[Land use change in the eastern part of Chongming Island in Shanghai in recent two decades].
Under the support of Geographic Information Systems (GIS) and by using the aerial photos of 1982 and 2000, this paper analyzed the land use change in the eastern part of Chongming Island in past two decades. The results showed that agricultural land, water body, aqua-farm and coastal wetland were the main landscape components, and the land area for non-agricultural use was increased. The overall land use diversified increasingly. Agricultural land, aqua-farm and green land increased by 4050.2, 2566.2 and 901.4 hm2, respectively, while coastal wetland decreased by 7491.2 hm2. Aqua-farm was the land-use type with the highest annual change rate (54.6%), followed by green land (13.24%), traffic (4.49%), coastal wetland (-4.47%) and agricultural land (2.57%). The primary transitions of land use types were from coastal wetland to agricultural land, aqua-farm, green land and water body, from agricultural land to aqua-farm, residential land and green land, and from water body to agricultural land, aqua-farm and coastal wetland. Rapid socioeconomic development and government decision-making were the driving forces of land use change in the eastern part of Chongming Island.
