摘要
本文以Landsat TM遥感影像、HJ-1卫星CCD影像解译数据为基础,利用3S技术,得到西安市2000、2005及2010年土地利用/土地覆被数据。从空间分布变化、结构变化、类型转换及景观破碎度等角度,定量分析2000-2010年西安市土地利用/土地覆被变化及建成区扩展状况。结果表明:10年间,西安市耕地面积显著减少,转化为城市建设用地及林地;2010年西安市建成区面积较2000年增长了54.11%,空间分布上由城市中心向周边县区迅速扩张,导致周边连续分布的植被及未利用地趋势景观破碎化加剧。
In this paper,land use and land cover change maps of Xi'an City were extracted by interpreting Landsat TM images and HJ- 1 satellite CCD images from 2000,2005,and 2010 based on 3S technology. We analyzed and summarized the spatial- temporal features of Xi'an City and its built- up area from 2000 to 2010 which involved the spatial distribution change,structural changes,land use / cover change and the break up of landscape. The results show that the cultivated land area has been significantly reduced which converted into urban construction land and forest land during the last ten years. Compared with the year of 2000,the built- up area has increased by 54. 11% in 2010. It has expanded rapidly from the city center to the surrounding counties,which lead to a aggravation landscape fragmentation of vegetation and unused area with peripheral continuous distribution once.
