land use and cover change (LUCC). As an important cause of global climate and environmental change, it has attracted extensive attention of worldwide researchers and experts. China is one of the countries with largest utilization of construction land, most drastic change and most prominent land use conflicts induced in the world. In order to make profound analysis on the characteristic and presence of dynamic change in urban construction land use during the urbanization process in China, Hangzhou City is selected as the study area to analysis space-time changing rules in urban construction land use in Hangzhou during periods of 2004, 2007, 2010, 2015 and 2020. Based on the literature review and analysis on urban expansion and driving factors of Hangzhou, we designed classification and measure method of urban bubble. The research indicates that there were no urban bubbles in 2007 and 2015, while the urban bubbles in 2010 and 2020 is and will be 18.24 km2 and 40.62 km2, respectively.
