基于QuickBird影像的矿区土地利用变化研究

Study on the Land Use Change in Mining Area Based on QuickBird Image

文中以2001年DLG(数字线划图)和2005年QuickBird影像为数据源,运用遥感(RS)和地理信息系统(GIS)技术来研究矿区土地利用变化。根据文中转移矩阵与两时期各种用地类型统计数据,采用土地利用结构指数与土地利用多样性指数两种指标体系对矿区的土地利用变化进行定量分析。经分析得到如下结论:(1)矿区建设侵占用农田的现象仍然比较突出;(2)两时期的土地利用多样性相对较低。据此本文为矿区的可持续发展提出了几点对策,为矿区土地的科学规划与合理利用提供了技术支持。

In the paper,the author studies the land use change in mining area using remote sensing and geographic information systems(GIS) in 2001 DLG(DLG) and 2005 QuickBird image as a data source.The author quantitatively analyzes the land use change in mining area using the land use structure and the land use diversity index according to the matrix and statistics data of two periods,transition matrix and various land types data during two periods.The results are the following conclusions:(1) Farmland occupation in mining area is still outstanding phenomenon;(2) Land use diversity index of two periods are still low.According to it,the author puts forward some suggestions for the sustainable development of mining areas.It provides the technical supports for the scientific plan and rational use of land in mining areas.
