珠三角地区是我国发育比较成熟的都市经济区。伴随着快速的城市化进程,人口和产业的集聚与扩散越来越明显,空间格局不断发生着变化与重组。通过高分辨率的TM遥感影像和Google Earth数字影像,运用Envy、Arcgis等空间分析软件进行空间解译和类型判读,客观地刻画珠三角都市经济区目前的空间格局特征与存在的主要问题。最后,针对珠三角都市经济区出现的各种问题,从重视空间安全、提高空间利用效率、促进空间优化组合等角度提出空间结构优化的对策与建议。
The Pearl River Delta is a developed metropolitan economic zone in our country. With the rapid process of urbanization, the concentration and diffusion of population and industry become more and more obvious. The spatial pattern is constantly changing and reorganizing. Through high-resolution TM remote sensing images and Google Earth digital images, spatial interpretation and type interpretation are conducted using spatial analysis software such as Envy and Arcgis to objectively characterize the current spatial pattern and existing problems in the Pearl River Delta Metropolitan Economic Zone. Finally, in view of the various problems in the Pearl River Delta Metropolitan Economic Zone, the countermeasures and suggestions for the optimization of the space structure are put forward from the perspectives of stressing on space security, improving the efficiency of space utilization, and promoting the optimization and combination of space.
