摘　　要：为了揭示煤炭开采驱动力与土地利用景观格局变化的耦合关系,应用GIS和RS技术,采用景观软件FRAG-STATS,从景观水平和斑块水平两个层次上对乌东矿区及其周边区域景观指数的变化规律进行了研究。结果表明:煤炭资源开采对区域影响强度的不同是区域景观格局产生梯度变化的主要原因。研究成果有助于探索煤炭开采对土地利用空间格局的影响,也可为同类地区土地利用空间格局的研究,提供科学参考依据。In order to determine coupling relationship between coal mining driving force and landscape pattern of land use,GIS and RS technology combined with landscape pattern analysis software FRAGSTATS were applied to analyze the change of landscape spatial pattern in Wudong mining area and its surrounding regions at the landscape level and patch level.The results showed that： the various effects of coal resources exploitation on the regions were the main reason that caused the change of landscape spatial pattern in the study area.The results will be helpful to explore the effects of coal exploitation on the landscape spatial pattern and can also apply a basement for the similar areas.
