| 【目的】将遥感技术与社会统计学方法相结合，定量分析西安市城市化进程中城市景观动态的变化，并对城市化的驱动因素进行探讨，为西安市城市化和可持续发展提供理论支持。【方法】利用遥感技术和地理信息系统，获取并分析了西安市城区1988年、1995年和2006年3期的卫星影像数据。【结果】1988-2006年，西安市建设用地增加205%，水域增加3%，耕地减少37%，林地下降36%；耕地、水域破碎化程度严重，林地、建筑用地集中度提高。【结论】通过城市景观动态变化可以看出，西安市城市化驱动因素主要来自于政府政策导向和社会经济发展的需求；此外，城市化过程中的土地管理也是影响城市景观变化的一个主要因素。 |

| Abstract: |
| 【Objective】The urbanization process of Xi’an was quantitatively analyzed by combining the remote sensing technology with the social statistical method,and the driving factors were also discussed.【Method】With the aid of GIS based approach,three remote sensing images of Xi’an city in 1998,1995 and 2006 were analyzed.【Result】The results show that between 1988 and 2006,the area of construction land increased by 205%,water body 3%,arable land decreased by 37% and forest 36%.The landscapes of arable land and water body were severely fragmented,while the concentration of forest and construction land was increased.【Conclusion】Concluded from the urban landscape dynamics,the policy and social economic development are two main reasons for the urbanization in Xi’an,and the administration of the land resources also has vital impact on the dynamic of urban landscape. |
