摘要:
 以2000年和2009年2期TM遥感影像及2012年高分辨率ZY-3遥感影像为主要信息源,结合西安市土地利用图及实地调查分析数据,通过支持向量机的监督分类方法以及景观指数分析法,借助RS和GIS软件平台,分别得到2000-2012年间西安市主要城区景观格局演变状况。结果表明,2000-2012年间西安市城市景观格局破碎化和同质化并行,建筑用地面积增加72.68%,林地景观面积减少9.01%,水体景观面积减少24.05%,耕地面积减少53.96%。人为活动影响显著。
Abstract:
 TM images of remote sensing in 2000 and 2009, as well as ZY-3 images acquired in 2012 were adopted as important data sources, combined with the local land use map and field investigation data, and aided by RS and GIS software platform, the spatial temporal evolution of landscape pattern in Xi’an from 2009 to 2012 were obtained. Three images were classified by using support vector machine. The results revealed that the urban landscape pattern in Xi’an presented fragmentation and homogenization from 2000 to 2012. The building land increased by 72.68%, and the woodland decreased by 9.01%, furthermore the water landscape declined by 24.05%, and the cultivated land dropped by 53.96%. The disturbance of human activities was significant.
