Analysis of land cover changes of Nanjing by remotely sensed data

Abstract

In this paper, land use/cover change (LUCC) from 2000 to 2010 in the region of Nanjing is studied, based on Landsat TM remotely sensed images in 2000, 2005, and 2010. The results showed that: from 2000 to 2005 and from 2005 to 2010, the area of construction land increased by 404.15 km² and 635.36 km², respectively. The farm land decreased by 105.49km² and 210.7 km², respectively during the two periods. The forest land decreased by 307.87 km² and 71.79 km². Water area increased by 10.54 km² from 2000 to 2005, and then decreased by 355 km² from 2005 to 2010.
