Abstract
Investigating the changes in ecological carrying capacity around Qinghai Lake is of great significance for balancing human activities and natural resource pressures. It promotes the harmonious coexistence of economic growth and ecological conservation, ultimately leading to sustainable development. Using the equivalence factor method and the ecological footprint equation, we measured the ecological carrying capacity. The results show that: The ecological surplus around Qinghai Lake was 3.08×10⁴ hm² in 2000,19.93×10⁴ hm² 2010, and 11.93×10⁴ hm² in 2020. The overall trends of both ecological carrying capacity and ecological footprint are relatively stable throughout the study period. Notably, the ecological footprint consistently being less than the ecological carrying capacity, showing an overall ecological surplus. By analyzing the ecological carrying capacity and ecological footprint around Qinghai Lake, this study provides valuable insights for regional ecological construction.
