摘要
主要基于RS和GIS的支持,获取了呈贡区2009~2014的两期遥感图像,并采用GIS的空间叠加分析的功能做土地利用转移矩阵,以此分析呈贡区城市扩张的驱动力和阻力。经过分析得出：呈贡区城市扩张的驱动力有：主体功能定位、基础设施建设和房地产开发投资;其阻力有：耕地保护压力、土地容量限制和有效需求不足。
Mainly based on RS and GIS support, access to two periods of the remote sensing image of Cheng- gong District from 2009 to 2014, and using GIS spatial overlay analysis features to make land-use transfer ma- trix, finally, analysis of the driving force and resistance was done. After analysis drawn： the driving forces of urban sprawl in Chenggong area are： the main function of location, infrastructure and real estate development and investment; their resistances are： pressure farmland protection, land capacity constraints and lack of effi- cient and effective.
