Study on the Urban Fringe Based on the Expansion–Shrinking Dynamic Pattern

The urban fringe, as a part of an spatial form, plays considerably major role in expansion and shrinking. After decades rapid development, Chinese cities have advanced from simple stage to expansion–shrinking-coexistence stage. In shrinking expansion, the fringe shows different characteristics requirements for specific aspects such planning, land use, landscape, ecological protection, architectural thereby forming expanding fringes. A comprehensive study fringes their patterns is theoretically significant planning management, civilisation construction.
