Using a combination of 0.25 m resolution aerial remote sensing data and topographic maps, the land use data for the Shanghai Huangpu River Water Source Protection Area in 2000, 2005, 2010, and 2015 were evaluated by means of manual visual interpretation. With the growth of industrial land from 2000 to 2015, there has been a relative decline in the proportion of agricultural land and water areas and a relative increase in the proportion of urban land areas. In the past 15 years, the areas used for farming and cultivating livestock and poultry have decreased by 44.17% and 71.65%, respectively. The area of water reduction has decreased by 6.44%. The area of green land forests, in contrast, has increased by 645.94%. The area of urban land has increased by 53.53%. All types of urban land use have increased, with the area used for industrial storage increasing the most at 21.77%. From the perspective of land transfer, the area of cultivated land transferred outward was the largest in the past 15 years, accounting for 22,839.96 hectares, and the transfer-outward rate of livestock and poultry farming land was the highest at 91.23%. The area of green land forests transferred inward was the largest at 16190.32 hectares; the transfer of industrial storage land inward was the second largest at 7979.12 hectares. Based on an analysis of development in the region, population changes, policy impacts, and other factors, our results indicate that urbanization and industrialization drove the increases in urban land areas; moreover, environmental policies affected green land areas as well as livestock and poultry farming land areas, market regulations affected aquaculture land areas, and environmental policies and urbanization affected water source protection areas.

Key words: Huangpu River, water source protection area, land use, driving force
