The formation and evolution of theo network of economic geography in the Zhu-jiang Delta is a process of time-elapse and space-expansion,demonstrating its distinctive laws.In the Yuan Dynasty and before,this network was at its embryonic stage,during which a pattern of geographical points and axes formed,radiating scatteredly,with Guangzhou as its single centre and with relatively small gravitates sphere.In the Ming and Ching Dynasties,based on economic development,a net-work of "T" pattern formed,with Guangzhou and Macao as two centres and the Guangzhou-Macao axis running vertically through north and south,and the Guangzhou-Foshan-Chencun-Shilong axis running horizontally through east and west,radia ting strongly both inward and outward.After the Opium War,HongKong replaced Macao in importance and the vertical axis of the network moved eastward.The coverage of the network enlarged continually,stepping into a stage of expansion,which sustained on after liberation.In the recent dacade,along with the economic soar in this delta,a network of trapeoid pattern formed with three centres (Guangzhou,Hong Kong,Macao) and two vertical two horizontal axes,which has become apattern of two-side development and two-way radiation.
