矿产资源开发和利用在产生巨大经济和社会效益的同时，也对所在地区的生态环境造成重要影响。为探讨福建省罗源县石材矿开采区十年间的变化，基于2001年和2010年的中高分辨率遥感图像，采用了结合决策树算法、回溯方法的面向对象分类技术提取矿区地表覆盖及其变化信息。结果发现，十年间罗源县工矿面积从2．09km2增加到7．89km2，矿区复垦面积却只有0．62km2；矿区斑块数、斑块面积变化研究和实地考察结果表明罗源县矿山开采有规模化发展趋势。

Exploitation and utilization of mineral resources has brought immeasurable economic and social benefits,and has also resulted in serious impact on the local ecological environment.To monitor the decadal change of stone mining areas in Luoyuan County of Fujian province,land cover information was extracted based on the 2010 and 2001 high resolution remote sensing images,and the technique of object-oriented classification combined with decision trees and the strategy of back-date was employed to extract the land cover change information during the ten years.The results show that stone mining area increase from 2.09m2 to 7.89km2 ,nearly quadrupled during the ten years.However,reclaimed land in the mined area is very limited, only 0.62km2 .Changes of patch number,average patch area of the mined area and results of inspection indicate that the mining in Luoyuan County has undergone a process of scale development.
