Spatio-temporal characteristics of land cover changes of Liangjiang new destrict in China during 2010-2018

Abstract

Based on WorldView-2 remote sensing images and other survey materials, we analysis the spatio-temporal characteristics of land cover change in Liangjiang New District during 2010 to 2018. The results are summarized as follows: 1) Land cover pattern changed dramatically, with the built-up increase, while the crop land, forest and grass land decrease. 2) Change in land cover types showed marked fluctuations over the three stages (2010-2012, 2012-2015, 2015-2018). Districts with the most obvious change of CL and FGS concentrated in the East and north of the Liangjiang New District. 3) There were significant differences in the intensity of land use dynamic degree change among different regions. The relative change land use dynamic degree of Lijia Street is the biggest, followed by Yuelai Street, Fusheng Town and Longxing Town.
