中文摘要：

旅游区在旅游系统演化中扮演着重要角色.研究以洛阳龙门石窟旅游区为案例区,采用GIS空间分析等研究方法,对该区土地利用格局演化进行分析,揭示演变规律,在此基础上剖析促使其演化的驱动力因素.结果表明,龙门石窟旅游区用地面积持续快速扩张,用地速度强度持续增加;林草地、农用地、风景点游赏用地、商服用地、居民社会用地为增减幅度和变化强度最大的用地类型;研究区空间变化表现出明显的分异规律;旅游区正在从观光游览型向旅游休闲度假型转变,旅游区时空拓展、生态治理及商服配套建设加速,但存在用地扩张过快、遗产＂文化生态＂受到挑战及趋＂人工化、商业化、城镇化＂倾向.

英文摘要：

Tourist attractions play an important role in the evolution of tourism system.The research takes the Longmen Grottoes tourist attractions of Luoyang as the case,applying GIS spatial analysis,a dynamic land use model,and other methods to study quantitative structures,time series,spatial changes and other factors from multi-dimensions.The changing law of the land use and spatial temporal characteristics are analyzed to reveal the inner mechanisms,on which basis to further analyze the driving force that makes the evolution.The results of the research indicate that continuous rapid expansion and increasing speed of the land area of Longmen Grottoes havs made land use patters change enormously in both speed and intensity of the land use.Among the referred patters,the scenic forest and grass land,agricultural land,commercial land,residential land and the land for scenic area and recreational facilities are the fastest ones either in increase or decrease amplitude or intensity of changing.Spatial changes of Longmen Grottoes show an obvious differentiation and visitors come to the site for leisure tour rather than sightseeing,thats to say,the tourist attractions have become used to playing its role from pure sightseeing to leisure tour,which contributes a lot to the acceleration of the spatial expansion and eco-environment management and commercial service amenities.However,problems such as the fast expansion of the land use,the challenges to the cultural ecological environment and the tendency to artificialize,commercialize and urbanize the site arise spontaneously（at the same time）.
