Abstract: Taking ENVI and ArcGIS as the main technical platform and the landscape security pattern of Xiamen was analyzed by the "patch-corridor-matrix" mode. Taking natural factors and social factors into consideration, and giving the different factors different resistance value and weight, the three kinds of urban sprawl plan was made: urban sprawl preferred plan of low security level, coordinate development plan of medium security level and the plan of ecological conservation priority plan of high security level. The minimum cumulative resistance model (MCR) was applicated to establish respectively the cumulative resistance surface of three plans, and comparative impact evaluation for these plans were showed as follows: (1)The area suitable for urban land of three different security levels were 694.87 km², 575.1 km², 454.96 km². The new land was provided new land for urban expansion area of approximately 433.12 km², 313.12 km², 193.21 km². (2)With the security level development, the ecological land gradually increased, but suitable land for urban construction is being less. (3) The urban growth pattern based on low security level and medium security level can be both provided for the requirements of urban expansion land of Xiamen in“Twelve-Five-Year”plan for 2020 forecasts, and taking ecological protection for consideration priority the pattern of the high level of safety required of construction land need to make concessions.
