Other Abstract 以都江堰市1980—2011年期间的建成区各年份的土地利用数据和社会经济数据为基础,借助城市周期扩张理论和分形理论,以GIS技术为支撑,揭示了都江堰城市形态演化的周期性、过程和机制。研究表明:1.都江堰城市形态演变遵循"外部扩张,内部填充"的周期扩张规律,演变周期为12~13 a,下一阶段将进入以内部填充为主的发展阶段;2.都江堰城市形态具有明显的分形特征,形态演变与所处的发展周期阶段有关;3.居住用地扩张是城市演变的内生因素,公共绿地空间分布不均衡,破碎化现象严重。4.都江堰城市形态主要受自然地理环境、经济发展、城市规划以及不可抗拒自然灾害的明显影响。 
; Based on the maps of urban land use and socio-economic statistical data,with the help of minimum costcycle expansion law of urban spatial morphology and fractal dimension theories,this paper chooses Dujiangyan city to carry out the cycle of urban morphology and the evolution of land-use structure. As well,the main driving factors were also revealed,including local geography environment,economic development,government management and the natural disaster. The results are revealed as follows: 1. The process of morphology evolution in Dujiangyan is the result of alternant pattern of external expansion and internal infilling of land use,the evolution cycle is about 12 -13 years,the city will be under the internal infilling period in the next station. 2. The character of self-similarity is very clear in Dujiangyan,when study the evolution of urban morphology and structure of urban land use using the theory of fractal dimension,the evolution of urban morphology is related with the development period. 3. The expansion of residential land is the endogenous factor of urban morphology,and the distribution of public green land is unbalanced. 4. the main driving factors of urban morphology were also revealed,including local geography environment, economic development,government management and the natural disaster.
