摘　　要：中国平原农区的空心村问题及一些地区开展的农村土地整治工程都对土地利用景观格局产生显著的影响.土地利用景观格局变化能够反映土地利用中存在的问题,为土地利用结构优化调整提供依据.以山东省禹城市为例选取1990年、2000年和2015年3期土地利用数据,在ArcGIS10.2和Fragstats4.2软件的支持下,利用景观格局指数分析土地利用景观格局变化及其驱动力.结果发现:1990-2015年间禹城市城镇用地和其他建设用地不断增大,耕地面积不断减小,农村居民点用地先增大后减小;各斑块类型在1990-2000年变化幅度较小,主要表现为城镇用地和农村居民点用地占用耕地,2000-2015年变化幅度大,突出表现在城镇用地和其他建设用地增大,耕地、林地、农村居民点用地和未利用地减小;景观破碎化程度加深,空间分布更加均匀;社会经济的发展、人口的增长和土地管理政策的调控是该区土地利用变化的主要驱动力.The Problem of Hollow Village in Plain Area of China and the land reclamation in the countr yside in some areas both have a significant effect on landscape pattern.The change of landscape pattern can reflect the problems in land use,and provide the basis for the optimization and adjustment of land use structure.Based on the data of land use in 1990,2000 and 2015,the landscape pattern index was used to analyze the change of landscape pattern and its driving force in Yucheng city under the support of ArcGIS 10.2 and Fragstats 4.2.The results showed that:The urban land and other construction land showed an increasing trend during 1990-2015,and the farmland decreased,the rural residential land increased first and then decreased;The change range of each patch type was smaller in 1990-2000 and larger in 2000-2015;In 1990-2000,it is mainly for urban land and rural residential land occupation of arable land,and in 2000-2015,it is mainly for urban land and other construction land increased,arable land,forest land,rural residential land and unused land decreased;The Landscape fragmentation deepened,the spatial distribution is more uniform;Socioeconomic development,population growth and land management policies are the main driving forces of land use change in Yucheng city.
