This study analyzed landscape changes in Shenzhen from 1979-2003 using satellite data. Rapid urbanization transformed natural vegetation into anthropogenic landscapes, with later periods showing consolidation and ecological impact mitigation.
Area of Science:
- Remote Sensing and GIS
- Environmental Science
- Urban Geography
Context:
- Analysis of landscape change in Shenzhen Special Economic Zone (1979-2003).
- Utilized satellite imagery from Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+), Multi Spectral Scanner (MSS), and SPOT.
- Focus on temporal-spatial dynamics and driving forces of landscape transformation.
Purpose:
- To investigate the characteristics, causes, and driving forces of landscape change in Shenzhen.
- To analyze distinct phases of landscape evolution between 1979 and 2003.
- To understand the impact of rapid urbanization on natural and anthropogenic landscapes.
Summary:
- Landscape change exhibited distinct patterns across three periods: rapid urbanization (1979-1990), formation of urban characteristics (1990-2000), and subtle consolidation with ecological considerations (2000-2003).
- Early urbanization led to significant degradation of natural vegetation, transforming it into anthropogenic landscapes.
- Later stages saw increased urbanization but with reduced intensity and measures to counteract adverse ecological impacts.
Impact:
- Provides insights into the complex processes of urban expansion and landscape evolution in rapidly developing regions.
- Highlights the changing intensity and nature of landscape transformation over three decades.
- Demonstrates the potential for mitigation strategies to address ecological consequences of urbanization.

Design Example: Sustainability in Concrete Building
There are multiple approaches to achieve sustainability in a commercial concrete building. For instance, construct a concrete parking area under the building, utilizing pervious concrete paver blocks in open areas to facilitate rainwater collection through an underground cistern.
