Article Synopsis
- Desertification poses a significant threat to ecological systems and economies, highlighting the need for effective assessment methods at various scales.
- The study focused on the Ordos Plateau in China, utilizing Landsat data to create a quantitative assessment method that accurately evaluated desertification from 1980 to 2000 with over 90% accuracy.
- Findings revealed a general decrease in desertification over this period, attributed to climate change and human conservation efforts, though some areas did experience increasing desertification due to human activities.
Based on the zoning regulation which integrated climate, vegetation and soil as a complex, a regional eco-security index system consisting of regional physical background, ecosystem stability, landscape structure, and external interference was established, and, with the support of geographical information system technology and fuzzy mathematics, a set of regional eco-security assessment methods was constructed. By means of these methods, the eco-security index of southwest Beijing in 2004 was calculated based on the recent 30 years background data of climate and soil. The results showed that in southwest Beijing, the eco-security degree was higher in its central area and western hilly-shallow hilly areas, but lower in its southern and southeastern plain areas.
