摘要
利用四期TM数据和GIS技术,分析了近20年南京城市边缘区城镇用地格局动态变化:城镇用地格局变化拐点在1994年和2000年,空间上表现出增长“热极”与“热带”;城镇用地格局变化阶段性是经济社会驱动过程演化阶段的反映,其空间特征是区域社会经济物质载体演化的体现,开发区是城镇用地增长首要来源,新市区与大学城是其增长核心和新形式,交通路网对其产生空间导向;但城镇用地增长相对处于规模扩张阶段,引致自然景观破碎化、社区“空壳”现象、大学城“圈地运动”耕地浪费严重。
Based on four-period TM remote sensing data and GIS spatial analysis methods,the paper describes urban land-use pattern dynamics of Nanjing city during recent 20 years. Urban land-use growth turnings occur in the year 1994, 2000; growth spatial differences show growth hot poles and hot belts. Urban land-use growth temporal differences are the results of economical and social development process and dynamics evolution： regressive analysis finds that relativity coefficient between urban land-use growth ratio and urbanization, GDP, and Development Area is very high. Development Area is the primary source of urban land-use growth in 1992; Dong-shan New Urban District and University City become spatial growth core and new spatial form; Airport and highway networks give guidance for urban land-use spatial pattern.
