资阳市中心城区土地利用与土地覆被时空动态变化分析

Research of Land Use/Cover Spatial dynamic change in Downtown of Ziyang City

根据1996年和2008年两个时期的LandsatTM卫星影像资料,运用地理信息系统空间叠加分析和数理统计的方法,全面分析资阳市中心城区12年间土地利用方式的变化,从土地利用分布面积和空间两个方面分析其变化特征,结果表明建设用地通过占用耕地扩展,非建设用地结构发生明显变化。研究成果为土地利用规划和可持续利用提供有效的决策支持。

According to the 1996 and 2008 two period Landsat images, This paper analyses Ziyang city12 years of land use change by using Geographic Information System spatial overlay analysis and mathematical statistics. The paper reveal the land use Variation characteristics of the area and spatial in the study area, The results show that construction land through expansion of culti- vated land occupied, the construction land use structure change greatly.
