摘　　要：利用GIS技术和景观生态学方法,以成都市龙泉驿区为例,研究成都平原的景观格局变化特征及其驱动因素。研究过程中主要以1996年和2004年土地利用景观格局为基础,采用景观类型面积指数、景观破碎度、景观分离度、景观多样性指数、景观优势度、景观均匀度、景观形状指数分析区域土地利用景观格局变化特点。发现1996-2004八年间,研究区土地利用景观变化剧烈,各景观类型面积比例差异增大,土地利用结构混杂,景观破碎化程度变大,景观形状不规则化程度加剧。区域内部由于自然、经济、社会条件的不同,土地利用景观呈现出不同的特点。分析研究区土地利用景观格局的变化驱动过程,发现人口增长和第三产业发展是导致研究区土地利用景观格局发生变化的重要驱动力;工业化、城镇化、果业和乡村旅游业的发展是另一主要驱动力。This article takes Longquanyi district, Sichuan, as an example and then studies the changes of landscape structure and the driving factors by the technique of GIS and the method of landscape-ecology. We use the landscape acreage index, landscape fragmentation index, landscape apartness index, landscape diversity index, landscape dominance index, landscape evenness index and landscape shape index, to analyze the characteristics of the changes of landscape based on the landscape structure in 1996 and 2004. The landscape structure has intensively changed; the diversities of acreage ratio of various landscapes and the extent of landscape fragmentation have augmented a lot, the structures of land utilization get more complex, the extent of abnormity of landscape shape has enhanced. The villages and towns in Longquanyi have different landscape structures, due to the different physical, economic, and social conditions. And what＇s more, when analyze the driving powers of landscape structure, it is found that the increase of population and development of third industry are the leading driving factor; industrialization, the planting of fruit, and the tourism in rural areas are another driving power.
