Overview

Randomized trial evaluates ecological network resilience changes in a regional ecosystem, suggesting restoration priorities.

Key Points

  • This study aims to evaluate the changes in ecological network resilience over time in the Poyang Lake Eco-economic Zone.
  • Analyzed land-use data from 1990, 2000, 2010, and 2020 using multiple assessment methodologies.
  • Integrated Morphological Spatial Pattern Analysis, landscape connectivity evaluation, and robust simulations.
  • Conducted topological analysis to measure network metrics such as density, path length, and efficiency.
  • The area of ecological sources decreased from 39.97% in 1990 to 33.14% in 2020, indicating habitat fragmentation.
  • Network density increased from 0.10 to 0.15, while average path length decreased from 3.04 to 2.53, showing enhanced local connectivity.
  • The largest connected component reduced from 37 to 26, highlighting decreased regional connectivity and increased fragmentation risk.
