focused in rural areas.(Lin, 1997).

7Spatial Transformation Mechanism in Rapid Rural Urbanization Process
Sub Question:• Which spatial elements involved?• How the involved elements interact?• What is the historical spatial transformation mechanism?• What are the difference between the past and current mechanism?• How the mechanisms change?• What are the difference with other urbanized deltas?• What are the casual factors make them different?
Research Question
How the urban landscape developed in the rapid rural urbanization process of PRD?
Key Words: Rural Urbanization, Urban Landscape, Pearl River Delta, Design Research, Typological Research, Spatial Transformation Mechanism,

0 • Strategic river cross.• No settlements in islands.• Delta not affected by settlements.

• Strategic region position.
• Settled on islands.
• Settlement affect the delta.
11Spatial Transformation Mechanism in Rapid Rural Urbanization Process
2000 • Spread without
landscape. • large reclamation lands.• Settlement dominated the formation of the delta.
