Human-induced land use/cover change (LUCC) has significant effects on the climatic and ecological processes at both global and regional scales. It is an important driving force of global environmental change and has been one of hot topics of international concerns. Since the industrial revolution, the expansion of built-up areas (construction land) has been profoundly changing the status of LUCC. Construction land expansion has been the most dominant feature in land use changes. People's lifestyles and ideas have changed a lot accordingly. It is urgent to to seek solutions to some global issues especially those in fields such as resources, environment and ecology. Historical LUCC research plays a key role in these fields. Confined by the data availability, reconstructing historical construction land confronts with some difficulties. Current research rarely targets at construction land along the historical timeline. There is room for research efforts in extending contents of such reconstructed dataset, quantifying key factors, and improving spatial analytical precision. Therefore, it is sensible to establish a method to reconstruct a more effective, comprehensive, and finer-precision dataset for construction land along the historical timeline. Based on historical records and contemporary statistics on natural resources, this study aims to reconstruct the spatial distribution of construction land (urban land and rural settlement land) for several selected time intersections in the past 200 years in Jiangsu Province with a resolution of 200 m×200 m. The results show that: (1) areas of construction land are estimated to be 963.46 km2 in 1820, 1043.46 km2 in 1911, 1672.40 km2 in 1936, 1980.34 km2 in 1952 and 10687.20 km2 in 1985; and (2) the spatial distribution of construction land are featured by a tendency to be close to water bodies and main roads as well as an effect of settlements’ polarization and diffusion. The validity of our research results has been proved indirectly by the trend test and the coordination analysis.
