Summary
Shenzhen
Area of Science:
- Geographic Information System (GIS) technology
- Remote Sensing
- Landscape Ecology
Context:
- Examining landscape spatial changes in Shenzhen over two decades (1978-1999).
- Utilizing Multispectral Scanner (MSS) and Thematic Mapper (TM) satellite imagery.
- Observing a dramatic transformation from agricultural to urbanized landscapes.
Purpose:
- To analyze the spatial and temporal dynamics of landscape changes in Shenzhen.
- To quantify the extent of urbanization and its impact on land cover.
- To identify the driving factors behind landscape transformation.
Summary:
- Cultivated land decreased from 31.06% to 2.67%, while built-up areas surged from 0.33% to 22.52%.
- Landscape diversity initially increased then decreased, while fragmentation and contagion indices showed complex trends.
- Human activities, driven by economic interests and industrial allocation, were the primary drivers of these landscape changes.
Impact:
- Provides crucial data for urban planning and sustainable development strategies in rapidly urbanizing regions.
- Highlights the significant impact of socio-economic development on landscape patterns and ecological conditions.
- Offers insights into the relationship between human activities and landscape evolution.
