基于1995、2000、2005、2010、2015年Landsat TM/OLI遥感影像,运用监督分类法提取楚雄市土地利用类型,并对楚雄市城镇扩展空间分异特征、城镇空间形态特征进行分析,最后建立城镇化综合评价测度体系,对楚雄市城镇扩展驱动力进行分析。研究结果表明:(1) 楚雄市在过去20年间城镇不断向外扩展,速度逐渐增大,北部地区城镇扩展速度较快,南部地区城镇扩展速度缓慢;(2) 城镇形态逐渐趋于复杂化,城镇紧凑度减少,城镇内部土地利用率减少; (3) 其中经济指标是推动楚雄市城镇化进程的主要因素,地域景观指标次之,人口指标对于城镇化进程的影响最小。
Based on 1995, 2000, 2005, 2010, and 2015 Landsat TM/OLI remote sensing images, this paper used the supervised classification method to extract land use types in Chuxiong City, analyzes the characteristics of urban expansion spatial differentiation, characteristics of urban spatial form, and driving force of urban expansion in Chuxiong. The research results showed that: (1) In the past 20 years, the urban in Chuxiong has been expanding outwards, and the speed has gradually increased. The urban expansion in the northern region has been rapid, and the urban expansion in the southern region has been slow; (2) The urban morphology was gradually becoming more complicated, the urban compactness was reduced, and the urban land utilization was reduced; (3) Economic indicators were the main factors driving the urbanization process of Chuxiong city, fol-lowed by regional landscape indicators, and population indicators had the least impact on the ur-banization process.
